Merge two rows in one row with extra column

Hello,

We are on BI 4.1 on Windows. I am an administrator and want to write a basic WebI report. How can I merge the master and details rows into one row. The customer no, Name, item comes from TAB1 and code and value comes from TAB2.

Customer no     Name     Item     code     value

12345               Name1     IT1     17          23.00

12345               Name1     IT1     63          45.00

Teh TAB2 will always have multiple rows for one item based on the code field. I am only interested in two always. The code 17 means price and 63 means maintanance cost for 5 years.

I want it to display in one rows like -

Customer no     Name     Item     Price     MaintCost

12345               Name1     IT1     23          45.00

The value of Price and MaintCost will defined based on the code field, which is in TAB2.

How it is possible in Web Intelligence 4.1? I am hoping it is something simple to model for a technical administrator.

Please let me know.

Best Regards,

SS
