Missing Dimension Member During Fact Load
Aug 15, 2007
I'm putting together a Kimball method SSIS package. My factSales table has an OrderRep key. If a match isn't found in the dimRep table I am inserting a dummy dimRep row and going on. That seems to be working.
My question is what do I do when the OLTP sales row has NULL for the OrderRep. This is possible; every sale does not have to have an order rep. My package is seeing that as a non match and trying to create a dummy row in the dimRep table for every NULL. I really don't want to do this. I can trap for the NULL rep and convert it to "unknown" or something but then the program would still create a single row in the dimRep table for unknown. Is that the best way to handle this? Or is there a way to trap for NULL and ignore the entire lookup process? A conditional split before every key lookup?
I have about 5 or 6 other dimension tables that will have the same NULL possibility.
Thanks.

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

Hi All,
I am just curious to know how I can load data from a data warehouse to an Analysis Service Cube (both to the fact tables and dimensions).
Does any body have some way to achieve this?
I appreciate if any body provide me a good material which describe this scenario.
Sincerely,
--Amde

A few questions:
1) We have numerous fact tables with surrogate keys which reference just one dimensional surrogate key. How does this work?
2) Are the ‘facts’ feeding data TO the ‘dimensions’ (back end warehousing)? Or are the ‘Dimensions’ feeding facts to the ‘facts’ tables for lookups!?
Nb: Im very inexperienced at database design.
Im really also using this thread to get contacts for future harder questions!
Thanks kindly

Hi
Analysis manager won’t let me create dimension unless fact table filed has value init. Other words, how do I create MT dimension(dimension without member)

I have a fact table that has terminations. Fields include EmployeeName, TermDate, TermReason, and HireDate, et al.
I need to make EmployeeName available to drillthrough, and since it's a varchar field I can't make it a measure, so it has to be a dimension attribute. My question is, should I leave the fact table as it is and use SSAS to create a dimension that contains only EmployeeName and the link to TerminationID? Or should I redesign the OLAP tables so that EmployeeName is in a separate table?

Dear all,
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

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 have a fact table with few flag columns.
What is the best way to bring them to dimension?
Do I need to create dimension(dummy) from fact table for each flag or all flags in single dimension?

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!

I've got a dimension built from a fact (whatever that's called?) ... it's a date interval field, i.e. 0-5 weeks, 6-10 weeks 11+ weeks. How do I sort these members in the respective order? Looks like this currently:
The problem lies in the fact that I don't have any secondary attributes to order it by, i.e. it's not a physical dimension where I can use a key for the 3 members. I was hoping I wouldn't need to create a separate dimension to get round this.

I am Using following MDX Query to get the data for max date in the Dimension. But every time I am passing date key to dimension to get data. How to automatically get the Max available Level member for that dimension.In this case I am passing 20150429 to every line instead i need to get that automatically.
SELECTÂ
(
{
[DimDate].[HierYQMD].[Date Key].&[20150429],
{[DimDate].[HierYQMD].[Date Key].&[20150429].PARENT.PARENT.PARENT.LAG(4):
[DimDate].[HierYQMD].[Date Key].&[20150429].PARENT.PARENT.PARENT},
[code]....

hi all,
I was wondering if it is possible in SSAS 2005 that a calculated member is based off of an (integer) dimension attribute and another (integer) measure (let's say a multiplication operation) ?
If there a trick on doing so? other than stuffing the (integer) dimension attribute back in the fact table, as an measure?
thx much,
Cos

I'm loading a fact table that has several geographic attributes - some are at the state level, some are at the county level, and then some are drilled farther in that that. I understand the basic concept of the dimension with the ragged hierarchy, but unsure of how to load to the fact table using lookups based on these geographic units. For example, if my geographic dimension contains 200 records for the state of Wyoming, basically a record for each fine-grain place (i.e. city/town), then how do I go about doing a county lookup. Wyoming only has 23 counties, but because of the repetitive nature of the dimension attributes that are not at the finest grain, I'll get more records in the lookup than I need. This activity repeats of course while I move up the geographic scale to state, then country. How do I configure/fill my dimension to handle these differing scales of data?

I want an MDX calculated dimension member, (with no measure specified in expression, so that any related measure can be used in a query/browse), and that accomplishes either one of the following:
Ideal: To calculate Median values on every level of a user hierarchy
If "Ideal" is not possible, then "Acceptable" is: To calculates Median values on one or more levels OTHER than the highest level.

<SQL Server 2008 R2>
I created a Time table using BIS. I found that the default naming of time members is too long and redundant.
For example, the wizard generated "Fiscal Calendar 2015", "Fiscal Quarter 1, 2015", etc. However, shorter expression like "FY2015", "FQ1 2015", etc would be enough for me.Â
Is it possible to change the default naming rule, or does SSAS works correctly if I update the Time table values using SQL?

Hi all,
Maybe someone here can help me out: I have a Kimball type II dimension, where i track changes in a hierarchy. Each row has a RowStartDate and RowEndDate property to indicate from when to when a certain row should be used.
Now i want to load facts to that table. So each fact will have a certain date associated with it that i can use to lookup the right Id (a certain SourceId can have mulitiple integer Ids when there are historic changes) and then load the facts.
Is there a building block I can use for that? I could do this with SQL scripts but the client would prefer to have as much as possible done in SSIS. The Lookup transformation will only let me specify an equal (inner join where A=B) join, but i need equal for one column (SourceId) and then >= and <= (RowStart and RowEnd) to find the right row version.
Any ideas? Thanks in advance,
John

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 have a model contains fact of account revenue , a time dimension and scd of account.
the scd (type 2) is changing when an account get a new color.
when i queries the model by PowerPivot i sometimes get wrong color for an account in a date priod , for example , I would expect to see color 3 for account 1 at 04-06-2010 , But instead I see  color 1 - as you can see in the picture bellow.
FACT , SCD :
Result
i process all , deploy , mark dim_time as date dim , and i still cant find the error.

I am developing a BI solution on SQL Server 2008 R2 and how to handle multiple referances to the same dimension from a fact table!
Here is the scenario;
Fact_Contracts (# M)
ServiceProvider_CompanyID, Client_CompanyID, Amount_USDÂ
Dim_Company( hundreds)
ID, CityID, ProfessionID, CompanyName
Dim_City
ID, CityName
Dim_Profession
 ID, ProfessionName
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?

I have a Fact table that contains several degenerate string values that I have pulled into a Fact Dimension.
When I browse the cube and cut one of the measures by an attribute from the Fact Dimension, I am getting incorrect data.
In other words, when I query the fact table directly via SQL and apply the same filters, I see the data I am expecting to see. But cube browse with same filters yields different results.
How can this happen since the fact dimension has a 1:1 relationship with the fact table.
I do have the Dimension Usage configured properly.
Is this an aggregation thing? Attribute key thing? What am I missing?

Hi
A very basic MDX question. Using the following from AdventureWorks as an example:
Code Snippet
WITH MEMBER [Measures].[Big Cities]
AS
(
[Geography].[City].&[New York]&[NY]
, [Measures].[Internet Order Count]
)
SELECT
[Measures].[Big Cities] ON COLUMNS
, [Customer].[Total Children].Children ON ROWS
FROM [Adventure Works]
How would I re-write the [Measures].[Big Cities] calculated member so it included both [Geography].[City].&[New York]&[NY] and [Geography].[City].&[Los Angeles]&[CA]? Assuming there is no logical connection between these members, and that they are non-contiguous. Also, in my real example, I cannot move [Measures].[Internet Order Count] to the WHERE clause, it must remain within the calculated member.
Thanks,
Julia.

I have built a fact table and few dimension views in Datamart with the aim of creating a Cube.
On the Fact table I have added a CASE Statement with the following threshold for Premium due amounts:
CASE WHEN....
'Due_0-1_Month'
'Due_1-2_Month'
'Due_2-3_Month'
'Due_Over_3_Months'
'Overdue_0-1_Month'
'Overdue_1-3_Month'
'Overdue_3-6_Month'
'Overdue_Over_6_Months'
...END
I then created a Dimension to link this to:
CREATE VIEW...
Select 'Due_0-1_Month' as Ageing_Threshold
union all
Select 'Due_1-2_Month'
union all
Select 'Due_2-3_Month'
[Code] ....
I was successful in processing the cube, however the problem is everytime I drag the dimension on the columns field in Pivot tables the Thresholds start to break up the other amounts that I have on display like Acquisition Costs, Tax amounts. I am only interested in showing the breakdown of Premium amount measure by the Threshold dimension.
somehow 'Hide' or 'prevent' the Threshold dimension from breaking down the other measures on the Pivot and only breakdown the amounts for Premium?
how I should structure my tables in SQL or any MDX queries to resolve this.

Have a need to let the user select the year and month to use for filtering results from an MDX query that populates a report.I think all I should need is a list of years and a Month name / number.What would the filter look like if say I had a Date dimension that included the year number in a 4-digit and month in a 2-digit number? In TSQL it would be something like ... where Month = @month AND Year = @year...How do I get a distinct list of member values for the month numbers from the Date dimension?

Hi,
I defined several calculated measures in my cube. In Report Designer, i want to filter data depending a calculated measure.
Some caluclated measures are missing properties like value or ismissing. Anybody a hint, why these measures dont provide the properties, as for that filtering or hiding is not possible.
In AS every property is the sam for all calcs and the leaking calcs dont have difficult expressions (IIF(measure<0,measure/measure,0.0)
Thanks in advance

Hi all,
i have a fact table which loads through package,when
i m trying to load this table by running the package,i m truncating the
fact table and loading the fresh data,instaed of this without
truncating the fact table i have to implement the incremental logic in
this.
For this i can use SCD or Conditional split,but problem
here is i have many source tables to load this fact table,so its
very difficult to trace the changes in different source tables.

I saw a previous request for help, but I did not see a solution (other than deleting and re-initializing the dump.
I'm copying a database from one server to another and I repetedly get this error when I try to restore from the .bak file I create on backup. The host machine for the database is a workstation (no RAID). The Destination does have RAID, but is funtioning properly (according to the SysOps and in testing file copies). I've tried copying the .bak file to several different drives several different times and I get the same error. I also tried to back-up a database on the Destination server and restore the .bak file to a newly created database and I get the same error.
Anyone solve this problem?

Below is code that I have aquired from both the SQL6.5 Books online and a VB5 book. The problem is that when I run this code it returns back the error Method or data member not found. OK I have been to Projects References and made sure that both the Microsoft RemoteData object 2.0 and Remotedata control 2.0 where both included in my project.
The Remotedata control works great, however it does not allow me to Add data and Remove Data.
Am I missing a Reference file?
Do I have the correct version of Remotedata objects?
Private Sub Command1_Click()
Dim cn As rdoConnection
Set cn = rdoEngine.rdoenviroments(0).OpenConnection("sqlser ver")
Dim mysql As String
mysql = "select cuscode from customer where cuscode = '1122'"
Dim myqy As rdoQuery
Set myqy = cn.CreateQuery("myqy1", "")
myqy.SQL = mysql
Dim myrs As rdoResultset
Set myrs = myqy.OpenResultset(rdopenfowardonly, _
rdConcurReadOnly)
While Not myrs.EOF
Debug.Print myrs(0)
myrs.MoveNext
Wend
myrs.Close
myqy.Close
End Sub
Thanks in advance.

I have dimension data like thisÂ
persn_key  persn_id  address   is_active  updated_date
1 Â Â Â Â Â Â Â Â 10 Â Â Â Â Â Â NYC Â Â Â Â 0 Â Â Â Â Â Â 2015-11-04 14:19:54.817
2         10      Chicago    1      null
and Fact table like
fact_key  persn_key units_purchased
1 Â Â Â Â Â Â Â Â 1 Â Â Â Â Â Â 10
persn_key is the surrogate key between tables.
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.
