Do I need to have PI to use SAP FSCM Credit Management?
The simple answer here is no if you have Enhancement Package 5. However you need to implement WS-RM to replace the job PI does. If you have a PI server it does not make sense to look at the WS-RM option. If you do not have PI and want Credit Management it is worth considering WS-RM (if you have Enhancement Pack 5). To be fair this is more of technology question for your BASIS team to decide the landscape approach they plan to adopt.
