Fact to Dimension ratio

Is there a t-code to check Fact and Dimension table ratios other than doing an RSRV check?
Thanks

hi,
I think you can go to se16, check there how many records each table consist of and do calculations on your own.
but why you do not want to use rsrv?

In Answers am seeing "Folder is Empty" for Logical Fact and Dimension Table

Hi All,
Am working on OBIEE Answers, on of sudden when i clicked on Logical Fact table it showed me as "folder is empty". I restarted all the services and then tried still showing same for Logical Fact and Dimension tables but am able to see all my reports in Shared Folders. I restarted the machine too but no change. Please help me out to resolve this issue.
Thanks in Advance.

Best practice when FACT and DIMENSION table are the same

Hi,
In my physical model I have some tables that are both fact and dimension table, i.e. in the BMM they are of course separated into Fact and Dim source (2 different units) and it works fine. But I can see that there will be trouble when having more fact tables and I e.g. have a Period dimension pointing to all the different fact tables (different sources).
Seems like the best solution to this is to have an alias of the fact/transaction table and have 2 "copies" of the transaction table (one for fact and one for dimension table) in the physical layer. Only bad thing is that there will then allways be 2 lookups in the same table when fetching data from the dimension and the fact table.
This is not built on a datawarehouse - so the architecture is thereby more complex. Hope this was understandable (trying to make a short story of it).
Any best practice on this? Or other suggestions.

Id recommend creation of a view in the database. if its an oracle DB, materialised views would be a huge performance benefit. you just need to make sure that the MVs are updated when the source is updated.

I want to desing a fact and dimension(s) for this parent & Child tables.
Please help me what are the things I have to keep in mind when desingning datawarehouse fact and dimension tables?
Thanks,

Hi, any update on this?

Delete Fact and Dimension Tables

Hai All,
Small question! When deleting data from info cube, it asks whether to delete just Dimension table or both fact and Dimension tables.
What is the difference between these two?
Thank you.

Hi Visu,
The dimension table will contain the references to char value by way of SID and DIM ids, whereas the fact table will contain the number (of key figures). If you delete just the Fact table, the numbers go away, yet the DIM ids remain intact, so reload is faster. But if you are convinced that this data is not correct either, or you want a clean slate to strat reload again, then delete both Fact and Dim tables. Then when you reload, the DIM ids will be created again.
Hope this helps...

Unable to Create Fact and Dimension tables from the Tools menu in EIS conso

How to have fact and dimension which are not joined in same report

Hi All,
suppose we have 2 dimensions and 1 of them is joined to fact but we want to pull both these dimensions along with fact and fact column shows null but we dont want that .how can we have 2nd dimension which is not joined to fact in the same report .Actually i have a column called equipment schedueled time and it can be shown only with equipment dimension but I want to pull both equipment,geography and equipment scheduled time in report if I do it now it shows equipment scheduled time as null because its not joined with geography dimension.I want even if the geography dimension exists it should show the value of equipment scheduled time .
Can someone please help me.
Thanks in Advance

Hi ,
Can you please tell me what are fact and dimension tables of your requirement.If you want display the data from 2 dims and a fact table ,you have to establish the joins between facts and dimensions.
mark if helpful/correct...

Facts and dimensions joins

Hi,
Can we use three fact tables in rpd and not join them? We have three facts and four dimensions. All the four are common dimensions to the three fact tables. So in the physical joins can we just join the facts to the dimensions? will it be accepatble if we do not have a join between fact tables. Is it necessary that all the tables (fact and dimensions) need to be joined to some tabler? Can we leave the joins between the facts which are not necessary? Please advice.

We do not do joins between fact tables, the joins between facts will be happened through dimensions (conformed dimensions).
In your case the 4 dimension will act as an conformed one.
Is it necessary that all the tables (fact and dimensions) need to be joined to some tabler? You cannot have a table in BMM which is not joined to any other table.
Can we leave the joins between the facts which are not necessary?Yes, Dim1 - fact1 -Dim 2 in this fact 1 is connected with Dim1, Dim2 and there is no relationship for fact1 with Dim3 so we don't join it.
Dim1,Dim2,Dim3 is joined with fact2 in this case Dim 1 and Dim2 will act as conformed dimesion between fact1 and fact2, where as dim3 will be a non conformed dimesion.
Thanks,
Vino

Join multiple facts and dimensions for reporting issue

Hi,
I have a report requirements and need to use multiple fact tables and unconformed dimensions as described below
Fact table: F1,F2,F3
Dimensions tables: D1.....D9
F1:(joined to) D1,D2,D3,D4
F2::(joined to)D1,D2,D5,D6
F3::(joined to)D1,D2,D7,D8
D7::(joined to)D9,D8 (dimension D7 joined to two other dimensions D9 and D8
I'm trying to use columns from almost all the fact and dimension tables but getting "Unable to navigate requested expression. Please fix the metadata consistency warnings."
Repository is consistent and no errors and warnings.
How can I configure the repository to develop reports using all fact tables and dimensions?
Appreciate for your help.
Thanks
Jay.

How to design many to many relationship in the fact and dimension

There is a problem in my project what is the subject.And i wanna know how to implement in owb.I use the warehouse builder 10. Thanks.

You may design and load whatever db model you want to.
But If you set a unique key, you may find some integrity issues. I wouldn't do a many to many relationship between facts and dimensions. This could cause you lots of headaches when users start to submit queries using this tables. You'll probably face performance issues.

DWH: how do you analyze fact and dimension tables

Hi,
I was wondering how you analyze your fact and dimension tables.
Our fact table is partitioned per month. Each partition contains 4M rows and is 270 MB large. We are using 9 dimensions, 6 have about 50'000 rows (2MB), 1 about 1M rows (50MB) and 2 about 3M rows (200MB). All tables are compressed. The version of Oracle we are using is 9.2.0.5.
What I was wondering is how you would, using dbms_stats, analyze the fact and dimension tables. Which percentage would you analyze? On which column would you build histograms?

nope, but i could copy-paste the URL or I could copy-paste the entire thread from the other forum. Id did the one that made more sense to me.

SQL08 Need example of creating AND using a Fact (degenerate) dimension

Can someone post a link to some examples of setting up and using a Fact (degenerate) dimension. Ive got the SSAS 2008R2 Adventureworks DW project setup and I see a few Fact dimensions in there, but id like some descriptions to go along with this or
something similar.
My scenario:
Orders - attributes include : Order#, OrderStartDate, SalesPerson, BusinessType, MarketType
OrderTransactions - attributes include: OrderKey , TransactionAmount, TransactionType, TransactionDate, AccountKey
Description:
Its more or less the typical Order > Order Detail type scenario, with the addition of Orders have some additional attributes.
So I want to be able to measure on for example:
Order counts - broken down by BusinessType and MarketType , and then within a date range
Revenue - which will be totals of transaction amounts, again grouped by BusinessType and MarketType, but also be able to drill down to see the related Order#

Hi Shiftbit,
According to your description, you need some examples about create and use degenerate dimensions, right?
Degenerate dimensions, also called fact dimensions, are standard dimensions that are constructed from attribute columns in fact tables instead of from attribute columns in dimension tables. Here is document that describes how to create and use degenerate
dimensions step by step, please refer to the links below.

Left outer join on Fact and dimension table.

Hi all, I have a fact F with account number and few measures as columns.
I also have a dimension D with account number, account name columns.
Few account numbers from Fact doesnt exist in Dimension D , but they need to show up in the report though.
How do I left join Fact and Dimension D in RPD?
I have this report where I need to show Account Number, Account name, measures.
If D doesnt have certain account numbers, I need to convert that account number from F as string and show it in the report in account name column.
Can you pls help.

Ok. I tried this:
Driving table : Fact, Left outer join -- didnt work.
Driving table: Dimension D left outer join -- didnt work either
In either the case, I see physical query as D left outer Join on Fact F. and omitting the rows.
And then I tried this -
Driving table: Fact, RIght outer join.
Now, this is giving me error:
Sybase][ODBC Driver]Internal Error. [nQSError: 16001] ODBC error state: 00000 code: 30128 message: [Sybase][ODBC Driver]Data overflow. Increase specified column size or buffer size. [nQSError: 16011] ODBC error occurred while executing SQLExtendedFetch to retrieve the results of a SQL statement. (HY000)
I checked all columns, everything matched with database table type and size.
I am pulling Fact.account number, Dimension.account name, Fact.Measures. I am seeing this error each time I pull Fact.Account number.

Fact and Dimension Linking

Hi,
Is it possible to link Fact and Dimension tables with two conditions using OR.
I have one dimension table for Customer Sites where Site_Use_ID (Pk).
But in my Fact table, Bill_To_Site_Use_ID and Ship_To_Site_Use_ID
SITE_USE_ID = BILL_TO_SITE_USE_ID OR
SITE_USE_ID = SHIP_TO_SITE_USE_ID
So, I need to join Customer sites Dimension with Fact and it is possible with OR condition. How can I specify these two condition while linking..
Thanks in Advance,
-Vency

Hi Daan Bakboord,
I tried those things.
I have already tried to create complex join in Physical Layer but unfortunately it is saying that "The column 'SITE_USE_ID" is used more than once". So, I am unable to create complex join.
Coming to creating Alias Table.. If I create Alias for that table then I need to show both the tables to the user (in Presentation Layer) so that he/she can select BILL_TO from one and SHIP_TO from another table.
But I am trying to get it with only one Table.
Thanks for giving reply,
-Vency
