Function module in BW for Balance Sheet

Question

Dear all,
i have a request to create a FM for BW module.I'm new at abap in BW so i want kindly to ask you to help me with some material or knowledge that you have.
The specific request is for Balance Sheet. It is done in BW with routine but i have to add this routines in one functional modul.The misunderstanding for me is that this routine use some standard form (like compute_data_field which is call dynamically ) for input parameter and i'm not sure in my FM how to take the same input parameter.
If someone have some expirience with this i will rewards with points
Thank you.

In the BeX, when you are creating the query, you need to create a variable to the object by doing the following:
1 Select the object in the leftside
2 create new variable
3 in the variable select the eleboration with customer exit
4 after creating the variable, go into transaction CMOD
5 Select the project for BW, if you don't have one, just create it. (You need to include it into the data packet for BW, if you don't have you must create it otherwise you'll get the data packet tmp and you cannot transport it)and select the Henancement Assignment RSAP0001.
3 In the components area you'll get 4 functional exit:
EXIT_SAPLRSAP_001
EXIT_SAPLRSAP_002
EXIT_SAPLRSAP_003
EXIT_SAPLRSAP_004
click on the first exit and than click on INCLUDE ZXRSAU01
in this include you go in the change mode and input this kind of code:
WHEN 'name of the variable'.
PERFORM and input your code.
