I have two modules PROD and TRANS
TRANS module is having the dimension of TRANS and looks like this. Two line items PROD ID (List as Product) and boolean (checkbox).
Source  |  | Product ID  | Boolean Source  | 
|---|
TRAN001  |  | PROD001  | TRUE  | 
TRAN002  |  |  | FALSE  | 
TRAN003  |  | PROD 003  | TRUE  | 
PROD module looks like this
Dimension of Product and line items as Source Boolean )Boolean) and Product (List Product)
 | Source Boolean  | Source Product  | 
|---|
PROD001  |  |  | 
PROD002  |  |  | 
PROD003  |  |  | 
End Result should be
 | Source Boolean  | Source Product  | 
|---|
PROD001  | TRUE  | PROD001  | 
PROD002  | FALSE  |  | 
PROD003  | TRUE  | PROD003  | 
My problem statement is - there is no mapping module of having TRANSID AND PROD ID
I ran into the issues like "Automatic Sum" and "Dimension Mismatch"
Any pointes will be helpful. 
I tried simple lookup and summary method like LASTNONBLANK etc. which did not work
