I'm still fairly new to cubes, so bear with me. I'm trying to figure out if I should include aggregate data (e.g. total employees per facility) in a dimension table or if I should use the finished cube to get the counts (MDX?). Thanks for any help that you can provide.

I have three tables:
1) Contract - columns ContractNo and ContractName
2) SalesTransactions - multiple rows for each contract - relevant columns: ContractNo, InvoiceDate, Value
3) CostOfSaleTransactions - multiple rows for each contract - relevant columns: ContractNo, TransactionDate, Cost
How do I write a SELECT statement to produce rows containing:
ContractNo
ContractName
Sum of Value for ContractNo between @FromDate and @ToDate
Sum of Cost for ContractNo between @FromDate and @ToDate
Not all Contracts have either Sales or CostOfSales Transactions in the relevant date range and so one or both totals can be zero.
I've written something like:
SELECT CT.ContractNo, CT.ContractName, sum(CT.Value) as TotalValue, Sum(CS.Cost) as TotalCost
FROM Contract CT
INNER JOIN SalesTransactions ST ON CT.ContractNo=ST.ContractNo
INNER JOIN CostOfSaleTransactions CS ON CT.ContractNo=CS.ContractNo
WHERE (ST.InvoiceDate BETWEEN @FromDate AND @ToDate) AND (CS.TransactionDate BETWEEN @FromDate AND @ToDate)
GROUP BY CT.ContractNo, CT.ContractName
The TotalValue and TotalCost figures I get are much higher than expected. I presume this is something to do with the JOINs or WHERE clause. Please can you advise how I get the correct values?
I have a parent child dimension. a time dimension i have year.
Assume,

if I pass 2014 and 2015 in sub select 171 data is not coming in result. i i pass only 2014 in sub select i get value of only 2014. if I pass 2015 in sub select i didn't get any value.                                                                        Â
I have an Integration Services package that loads new data into tables that are dimension tables wi my cube. The same situation exists for my fact table. If I perform an "Analysis Services Processing Task" for the dimensions ,cube and measures, will that move the new data into my cube or do I need to perform the "Dimension Processing Destination" data flow task prior to this? Is the initial processing task good enough?
thx,

How do I correctly populate a fact table with the surrogate key from the dimension table?

View 4 Replies View RelatedHi, need help in this statement here. I have three tables here, i.e. Sales, SalesItem, & SalesPmt. I want to display a grid that shows the Total Bill and Total Payment amounts.
My try is like this: SELECT SalesNo, SUM(Price*Qty) AS TotalBill, SUM(Payment) AS TotalPayment FROM ... GROUP BY....
No syntax error or whatever found, but the result of the total amounts is incorrect.
Say the data of the respective table below:
SalesItem
No
Qty
Price
1
1
5.00
2
2
12.00
3
4
3.50
SalesPayment
No
Amount
1
10.00
2
5.00
But the result I get from the above query is:
TotalBill
TotalPayment
86.00
45.00
Total Bill should be 43.00 and Total Payment should be 15.00.
Apparently the problem is due to the fact that I and querying on multiple tables. The correct total payment amount was multiplied by the number of rows of sales items (15.00 x 3), while the correct total bill amount was multiplied by the number of rows of sale payments (43.00 x 2).
So, what is the better way of writing this query?

What is the best way to move data from Online system tro data warehouse?
I have created 3 dimension tables(product,date and customer tables) and
I wanna create fact table and get foreign keys from dimension tables.
What is the best method to do that in SSIS?
thanks
Hi,
I am new at SSIS and I am trying to create a Datawarehouse using SSIS. I have the data files as flat files I have the Dimensional Model ready on Paper and Now I need to use the SSIS for the ETL process.
I am trying to figure out how to make dimension tables in SSIS? I mean I want to create the 5 Dimension tables and then create a Fact table out of it but I cant understand where to start? Can any one tell me how we create Dimesion tables in SSIS. Like one of the dimesion tables I need to create uses 2 flat files and is like a flattened dimension, How would I create this in SSIS?
Even if there is any tutorial which shows this step by step do let me know. I would really appreciate any guidance on this.
Thanks,
Sarang
I am currently looking at the capabilities in SSIS from the point of view of an ETL developer who has worked with other products eg. Informatica, Cognos DecisionStream and one of things I note is a lack of support for dimensional hierarchies.
It appears that MS have assumed that SSIS users will automatically use SSAS.
We use Hyperion Essbase. Other sites have Cognos or Business Objects for their OLAP/BI.
I would like to be able build multi-level dimension hierarchies directly from within SSIS.
Has MS considered this for future versions?
I have created the following view:
Create view vwOrderItemTotal2
AS
SELECT ItemName, fkMenuItemID, Sum(Quantity) as [SumOfMenuITems] FROM OrderItems GROUP BY fkMenuItemId, ItemName
When I present my data in a GridView, it works fine. For example, several orders for milk are returned as a summary quantity of 26 gallons in a single row of the GridView like this:
26 Milk
Now I need to filter my data by OrderDate and Zipcode. I created this new view:
Create view vwOrderItemTotal5
AS
SELECT Orders.Zipcode, Orders.OrderDate, OrderItems.ItemName, OrderItems.fkMenuItemID, Sum(Quantity) as [SumOfMenuITems]
FROM Orders INNER JOIN OrderItems
ON Orders.OrderID = OrderItems.fkOrderID
GROUP BY fkMenuItemId, ItemName, Zipcode, OrderDate
When I present my data in a Gridview using the new view I get a GridView with multiple rows for milk where each order has its own row like this:
1 Milk
5 Milk
6 Milk
6 Milk
3 Milk
1 Milk
4 Milk
But I want the data presentation in one row for each ItemName (e.g. Milk) as with my first view. Can I adjust my new view to achieve this, or should I stick with my first view (vwOrderItemTotal2) and adjust the Select Command in my SqlDataSource (hasn’t worked yet).
I think that what I want is for the returned data to be grouped by fkMenuItemId only, but the sql server admin won’t let me create a view without including the other fields in the Group By clause. Thanks for any help provided in solving this.
I am trying to tie together tables that show quantities of a product committed to an order and quantities on hand by a location.
My end result should look like the below example.
Item Location QtyOnHandByLocation SumQtyCommitTotal
Prod1 NJ 10 10
Prod1 NY 10 0
Prod1 FL 0 0
Prod1 PA 0 0
So I can see I have 10 items in NJ On Hand and Committed to an order. 10 available in NY but not on an order. Then the other two locations have no quantities.
Below is the CTE but it produces inaccurate results. I've tried running it several different ways by playing with the grouping but have no luck thus far.
--create the temp table
Create table #SalesLine
(
Novarchar (50) not null
, LocationCodevarchar (50) not null
, QtyCommitint not null
)
create table #ItemLedgerEntry
[code]....
I am close to the desired results but can't find a way.

Hi there, my question is really simple. I want to setup an automatic task in SSIS that drops the tables in the target database and substitutes them with tables from the source database. We are talking about two or three dimension tables and one fact table. The dimension tables are pretty small. The fact table will contain, at maximum, 300,000 rows and 12 columns. I do not use delta or flag historisation btw. What tasks in SSIS would you suggest to use?
BTW I'm new to SSIS... ;-) Thanks in advance!
Hi ,
I have situation where I get data from SRC Flat file and have to load Dimensional table and also fact table, using same data flow(have no other choice since I have to unpivot some src data). Since I have to load both tables in same data flow, I have to have a way to put load ordering constraint (I know informatica allows that). Does any one have any idea on how this can be done in SSIS?
I would be really grateful.
Thanks
Dear Friends,
I created my BI Blog and I need your feedback to my post SSIS-Populating Dimension. Do you think is a good approach? In my project works perfectly!

Thanks!
Hi all,
Apologies if this has been raised in the past, but 6 hours of web searching today hasn't turned up anything!
I'd like to use the Slowly Changing Dimension (SCD) Wizard to keep track of tables in my relational database. This means 200+ tables. I don't want to step through the UI Wizard for each table. Ideally I'd like to be able to create the SCD transformation in code, but I can find no good examples for doing this. The MSDN examples here are too brief and don't allow me to expand out to the level I need.
As in any database, columns come and (very rarely, go), and having a programmatic solution to this would mean that I could be flexible and cope with these situations.
So, my question is: Has anyone implemented SCD functionality in code, or have any code examples that do this, that I might learn from. Or, any tips/pointers if I'm barking up totally the wrong tree.
Thanks in advance,

I am modelling cube in SSAS. Cube has around 20 dimensions and 6 fact tables. Some of the dimensions are common among the fact tables. e.g. Time dimension. Fact_PNL has 3 date columns for those we have 3 role playing dimensions in the dimension usages.
Another fact table has 5 date columns for them as well we have separate role playing dimensions in dimension usage tab. We have a common dimension Company which is foreign key in all fact tables. We might need to combine the data from multiple facts to get final output.
Should i create 6 role playing dimension for each of the fact table or use the same dimension for all fact tables?
Role playing dimensions should be created when we have multiple columns pointing to the same dimension ?
I created a Fact Table with 3 Keys from dimension tables, like Customer Key, property key and territory key. Since I can ONLY have one Identity key on a table, what do I need to do to avoid populating NULLs on these columns..

The report will not show the multiple records on the row group "Project" like item "Info2".
After I referred to the similar problem mentioned on this forums, I tried to use "RowNumber("Matrix1_Project")" to resolve it. But still I got the result like:

View 2 Replies View RelatedHello,
I`ve created a table in a list that is grouped by years. Result is a Report, that consists of several years (List grouped by years, each containing the table with the data of the year).
Now I want to aggregate some numbers of the table on each page (year) of the list.
The sum()-function - doesn't matter which scpoe I use - always aggregates only the values of the actual list (Year), not considering the years before.
Can anyone help?
Thanks a lot -

Hello, I€™m creating a cube with Analysis services 2000 and SQLServer 2000 that has the following structure:
The fact table has a primary key and some measures:
Fact_Table
PKFact (the primary key)
Measure 1
Measure 2
And I have some dimensions, but I€™ll put here the one of interest, this dimension has a foreign key to the fact_table, this is because it is really a €œdetail€? of the fact table, the interesting thing here is that this dimension not only has a foreign key to the fact_table, but also is a parent-child dimension:
Dimension_Table
FKFact (the foreign key to the €œPKFact€? field of the fact table)
PKId (The id of the field for the parent-child relationship)
FKParentId (the foreign key to this same table, this is, the parent of the field)
TheLevel (the data€¦)
So, if I create the cube without the Dimension_Table (of course, I have more dimensions), the cube shows the data correctly, but when I include this dimension, the data of the fact_table starts to be repeated once for each row in the dimension table (once for each row that has the relation PKFact €“ FKFact of course), Somebody knows how I can avoid this data being repeated? I€™ve tried a lot of things but none works.. Please help!!
Thanks in advance.

Ok so I need to write a query that finds the lowest grade out of a group of students (by a class number), and identifies it by a student id #.
Here's what I'm trying:
select min(gr.grade), gr.stu_id
from dbo.class cl, dbo.grade gr
where (cl.class = 2) and (abs(cl.stu_id) = abs(gr.stu_id))
group by gr.stu_id
but unfortunetly it returns the lowest grade for each student in class 2, and not the single lowest grade in class 2 and the stu_id (student ID).
I'm new to SQL and could really use the help.
Thanks

We have a set of cubes and dimensions, and we're experimenting with data mining against the cubes (primarily for forecasting applications). We have a custom time dimension (which we call calendar), not generated by the BIStudio wizard. The dimension has year/month/day/hour/... attributes. But when I try to add this Calendar dimension to the mining structure as a nested table using BI studio, it only shows the Year attribute, not the others. Other dimensions seem to show all the attributes.
Is there something we've done wrong in defining our time dimension? What determines which attributes show up as available for selection in BI studio?
