We have 2 scenario's where Inter-company charges needs to be billed & posted from DE(1010). This is mostly for random sundry costs recharges between company codes
1. 2 company codes active in the same server S4HC. e.g.: DE (1010) to post interco. charges to AU( 3010)
2. To a company code active in another on-prem system e.g. DE(1010) to US(1710) (On-prem)
The idea is to create a Debit Memo Request IC(DMR3) with a service material and further create a invoice (CI02). For 2nd scenario we can set up the automatic posting via idoc to the receiving company code.
The above process looks like it suits our requirement, but for inter-company do we need to consider to create a Sales Order/Purchase Order etc. as described in 3ZB, or we can go ahead to use the above listed process to post interco. charges?
