We have a scenario where we are receiving data from Non-SAP system to SAP system through IDOC. Issue is while posting the data with ledger specific postings, there is an error "tax relevant postings are not permitted for individual ledgers Msg No. FAGL_POST_SERVICE020" even if there is no tax relevant information in the data receiving.. On the other side if we post manually the same data through FB01. it is a successful posting. We found a SAP note 114814 wherein it is given, the external data transfer (Non-SAP to SAP) doesn't comes under the purview of SAP Support. Has anyone came across the same issue? Thanks in advance. Early response would be really appreciated.
