We are using MM-SUS scenario (with SRM 7). In invoice replicated from SUS I am getting the default tax code from SUS system and not from ECC (PO). I am looking for option when invoice gets transferred from SUS to MM it should use tax code from ECC.
In MM: I have done customizing for EDI tax code i.e. OBCA/OBCD/OMRY is completed
In SUS: customizing SRM server -> cross application basic settings -> tax calculation is completed.
1. Determine system for tax calculation --> R/3 tax calculation occurs in backend
2. Enter tax code --> I0 = 0 % default input tax and I1 = 8 % AP sales tax
3. Assign enterprise buyer tax code to FI system --> We have defined same tax codes in SUS and MM
Please suggest solution for this issue i.e. while replicating ECC invoice from SUS, how system can pick tax code and tax amount from ECC only.
