How To Populate Fact Table With Date Id From Date Dimension
Dec 28, 2007
can someone help me with th best way to look up a date in date dimension and populate the date id in fact.
in the source date is dd/mm/yyyy
and in date dimension columns are date id , year , quarter , month, day
I cannot create a measure that returns results for dates that do not exist in the fact table despite the fact that the components included in the measure contain valid results for these same dates.Creature a measure that counts the number of days where the "stock qty" is below the "avg monthly sales qty for the last 12 months" (rolling measure).Here is the DAX code I have tried for the measure (note that filter explicitly refers to the date table (called Calendar) and not the fact table):
Below you can see the sub measures (circled in red) are giving results for all days in the calendar.Highlighted in yellow are dates for which the StkOutCnt measure is not returning a result. Having investigated these blank dates, I am pretty confident that they are dates for which there are no transactions in the fact table (weekends, public holidays etc...).why I am getting an "inner join" with my fact table dates despite the fact that this is not requested anywhere in the dax code and that the two sub measures are behaving normally?
Now I have to populate the fact & dimension tables by writing sql scripts. Now I have already populated the dimension tables by writing sql script, But I have to populate the fact table taking into account, here I am facing problem in wriring sql script
(i) unit_price is taken from the book base table with reference to the isbn (ii) sales_quantity is taken from the order_detail.quantity with reference to table cust_order(via orderid & orderdate) (iii) discount_price is determined dependent on the quantity. if the quantity > 20 then discount 20 %(i.e discount_price = 0.8 * unit_price). if quantity < 10, no discount i.e normal price. if quantity between 10 and 20, discount 10%. Note that the quantity is determined based on each order of each customer, thus if the same book appears at multiple positions in an order, those positions shall be grouped together. This could happen because the pk of the order_detail table is order_id + item no, not order_id + isbn (iv) sales_amount is sales_quantity * discount_price
I have below tables in my power pivot.Fact 1 & Fact 2 - connected directly to Mainframes - Data is from the same table broken up due to size of the data.Date Table - Relation ship between both the fact tables.How do i create a summary pivot to get the number of tasks that have been completed in each month.
Now I create datawarehouse for my client, I have SSIS a lot for ETL process, I a problem that some fact table need to be updatetable and there is a lot of data of this, I need some efficent way to load this data to data warehouse. I have read your article about SCD in SSIS (Slowly Changing Dimensions in SQL Server 2005). I think the purpose of SCD for Dimension table. If I have some fact table that need rows to be updatetable can you give me an example, best practice, the efficient way or fastet way to load fact table that can be updatetable? If you have link or link about this problem please reply my email. Thanks My datasource from ORACLE and my datawarehouse in mssql2005
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?
I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.
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..
As u can see there is two company references in my fact table, and the schema is in snowflake. My customer requirements state that the Contracts' amounts can be aggregated/filtered for/by, ServiceProviderCompany, its city/profession or ClientCompay, its city/profession.
First thing came in to my mind is to dublicate whole dimension structure (one for serviceproviders, one for clients), which i thought that there should be another way around?
we have a problem with "one-to-many relations between fact table and dimension table". Take the example of table "LOGGEDFLAW" which is related one-to-many to the table "LOGGEDREASON. "LOGGEDFLAW" includes the column "FLAWKEY" and "LOGGEDREASON" includes the column "REASONKEY" and essentiallay the column "FLAWKEY" as foreign key. Now assume that we have the following records in there:
Now assume, that "LOGGEDFLAW" is the facttable and "FLAWCOUNT" is the measure with the source column "FLAWKEY" in which we want to count the number of FLAWs. As you see in the example the number of FLAWs is 1 for "FLAW1" and "FLAW2". Microsoft Analysis Server generates the value of 2 for the number of FLAWs "FLAW1" because of the one-to-many relationship to the table "LOGGEDREASON". In the attached ZIP File you find :
- a MDB File with the described example - a screenshot from the cube constructed in AS - a screenshot from the result table generated with AS.
The question: How is it possible to calculate the measure "FLAWCOUNT" correctly, ignoring the records generated by the one-to-many relationship?
In my data modell I have defined the 2 tables "Person" and "Category":
Table "Person" ---------------- [PersonID] [int] IDENTITY(1,1) NOT NULL [CategoryID] [int] NOT NULL [FirstName] [nvarchar](50) [LastName] [nvarchar](50)
Table "Category" ---------------- [CategoryID] [int] IDENTITY(1,1) NOT NULL [CategoryName] [nvarchar](50)
Now I like to read my first row from the source and lookup a value for the CategoryID "sailing". As my data tables are empty right now, the lookup is not able to read a value for "sailing". Now I like to insert a new row in the table "Category" for the value "sailing" and receive the new "CategoryID" to insert my values in the table "Person" INCLUDING the new "CategoryID".
I think this is a normal way of reading data from a source and performing some lookups. In my "real world" scenario I have to lookup about 20 foreign keys before I'm able to insert the row read from the flat file source.
I really can't belief that this is a "special" case and I also can't belief that there is no easy and simple way to solve this with SSIS. Ok, the solution from Thomas is working but it is a very complex solution for this small problem. So, any help would be appreciated...
I have a large flat file that comes to me. I first import the flat data in to a SQL table for ease of use. Then i put it into a more permanent table with the proper references to dimension tables. I want to build a dimension table out of information from my flat file. I have a dimension table with columns, [Org Client], and [Client#] where [org client] is the name of the client. Both of these columns appear in my flat file but i want to use only the client# in my permanent table. How extract distinct values of client # and [org client] into a dimension table?
My idea was to select distinct values of client# and use some type of foreach loop to go through each client# and use a query to select the TOP(1) values of [org client] where client# = x. Would this work and if so how do I go about setting this up?
I'm really hoping there is a simpler way than this. Thank you all for your time.
We are trying to do some utilization calculations that need to factor in a given number of holiday hours per month.
I have a date dimension table (dimdate). Has a row for every day of every year (2006-2015)
I have a work entry fact table (timedetail). Has a row for every work entry. Each row has a worked date, and this column has a relationship to dimdate.
Our holidays fluctuate, and we offer floating holidays that our staff get to pick. So we cannot hard code which individual dates in dimdate as holidays. So what we have done is added a column to our dimdate table called HolidayHoursPerMonth.
This column will list the number of holiday hours available in the given month that the individual date happens to fall within, thus there are a lot of duplicates. Below is a brief example of dimdate. In the example below, there are 0 holiday hours for the month of June, and their are 8 holiday hours for the month of July.
I have a pivot table create based of the fact table. I then have various date slicers from the dimension table (i.e. year, month). If I simply drag this column into the pivot table and summarize by MAX it works when you are sliced on a single month, but breaks if anything but a single month is sliced on.
I am trying to create a measure that calculates the amount of holiday hours based on the what's sliced, but only using a single value for each month. For example July should just be 8, not 8 x #of days in the month.
Listed below is how many hours per month. So if you were to slice on an entire year, the measure should equal 64. If you sliced on Jan, Feb and March, the measure should equal 12. If you were to slice nothing, thus including all 15 years in our dimdate table, the measure should equal 640 (10 years x 64 hours per year).
My question here is as the dimension has SCD type 2 on it and every time when there is a change the persn_key gets a new key value but the fact table still points to oldest key.how to update the surrogate key on fact table to the current key value? As per the requirement fact surrogate key must be pointing to current active record on the dimension.
The field OrderDate contains BOTH Date and Time information. What I want to do is populate the fields (in bold above) from the OrderDate field... I have tried all that I could think of but nothing works. The last and the best try that I gave was the {B}following[/B] but that too does not work. Can you PLEASE help. Many thanks in advance:
Insert ORDERS (OrderDateONLY, OrderDayName, OrderMonth, OrderDayOfMonth, OrderWeekofYear) select d, datename (dw, d), datename (mm, d), Year (d), datepart (ww, d) from (select convert (char (8), OrderDate, 112)as d from ORDERS ) as x

Hi, I need to create a SSIS package for following usage:
I have a folder called c: est. Every month, I copy a file with following format testMMYY.txt. (Month Year) from a client (A) for vendor B. I have a sql table which contains filemonth(, clientname and vendorname. How can I create a SSIS package to detect any new files, if any, and populate the month and year into file month, and populate clientname and vendorname.
I would like to return the nearest date of Table B in my table like for
ID W001 in table B should return ID A002 CreatedDatetime: 2014-06-03 20:05:48.000 ID W002 in table B should return ID A004 CreatedDatetime: 2014-06-04 01:05:48.000
I am in a situation to slice a fact in two date dimension .. my <g class="gr_ gr_73 gr-alert gr_spell ContextualSpelling ins-del multiReplace" data-gr-id="73" id="73">sql</g> code is like this
select count(1) from fact_table where end_date >=(selecteddate on filter) and startdate <=end_date .
The common date dimension is Start date. and the filter will be only on <g class="gr_ gr_168 gr-alert gr_gramm Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="168" id="168">end</g> date.
Below is the code so far
<g class="gr_ gr_228 gr-alert gr_tiny gr_spell ContextualSpelling multiReplace" data-gr-id="228" id="228">i</g> did, but <g class="gr_ gr_229 gr-alert gr_tiny gr_spell ContextualSpelling multiReplace" data-gr-id="229" id="229">i</g> am not finding how to filter the start date <=end_date
with member [Measures].[X] as
Sum( {[EndDate].[YQMWD].currentmember:NULL}, ([Measures].[Count])) select [Measures].[X] on 0 , [EndDate].[YQMWD].year.members on 1 from Cube
What is the trick I can put so that I can filter those data where start date <=selected end date ....
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?
I would like to create calculated measure which should give me closing holdings at all levels(week ,Month,Quarter and year levels.) whichever i pull in the browse pane.
Below calculated measure would show the holdings for whatever the level you have specified.
([Measures].[Holdings], ClosingPeriod( [DIM BI DATE].[Calendar].[WEEK], [DIM BI DATE].[Calendar].CurrentMember ))
But this measure shows the value for only week attribute.
for month,([Measures].[Holdings],ClosingPeriod( [DIM BI DATE].[Calendar].[Month], [DIM BI DATE].[Calendar].CurrentMember ))
But my aim is to create a calculated measure to give closing value for any level.

We have a date dimension which spans till 2099 and there are future projection numbers (under measures). I want to limit the data for Future projections only to 5 years from today by default. Is there a way to do this with in the cube. I understand that this can be done using MDX but since we use excel to view the data from the cube it needs to be controlled with in the cube.
