I have a requirement to add new fields to a particular section in transaction BP for the Customer. I've added the fields fine and configured all the respective BDT steps. All that remains is the coding.
I have seen blogs on this but none of these elaborate on the coding aspect of adding custom fields. Within the PBO / PAI / SAVE / DATA Changed modules, which are all triggering fine, I don't know how to read the overall BP transaction data. So I don't know how to get the Partner number etc. so i can do subsequent checks and save the custom field values to the database etc.
I would appreciate if anyone could give me some ideas in this regard. I am just missing something but I'm having trouble determining what that is. I've tried various functions etc. but cannot get the data back into my custom function modules etc.
Your help and time are greatly appreciated.
