Summary :
When using BAPIs such as BAPI_ACC_DOCUMENT_POST and providing tax data in specific interface tables like ACCOUNTTAX, users should be aware that in the AC_DOCUMENT_CREATE function, such tables (e.g., T_ACCTX) may not contain the data. Instead, tax data are included within the T_ACCIT table marked with TAXIT = 'X'. This is notably pertinent under the document compression scenario guided by SAP notes 36353 and 643273, where tax details get summarized alongside financial documents, and only this summarized output feeds into external tax systems.
