FM to get Complete BP Details

Hi Experts,

I have a Requirement where I am working on Transaction BP in CRM Systems.

The Requirement is as follows:-

" When I Create/Modify a BP by Person/Organisation/Group, All the Details that I enter, On press of SAVE..they should be saved in the Database Table: While the Data is getting SAVED, I need to fetch that Data which is getting stored and I need to pass that data to a Non-SAP System"

I need a Function Module for the same that captures all the Details that are related to the BP Transaction...?

Regards,

Kanika
