Merge dimension Does not work from two data sources

Hi

We are using Merge dimension for a report.

Summary :

We have Network Product code and Text;TSA Product code and text; as dimension objects

Net sales :Measure .

Cognos Product is available on one data provider.

So In order to get Net sales from Cognos perspective we are using merge dimension based on Net work product and TSA product.

We do have Network product and TSA Product from both the data providers and so merge is based on both.

But when we just take the Cognos and revenue in the table it gives just one value and not consolidated

for eg

Cognos product               Net sales 

BB other Products                123

BB Y Product                         123

BB Z product                          123

But if

Cognos Product           TSA Product      Network product      Net sales

BB other product                abc1               xyz1                              23

BB other  product               abc1               pqr1                              56

BB other product                                                                            123 (This value again gives the one sum vales ) The format is break here applied

BB Y product                     def1               lmn1                                  67

etc

So this is the problem I used force merge for each In  but nothing is succedded.

Force merge works well with excel but not with different data providers.

I have one Both the universes and database is Teradata and SQL server

Thanks and Regards

Gaurav.
