How to read transfer rules of transaction UCWB

Hi experts!

Hope you can help me with this since I have like 3 days looking for the way to read transfer rules in "Mapping" section, in transaction UCWB; in order to develop it in an Abap program.

Is there any FM or has someone done this before ? Can anyone give me any idea on what should i do ?

I've tried to debug but it's a complete mess ... then i've tried to trace it ... and now i'm trying to map the transfer rules that seems to be spread in various tables ...

Please help me! I'm open to any suggestions!

Thanks in advance.

Dev.
