I have a requirement for which I need to add validation on payment method for Dunning through transaction F150. There’s no BADI/user-exit for this transaction.
I did some research and found there is a BTE 00001060 to handle this. I created a copy FM of sample functional module for this BTE. Added my own code and activated it.
Below are configs done to link custom FM to BTE:
After doing all these steps, my custom FM is not getting triggered for validation. Have I missed some steps on config side?
Your help will be appreciated.
