How To Maintain Transaction Order For Perpetual Inventory

Feb 9, 2008

Hello

I would appreciate If any one could help me in this matter.

problem is : how to maintain perpetual inventory transaction table order in batch mode updation ?.

I have designed a table to hold all inventory transactions. The table order is perfectly maintained in online system of updation. But if I go with batch updation then the order of the transaction is collapsing. For example consider the following table design. (note I used auto number to maintain the order).

version used : SQL Server 2000 with service pack updates.


LINEID TRANS_TYPE TRANS_ID TRAN_DATE STOCKNO QUANTITY RATE

1 Receipts 2 01/01/2000 xxxxx1 2 2.0
2. Issue 1 01/01/2000 yyyyy1 1
3 Receipts 3 02/01/2000 xxxxx2 4 3.0
4 Issue 2 02/01/2000 yyyyy2 1

the above is well in online mode. But in batch mode if i update issue 2 before receipts 3 then i am getting order like below

1 Receipts 2 01/01/2000 xxxxx1 2 2.0
2. Issue 1 01/01/2000 yyyyy1 1
3 Issue 2 02/01/2000 yyyyy2 1
4 Receipts 3 02/01/2000 xxxxx2 4 3.0

ofcourse if the order collapse means costing can not be accurate. so please any one could help me to solve this problem. because many software packages are not posting in sequence if we choose in batch mode.

Transaction-style Inventory?

Jul 20, 2005

Hello, I'm looking for a little input on this situation.I'm working on an inventory system and was thinking that I'd like tobuild it similiar to the way a bank keeps track of your funds.If you look at at bank statement, for each line item, you'll normallysee at least date/time, description, amount (plus or minus value), andbalance.In my inventory system, the amount and balance would be a count of theitems used or transferred instead of money.Does this sound reasonable? Or is there a better design? I am planningto connect the inventory system to a few different ordering interfaces,and I think it would work well if I can dump transactions into theinventory instead of incrementing and decrementing counts.The only problem I see with this, is if I want to implement the balancepart of it with each record....I can't think of a way to do that currently.I can certainly use a trigger in the database to retrieve the mostrecent transaction and update the balance field for one record insertedat a time, but if a list of transactions is dumped into the inventorysystem at once, I'd have to compensate for that in the trigger.Ideas?*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Apr 26, 2007

Say I have a result set with two fields numbers and letters.

1 A3 A1 B2 B


 The result set is ordered by the letters column. How can I select the distinct numbers from the result set but maintain the current order? When I tryselect distinct Number from MyResultSet

it will reorder the new result set by the Number field and return

123

 However, I'd like maintain the Letter order and return

Execution Order In A Transaction Batch

Feb 29, 2008

Is the order of execution guaranteed to go from top to bottom in a transaction that has multiple statements like below?


BEGIN TRAN T1;
UPDATE table1 ...;
UPDATE table2 ...;
SELECT * from table1;
UPDATE table3 ...;
COMMIT TRAN T1;


How about here?

BEGIN TRAN T1;
UPDATE table1 ...;
BEGIN TRAN M2 ;
UPDATE table2 ...;
SELECT * from table1;
COMMIT TRAN M2;
UPDATE table3 ...;
COMMIT TRAN T1;

how can i guarantee that statements will be executed from top to bottom in a transaction batch like above? I am not interested in the errors in statements. I just want whole thing to either execute fully from top to bottom or none executes

An Inventory Help...

Mar 12, 2007

Hi! I'm kinda stuck in getting a particularly tricky qurey...


SQL Code:






Original
- SQL Code




SELECT DISTINCTROW Categories.CategoryName, Products.ProductName, Sum(CCur([Order Details].[UnitPrice]*[Quantity]*(1-[Discount])/100)*100) AS ProductSales
FROM (Categories INNER JOIN Products ON Categories.CategoryID = Products.CategoryID) INNER JOIN (Orders INNER JOIN [Order Details] ON Orders.OrderID = [Order Details].OrderID) ON Products.ProductID = [Order Details].ProductID
WHERE (((Orders.ShippedDate) Between #1/1/1995# And #12/31/1995#))
GROUP BY Categories.CategoryName, Products.ProductName;






SELECT DISTINCTROW Categories.CategoryName, Products.ProductName, SUM(CCur([ORDER Details].[UnitPrice]*[Quantity]*(1-[Discount])/100)*100) AS ProductSalesFROM (Categories INNER JOIN Products ON Categories.CategoryID = Products.CategoryID) INNER JOIN (Orders INNER JOIN [ORDER Details] ON Orders.OrderID = [ORDER Details].OrderID) ON Products.ProductID = [ORDER Details].ProductIDWHERE (((Orders.ShippedDate) BETWEEN #1/1/1995# And #12/31/1995#))GROUP BY Categories.CategoryName, Products.ProductName;



The above SQL statement is from the famous Northwind DB and it is called the "Product Sales for 1995" query...

I have Transactions instead of Orders and TransactionDetails instead of [Order Details]

Now, I want something similar... I want to render Dead Stock and Fast Stock... I'm using ComponentOne's Reporting solution and it pretty much like Access.

Anyways, I want to supply a date for TransactionDetail.TransactionDetailDetail as starting date (ending date is always Today()) and within this range, i want to get a list of products that are sorted ascending on Products.ProductUnitSold. This should return a list of products (grouped by category name) showing SubCategoryName, ProductName, ProductUnitPrice, TotalSold...

If total sold is ascending = Dead Stock
If total sold is descending = Fast Stock

Inventory Table Design

Apr 17, 2008

I am designing a BI solution for a large manufacturer. They process big ticket items. They track their inventory by each piece. I need to know where each item is located, where it came from, when it arrived, has it been processed, ect. Along with that I have to be able to run reports by day/week/month/year that shows current inventory levels at any point in time.

What I arrived at for table design is each item will get a row which will include a column for date and another for Add_Remove. When the item is added to inventory it gets a date and a +1 for Add_Remove. When it is removed it gets a new row with a date and a -1 in the Add_Remove column. I should be able to add the Add_Remove column for the selected rows (by location, type, etc) from the beginning of time to any point in time and get a current total. If I'm reporting by month for the year I should be able to add from time(0) to lastitem in January to get January levels, then the same for each successive month.

The problem I can't figure out the MDX code to do that. My basic data set is as follows:

SELECT NON EMPTY { [Measures].[Total], [Measures].[Add Remove], [Measures].[Inventory Weight] } ON COLUMNS, NON EMPTY { ([Ship From].[Ship From Region].[Ship From Region].ALLMEMBERS * [Ship From].[Ship From].[Ship From].ALLMEMBERS * [Date Received].[Date].[Date].ALLMEMBERS * [Date Received].[Year].[Year].ALLMEMBERS * [Date Received].[Month].[Month].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM
( SELECT ( STRTOSET(@Region, CONSTRAINED) ) ON COLUMNS FROM
( SELECT ( STRTOMEMBER(@FromDateReceivedMonth, CONSTRAINED) : STRTOMEMBER(@ToDateReceivedMonth, CONSTRAINED) ) ON COLUMNS FROM
( SELECT ( STRTOSET(@InventoryType, CONSTRAINED) ) ON COLUMNS FROM
( SELECT ( STRTOSET(@Division, CONSTRAINED) ) ON COLUMNS FROM [Heidtman DW]))))
WHERE
( IIF( STRTOSET(@Division, CONSTRAINED).Count = 1, STRTOSET(@Division, CONSTRAINED), [Organization].[Division].currentmember ),
IIF( STRTOSET(@InventoryType, CONSTRAINED).Count = 1, STRTOSET(@InventoryType, CONSTRAINED), [Inventory Type].[Inv Type].currentmember ) )
CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS

Any ideas? I've tried adding ordered sets to the query with no success. I've tried calculate measures in the cube with less success. My time dimension includes every day from 1/1/1980 to 12/31/2050.

The one calculated memeber i tried - AGGREGATE ([Date Shipped].[Date].[Date].Item(0):Tail(existing [Date Shipped].[Date].[Date]).Item(0)) took 20 minutes to run in VS Browser and produced an error for every date in the time dimension......

Updating Inventory After Inner Join

Apr 30, 2014

I have this script which pulls in all products from a product inventory with a sku range starting in 9 and ending in BK

select Product.ProductID,Product.Name,Product.SKU,ProductVariant.Inventory
From Product
Inner join ProductVariant
on Product.ProductID=ProductVariant.ProductID
where Product.SKU like '9%BK'

If I wanted to add something to this script where the inventory for all those products in the results above was changed from 0 to 20 how would I add this? Just changing those who had a a SKU starting with 9 and ending in BK

Inventory Stock, Triggers Vs Views/SP

Jan 22, 2007

Hello..

I am designing a Database Application that covers Inventory System. And I am now in a dilemma of chosing which design to track Inventory stock better, in performance, reliability, and error free?




1st Design

PRODUCT TABLE
ItemID
ItemName
Price
QtyOnHand
..and other unique info of the product..

SALES TABLE
SalesID
Date
...etc...

SALESDETAIL TABLE
SalesID
ItemID
QtySold
Price

PURCHASE TABLE
PurchaseID
Date
...etc...

PURCHASEDETAIL TABLE
PurchaseID
ItemID
QtyPurchase
Price
...etc...

and similar design with SALESRETURN+DETAIL, PURCHASERETURN+DETAIL, ADJUSTMENT+DETAIL

Tracking Inventory stock is done by using (update, insert and delete) triggers in each of the DETAILS to update the QtyOnHand in the PRODUCT TABLE




2nd Design

PRODUCT TABLE
ItemID
ItemName
Price
...etc...

INVENTORY TABLE
ItemID
QtyBegin
...etc...

SALES TABLE
SalesID
Date
...etc...

SALESDETAIL TABLE
SalesID
ItemID
QtySold
Price
...etc...

and similar design with PURCHASE+DETAIL, SALESRETURN+DETAIL, PURCHASERETURN+DETAIL, ADJUSTMENT+DETAIL

The later design does not hold QtyOnHand, but only save QtyBegin instead. To get the QtyOnHand, it uses views/stored procedure with Union Query, so it looks like this:

QtyOnHand = QtyBegin + Sum(QtySold) + Sum(QtyPurchase) + Sum(QtySalesReturn) + ........

And at the end of a accounting period, the calculation of the QtyOnHand will be the QtyBegin of the next accounting period.

According to you guys, which way is better in PERFORMANCE, RELIABILITY, ERROR FREE, and why? What are the pros and cons of these two?

Thanks a lot.

Select Query To Calculate Old Of Inventory

Dec 24, 2014

I have to caculate the fifo inventory aging from purchase date, for example I have one item with 100 units in stock, and purchase this month 20 units, and 200 units three month ago, this item has 20 units this month and 80 units from 3 month ago.

Data is as follows:
<<<<< ORIGINAL DATA >>>>>>>>>>>>>>>>

Code:
Code StockPO Date PO_Qty
ao0-123100OC001010-08-2014 8
ao0-123100OC001110-08-2014 4

ao0-123100OC003112-11-2014 1
ao0-123100OC003212-11-2014 20

And the reuslt must be something like this:
<<<<< ORIGINAL DATA >>>>>>>>>>>>>>>> <<<<< CALCULATED DATA >>>>>>

Code:
Code Stock PO Date PO_QtyDays_Old Qty_From_PO Residue

ao0-123100OC003212-11-2014 20 41 5 0

I need to built a select to make this calculation, not using cursors, and build a view, only a basic select.

Rqst For Inventory Database Best Practices

Jan 30, 2006

I am developing an inventory database in SQL Server. I realize there aremany commercial (as well as some non-commercial) inventory offerings, but myclient has specific requirements that would necessitate significantcustomization of any off-the-shelf application. In the end, we decided itwould be more feasible to build one to our specifications.What I am looking for are a list of best practices/recommendations for thearchitecture and modeling of an inventory database. This inventoryapplication will be for managing a wholesale products operation. It mustmanage purchase orders to the manufacturer of the products, sales invoicesfor the retail customers of the products, as well as manage product stocklevels in the warehouse. We will need a number of reports, including:1. What products are in stock.2. What products are on order from the manufacturer.3. What products are needed to fulfill outstanding sales.4. Warehouse operations (e.g., receipt of delivery, inspection, add toinventory, pull from inventory, packing lists, invoices, return toinventory, etc.)5. Sales analysis (e.g., product velocity, sales by associate, etc.)My main question is regarding the managing of products in stock. As I see itthere are three ways of accomplishing this:1. Track only transactions (products received, products shipped, etc.) andcalculate the stock based on the sum of all transactions. But as transactionvolume accumulates over time, this would get very slow and cumbersome.2. Have a table of "units in stock" and add and subtract to it astransactions occur. This has the advantage of always providing an instantsnapshot of inventory levels. But it makes it more difficult to managechanges or corrections to a transaction once it has been entered.3. A combination of the above two concepts. Choose a point in time (forexample, when the warehouse inventory is audited) and capture that in a(semi) "static" table. After that, transactions are summed as needed againstthose static numbers. The next time the warehouse is audited, the "static"table is updated and all prior transactions are archived. New transactionsare once again summed against the most recent audit numbers. Of course, thiswould mean halting operations at the time of the audit (probably not anissue for my client's business).Recommendations? Suggestions? Comments?(Btw, I've tried to find this info in books and online, but so far have notfound anything that makes specific inventory system design recommendations.If you know of a good reference, please let me know.)Thanks in advance!Michael

Transact SQL :: Finding Ending Inventory Of The Day

Apr 30, 2015

I would like to know how I could code so that I can get the ending inventory of each day.  The following is my data

CREATE TABLE #TEMP
(
DATERCVD DATETIME
,ACCTID INT
,DATESENT DATETIME
)
INSERT INTO #TEMP VALUES ('01/01/2015', 1 , '01/05/2015')

[Code] ....

So my query results should be something like this:

InventoryDate Received Sent Ending
1/1/2015 4 1 3
1/2/2015 5 0 8
1/3/2015 3 2 9
1/4/2015 0 4 5
1/5/2015 0 5 0

TOTAL 12 12

SQL Server 2012 :: Calculating Inventory Turns

Aug 7, 2014

So I have been struggling with a way to perform inventory turn calculations in SQL. I'll start off with the formula. Basically the formula is Cost of Goods Sold over last 12 months / Average Inventory Value over the last 12 months. Short hand as COGS/AvgInventoryValue = Turns

In order to obtain the COGS value I take the Avg(UnitCost) * Sum(InvoicedQty) in the last 12 Months for Sales documents. This is represented as DOCUMENTTYPE = 2
Then divide AvgInventoryValue
To obtain the AvgInventoryValue I need to know the Quantity purchased in the 12 month period * Avg(UnitCost) + QuantityOnHand at the start of the period * Avg(UnitCost)
The purchased documents are represented with DOCUMENTTYPE = 6

The purchases will be positive since we are putting value in. The sales are negative since value is going out. I'll start with a simple example where the product is at zero Quantity On Hand at the beginning of the period.

--CREAT THE TEMP TABLE
create table #VALUEENTRY
(
ITEMNO VARCHAR (50) NOT NULL
, POSTINGDATEDATETIME NOT NULL
, DOCUMENTTYPEINT NOT NULL

[code]....

Is there another approach I should take to obtain the inventory turns?Also how do I account for periods earlier than 12 months where inventory is left over?In the sample data this item happened to be at zero inventory on hand at the start of the period. Also I believe it is my subquery's which are throwing the numbers off but I'm not sure how to isolate the subquery to just perform the result for a specific item. It is aggregating the entire table. How can I make the subquery more specific?

Transact SQL :: Inventory Difference Between Rows Between Stores

how to measure a change in inventory over various stores.  My sql2008R2 express db gets a new row of data everyday from each store(about 40 stores) for a single product stock count "OnHand" and if there is any new stock on order.  When the new stock arrives it is added to the "OnHand" count.   I want to measure the delta change per day,per store.  I'm stuck on how to separate the stores and how to query the delta of stock.My data base looks like this

Transact SQL :: Load 2 Tables With Data From 1 Inventory?

Oct 3, 2015

To setup some data in some new tables in t-sql 2012, I need to create a relationship between 2 tables were data is obtained from an inventory file. The inventory file will be loaded to sql server 2012 from an excel spreadsheet.

1. Columns that will be loaded to the first table are:

1. Inventory category number,
2. Inventory date,
3. Inventory Category total amount, and
4. Inventory category quantity on hand.

This table will have a column called Item number. This will need to be the value of item number that is in the second table.

2. Columns that will be loaded to the second table are:

1. Item Number,
2. item date,
3. Item price, Item quantity on hand.

Thus can you show me the sql that will load the table into both tables? This sql would also need to show how to obtain the values of item number from the second table and place that value into the first table.

Transact SQL :: Find Parts Matching In Inventory

Sep 15, 2015

We have an application where we want to check to see if the vehicle part on a job matches to our internal parts inventory (PartsInventory table) before we order it.  The problem is that sometimes the part number matches exactly and sometimes the part number has '-' or space but if those are removed, will match to our internal part number.  Below is what I have so far but it only matches exact part numbers.  One example would be if our part number was 1013738-00-C but the job (in RepairOrderLines) had a part number of 101373800C we should consider it a match.  Both PartNumbers are varchar(30). 

SELECT dbo.PartsInventory.PartNumber, dbo.PartsInventory.PartDescription, dbo.PartsInventory.VehicleMake
FROM dbo.PartsInventory INNER JOIN
dbo.RepairOrderLines ON dbo.PartsInventory.PartNumber = dbo.RepairOrderLines.PartNumber INNER JOIN
dbo.RepairOrder ON dbo.RepairOrderLines.RecordID = dbo.RepairOrder.RecordID INNER JOIN
dbo.Vehicles ON dbo.RepairOrder.VehicleID = dbo.Vehicles.VehicleID AND dbo.PartsInventory.VehicleMake = dbo.Vehicles.VehicleMake
WHERE (dbo.RepairOrderLines.RecordID = 46001)

Tricky Query, Get Inventory Count By Date Range

Mar 8, 2008

Hi,

My tables:

Product
- productID
- name
- price

Inventory
- productID
- stockCount
- timestamp

So each day the Inventory table has a new row for each productID with its stock count.

How can I create a report for the total products sold from one day to another? Or from what a dateStart from a dateEnd (i.e. a range)

Example:

ProductID StockCount TimeStamp
1 10 2008/03/07
1 7 2008/03/08

So you can see that 3 products were sold in the last day.

Create Inventory Report For Service Trucks By Adding All Transactions?

Aug 26, 2013

I'm trying to create an inventory report for service trucks by adding all the transactions that were used to restock the truck and subtract the transactions where the parts were used on an invoice and removed from the truck. All the transactions are in the same table. The fields that would be relevant are PartID, QTY, WhsTo and WhsFrom. If I wanted to calculated stock levels for truck 16 I would select all transactions that have a value of 16 in either WhsTo or WhsFrom. If WhsTo contained 16 then I would want to add QTY. If WhsFrom value was 16 then I would want to subtract QTY. I would want it grouped by distinct PartID. I don't know how to structure the Select statement to decide whether to add or subtract.

HELP! Synchronize Db And Maintain Foriegn Key Relations?

Jan 30, 2007

I have to synchronize 2 databases hourly but am having difficulty maintaining foreign key relations. These tables use auto-increment columns as primary keys, with child records in other tables related with foreign keys. I can't change the way the local software uses primary or foreign keys as it is hardcoded in the local app. (microsoft retail management system)..(however the web-remote app is easily customized). I am using CDB synchronizer to sync the two databases because the remote one is mysql.

Example tables layout:
Items table has auto-increment primary key 'id'
TransactionEntry table has its own auto-increment primary key 'id' and a foreign key 'item_id'

Example of how remote and local database foreign key relations are incorrect after sync using CDB synchronizer:
8:00am -first installation of database-'item' tables auto-increment 'id' columns match with id last record value of '6'

locally the following products are added:

11001 short sleeve t---gets added with primary key in 'item' table 'id' of '7'

11002 long sleeve t----gets added with primary key in 'item' table 'id' '8'

remotely the following products are added:

21001 hipster jeans- --gets added with primary key in 'item' table 'id' of '7'

31001 overalls---gets added with primary key in 'item' table 'id' '8'

remotely someone orders 21001..so TransactionEntry table records sale of "item_id" of '7', but after synch with our local server,

product with "item_id" of '7' is "short sleeve t".

9:00 -synch takes place...item_id foreign key isn't accurate because of independent auto-increment values..

whenever a product is ordered, the TransactionEntry table will record the product's ID column thats available in it's own local copy... after synch, the 'item_id' field will not match the 'Item' table id field and the data about the transaction's product is lost.

I have read of solutions involving staging/temporary tables to cascade update foreign keys before synching into main database, but hopefully there is a more elegant solution for this. If this is only way, will it be reliable? foreign key mix-match seems like could cause havoc.

Error 8525: Distributed Transaction Completed. Either Enlist This Session In A New Transaction Or The NULL Transaction.

May 31, 2008

Hi All

I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.

If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.

I've tried both with and without the Set XACT . . ., and also tried with Set Implicit_Transactions off.

set XACT_ABORT ON
Begin distributed Tran
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1 and DONE = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
COMMIT TRAN


It's got me stumped, so any ideas gratefully received.Thx

Maintain A Consistent DB Connection Through Application Lifecycle

Nov 10, 2006

Hey everyone, I'm new to .NET and I've recently inheirited a rather large and busy asp.net website.  I was asked to add a testimonials section on each page that will randomly pull a testimonial out of the db.  This is fine, however, I'm getting random errors about the DB connection either being closed or connecting.  Here is the code for the testimonials class: 1 public SqlDataReader GetTestimonials(ref SqlDataReader reader, int iCatID, string sLanguageType)2 {3 SqlCommand cmd = new SqlCommand("sp_DVX_Testimonials_Fetch", Connection);4 cmd.CommandType = CommandType.StoredProcedure;5
6 cmd.Parameters.Add(new SqlParameter("@Cat_ID", iCatID));7 cmd.Parameters.Add(new SqlParameter("@LanguageType", sLanguageType));8
9 reader = cmd.ExecuteReader();10
11 return reader;12 } I know this isn't the best way to do this (especially for each page[this site averages about 1000 hits a day]), so I was wondering was--is there a way to maintain a single DB connection that's set up in the Application_Start that will maintain the connection so I don't have to worry about this error.  If not, does anyone and any ideas as to what would help? Thanks in advance!
