Integration of SD and FI-CA charges
I need some help on SD charges integration with FI-CA. Based on other forums that I have seen I can configure posting areas 1200 and 1210. I have few specific questions based on requirements at my client.
1. I believe all the threads are based on the assumption that both SD and IS-U customer are available in the same SAP environment. My client plans to have these customers in different SAP boxes for ERP/SD and IS-U. I would like to know the feasibility and additional integration aspects involved if these customers rely in different boxes. Is it even possible to integrate their charges into one IS-U bill? Will this be similar to external billing system charges coming into FI-CA? What additional interfaces are required?
2. What configurations, enhancements are required to reflect payments back on the SD charges in both cases - customers in the same environment vs. different environment.
3. I saw that configuration allows to control accounting for such charges in SD vs. FICA. How does this config come into play if customers reside in different environment? Any charges that we post in FICA in one box will eventually be transferred to the ledger in ERP box by means of idocs.
Any information pertaining to these questions is helpful.
