Multiple fact tables using one measure

Hi Experts,
Multiple fact tables using single measure .For example Measure name is amount . This measure is using 5 fact tables. By using this info , i have to create bmm layer document . In bmm layer documents columns are like logical table name ,column name, logical sourc name . could you please help me out to draft the document ?

Hi ,
My question is five fact tables are there, day level two different fact tables , period and week fact tables are there .
Above all tables are using single measure . how to design these fact tables with measure in bmm layer ?
Please kindly give reply .
Thanks in advance.

Join multiple fact tables and dimensions and use all tables in report 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.

So you want me to convert snowflake schema to star. does it solve my problem? individual star queries are working find but when I query multiple stars together getting inconsistency errors. I removed content tables dim level totals for unconformed dimensions in logical fact LTS and set level for measures at total level for unconformed dimensions. it is still in progress and need to test.
Thanks

Multiple 'logical joins' between a fact table and one dimension table

It appears that one cannot create multiple ‘logical joins’ between a fact table and one dimension table in OBIEE using the Oracle BI Administration Tool. For example, considering a Business Model with a dimension table TIMES and a fact table FACT containing START_TIME and END_TIME, we would like to create separate logical joins from FACT to TIMES for the START_TIMEs and END_TIMEs? Obviously, the underlying foreign keys can be created, but as far as I can tell the Oracle BI Administration Tool doesn’t support this. The workaround would be to replicate the TIMES table, but that’s ugly.
I seek an alternative approach.

Try this. Create an two aliases for the TIMES dimension (Start & End) in the Physical Layer and then remove foreign key to the "Parent" Times dimension. Create the Foreign Key in the Physical Layer to the new aliases and then create the complex joins in the BMM Layer to the new aliases as well. This will allow you to present both dates within the same table in the Presentation Layer. Not the most elegant solution but it works.

Can a measure map to multiple fact tables

Hi Experts,
Can A Measure in an Universe map to multiple fact tables? For example, we have sales detail table by day and store and product, and have sales summary table by day and region and (product) department. We like to create a measure to map to both detail table and summary table. When I run query includes store and product, the query will automatically use the sales detail table; and query can automatically choose the summary table when it only includes region and department. Our database table could be in Teradata and Oracle. Can we achieve it and how? If a measure can't achieve this (dimension awareness), what the other option we can have and how to do it?
Thank you,
Richard

Hi Sion,
After I make the tables incompatible with the dimension objects on different levels, the measure can point to the right table if my query only include Store and Product or only include Region and Department. But in some scenario, the business could ask to include both Store and Region or Item and Department in same query. The current approach doesn't work on this further request. In our database, we have store table including Region with other higher level organization information, Product table including Department with other higher level product information, and we also have separated Region table and Department table. Could we make the objects more flexible u2013 query will be against aggregation sales table if dimension objects in query are only on higher level and will against detail sales table if some of dimension objects are on high level and some on low level?
Many thanks,
Richard

Adding data to multiple tables using one form in Access 2010?

Hi All,
I have a access database with two tables and I want to create a single form to enter data into that tables.
How to adding data to multiple tables using one form in Access 2010?
I don't have to much knowledge of access database?
Please help me
Thanks
Balaji

You really don't enter identical data into 2 tables. You enter dat into one single table, and then you have an unique identifier that maps to another table (you have a unique relationship between two tables).
Maybe you need to read this.
http://office.microsoft.com/en-001/access-help/database-design-basics-HA001224247.aspx
Think about it this way... What is you update data in 2 tables, and then the data in one of those tables changes, but the data in the other table does NOT change. WHOOPS!! Now, you've got a BIG problem. For instance, you have a customer
named Bill Gates. In one Table you update Bill's address to 1835 73rd Ave NE, Medina, WA 98039 and in the other table you accidentally update Bill's address to 183 73rd Ave NE, Medina, WA 98039. Now you have 2 addresses for Bill. Why would
you want that??? Which is right? No one knows. If you have one address, you just have to update one address and if there is a mistake, you just have to update one address, but you don't have to waste time trying to figure out which is right
and which is wong...and then update the one that is wrong.
Post back with specific questions.
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Multiple fact tables, aggregation and model problems

Hi,
I am developing a OLAP Application with 2 dimensions (product,location) and a few measures (sales_qty, sales_value, sale_price, cost_price, promotion_price, average_market_price, etc). I also have a BiBean Crosstab to explore the data.
I'm having the following problems:
- The measures are in different fact tables.
When using cwm2_olap_table_map.Map_FactTbl_Measure, I can only map the measures from the first fact table, the others return "Exact fetch returns more than the request number of rows".
- The 'price_' measures shouldn't aggregate to higher levels of the dimension hierarchies. I have changed the default aggregation plan, but in the crosstab data is still shown in the higher levels. Is there any way to show N/A in levels that I don't want to aggregate?
- How can I add a calculated field that is the result of a complex set of business rules (with IF/THEN/ELSE statements and calls to existing oracle functions) and precalculate it during batch?
Thanks,
Ricardo

Keith, thanks for the quick answer!
Some questions regarding your comments:
1) The measures are in different fact tables
- My application will show all the measures in the same report. My question is, will performance be affected by creating separate cubes or creating one cube? I believe that if I don't use an AW, it shouldn't, but I will have an AW. Performance is the main reason why I'm using Oracle OLAP. I need fast access to measures in different fact tables in one report. Those measures will be used in complex calculated fields, and probably in 'what if' analysis.
2) When using cwm2_olap_table_map.Map_FactTbl_Measure, I can only map the measures from the first fact table, the others return "Exact fetch returns more than the request number of rows".
Here is the complete script I am using to create the cube:
execute cwm2_olap_cube.Create_Cube('OLAP','CUBE_REL_3','CUBE_REL_3','MY_CUBE','MY_CUBE');
execute cwm2_olap_cube.add_dimension_to_cube('OLAP', 'CUBE_REL_3','OLAP', 'DIM_STORE');

The error is in the cwm2_olap_table_map.Map_FactTbl_Measure command for the first measure of the second fact table. Am I doing something wrong?
Regarding issues 3) and 4), I will follow your sugestions. I'll get back to you on this later.
Once again, thanks for the help, it is being most helpful.

Joins with multiple fact tables

Hi Experts,
i have one doubt in joins
we have two dimensions D1 and D2,
D1 is having A1 and A2 columns
D2 is having B1 and B2 columns
two facts F1 and F2 these are joined like D1 to F1 D1 to F2 and D2 to F1, D2 to F2
D1----->F1
D1------>F2
D2-------->F1
D2-------->F2
if i selected A1 and B1 in a request from which FACT table will get the data and why can you please explain
please help me
reg,

Hi All,
I have a similar requirement where I have 4 multiple fact tables and we can't combine all those facts into one single fact table. In that case how can a query work with multiple common and uncommon dimensions and measures from multiple fact tables, if it doesn't work that way - can you please explain how can we expect a query to work with multiple fact tables.
For eg: D1– Dim
D2 – Dim
D3 – Dim
D4 – Dim
F1 –Fact
F2 – Fact
F3 – Fact
D1 -> F1
D2 -> F1,F2
D3 -> F2
D4 -> F1, F3
In this case if we want to query from D1,D2,D3, F1, F2 or D1,D2,D3,D4,F1,F2,F3. Kindly please explain how it can be modeled in BMM or what are the limitations. I have done with two fact tables in past and didn't had issues but this is kind of a vast implementation. Your help is appreciated.

Multiple Fact Tables or Circular Joins?

I'm using OE schema to build an rpd, I'm importing foreign keys and I'm unable to decide which tables to be joined additional to the imported foreign key joins. If I'm not making any new joins I'm getting multiple fact tables and if I do make some joins I'm getting circular joins, some one please throw some light on this.

It is not a good idea to bring the OE schema tables as it is. The ideal approach would be to create a view that would represent the Fact table. For e.g this view could comprise of OE headers and OE line information and the reference id to the other dimensions. 
 
Similarly create views from customer table, item tables etc and then create a star schema surrounding the fact view with all these dimension views.

Best approach to join multiple statistics tables into one

I have read different approaches to join multiple statistics tables into one, they all have a column "productobjectid".
I want to get all data for each product and put it to excel and output a jpg statistic with cfchart.
How would you do this, the sql part?
Thanks.

A couple suggestions:
1) when joining tables, its best to list both table/fields that you are joining in the FROM clause:
FROM shopproductbehaviour_views INNER JOIN shopproductbehaviour_sails ON shopproductbehaviour_views.productobjectid = shopproductbehaviour_sails.productobjectid
2) You add tables to a SQL join by placing another join statement after the SQL above:
SELECT *
FROM TableA INNER JOIN TableB on TableA.myField = TableB.myField
INNER JOIN TableC on TableA.anotherField = TableC.anotherField
3) If you have columns in the tables that are named the same, you can use column aliases to change the way they appear in your record set:
SELECT TableA.datetimecreated 'tablea_create_date', TableB.datetimecreated 'tableb_create_date'
4) Certainly not a requirement, but you might want to look into using <cfqueryparam> in your where clause:
WHERE shopproductbehaviour_sails.productobjectid = <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#all.productobjectid#">
You might want to consider checking out one of the many tutorials on SQL available online. Many of the questions you posed in your post are covered in pretty much every basic SQL tutorial. Alternately, a good SQL book is worth its weight in gold for a beginning web applications developer.

Something about two fact table in one subject

Hi all,
when I using two fact table in one subject, it can't make sense as expected.
The problem is describled as follows:
1.about the RPD:
In the presentation layer of Admin Tool, there is a mesure names "A", which is equal to B*C, come from table t1 and table t2 in logical layer respectively.
2. In biee Answeers, I created an answeer which includes some dimesions and the mesure A, another mesuare m1.
but in the the result pane, i saw there is no data in the the colume of mesure A, all other performs well.
3. so, I went for the NQquery for the phisical SQL, and found that,
in Where clause, table t2 is lost.
why? and how can I make it?

This sounds interesting. What would I join there? The dimension keys of the two fact tables?
Unfortunately this Logical Table Source stuff looks quite different in Admintool 11g. What would I need to create there?
Thanks,
Knut

How can build BMM with multiple fact tables

HI Gurus,
I have 4 fact tables and 18 Dimension table. Dimension tables have links with multiple fact tables. i have created physical joins in Physical layer. Now my questions is how can i create Business Model with multiple fact tables.
i mean should i create 4 fact tables as logical tables and logical keys ? Then i have to move all dimension tables in to Business model?
i am new to OBIEE. i gone through tutorial it is showing with one fact and multi dimension table. Should i do follow same style with multi fact tables.
Please help me. Thanks in advance for your support.

Thanks for your response.
I had drag all tables from the phisical layer to Business Model. then i have deleted all links and recreated complex joins with default values.
now i have some revenue amont columns in fact tables.
my question is should i should i create aggregation ( like Sum..) for those columns? is it must ?
please let me know thank you very much

BMM issue for multiple fact tables

Hi All,
I have three facts F1,F2, F2 and two confirmed dimension D1,D2 in my sample rpd.
In BBM layer , I tried to do the modeling as follows instead of creating one logical fact table. There are many fact tables to come
in future.
F1<----D1--->F2<----D2--->F3
When I deploy this sample rpd and run the report from F1 andF2, I get an error No fact Table exists at requested level of detail.
I have not created any hierarchical dimension to set up the content in the fact table.
I am very much thanksful for any advices.
Thanks,
Vishal

Hi,
Please refer the below link.
http://satyaobieesolutions.blogspot.in/2012/07/implementing-multiple-fact-tables-in.html
My suggestion would be bring both the facts to the same logical table sources and have a single fact table in the BMM layer joined with multiple dimensions.
Build a dimension hierarchy for the dimensions and then in the content logical layer mapping, map the dimensions to the fact tables with detailed level/Total
Refer the below link-

Hope this help's

Multiple fact tables in Essbase studio schema

Hi all,
Can we pull data from multiple fact tables in the single schema using essbase studio ? Also is it advisable ?
Please advice.
Thanks
Andy

Hi Glenn,
Thanks for the prompt reply.
Do you mean direct joins between fact tables ? or we can have indirect joins through Dimension tables ?
Thanks,
Andy

Merging Multiple fact tables and creating a BIA target

Hi Folks
We are using Dataservices with BIA.
We want to merge mutliple fact table and create a sinvglc cube on BIA.
when we tried to do that we get a error message that we cannot merge multiple fact tables.
any pointers ?
Poonam

You could have the cubes individually on the BIA and then have a multiprovider which you can use..?
or create separate universes on the cubes and then merge the universes in BO and then you could hit the BIA for the same..?
