Hi Rashmi,
You can find it in following way:
(1)Goto transction FIBF menu Environment->Info System (P/S )
(2)Select the BTE you want to implement.
(3)Press button Sample function module
(4)This brings you to SE37 – Copy the sample function module to a Z-function module (First create a new function group for the function module). Note: The name of the Z-functionmodule is not important
(5)Edit the code in the new function module
(6)Go back to transaction FIBF – Menu Settings->Products -> Of a customer and create a new product which identifies the new product . Remember to mark the Active field.
(7)Go back to FIBF menu Settings->P/S function modules->of a customer – Create an entry that links the BTE and Product with the new function module
Hope this will help you..
Thanks & Regards,
Shefali
