Urgent: Add field in generic data source

Hi,

Could anyone please help me out in resolving the issue to add field from different table in generic datasource.

How can I add it in R/3 data source when a function module was created in ABAP to generate fields from PLPO table?

Whatz the changes has to be done at BW side to map the added field?

<u>Requirement</u>

_________________

1) Need one more field in the extractor. Field name is PLAS-LOEKZ. Initially client wanted me to add PLPO-LOEKZ which I added, now he needs the same fields from both the table (PLAS and PLPO).

2)The name of the extractor/structure is ZBW_ROUTINGS_OPERATION

3)Now, we need to add this field (LOEKZ from PLAS) in the function module as well. FM name is: Z_BW_ROUTE_OPERATION_EXTRACTOR. This will be in a SELECT query. We need to add this field in the SELECT statement.

Testing will be done in following steps

1) Go to Transaction RSA3.

2) Enter the data source “Z_BW_OPERATION_ATTR”(not sure about the name though, but it should end with OPERATION_ATTR)

3) Enter the following details:

EXTTY – I

PLNNR – 50000032

PLNTY – N

4) Now execute (F8) the transaction.

5) Click on “Display List”

6) In the output, we should be able to see these 2 columns(PLAS-LOEKZ) and (PLPO-LOEKZ)

Please send your valuable suggestions to resolve the issue ASAP as its damn urgent.
