We need to populate PO, PO Item and Batch on PEXR2002 IDoc's segment E1EDP02. Based on some search, I found that User Exit zxf08u04 in EXIT_SAPLIEDP_002 can be used to get this functionality.
When I put a Break-Point in Include LIEDPF15, when it calls the User Exit, and ran Tcode F110 or Program RFFOEDI1, it's not stopping at this break-point. I want to see how the data is being gathered.
Also, Include LIEDPF15 is used in Main Program SAPLIEDP (EDI - Payment/Payment Advice Processing).
I want to understand how Programs RFFOEDI1 and SAPLIEDP are connected.
Could you please help me? I greatly appreciate that.
