SAP Note 1241247 - BAPI does not update External Tax System

Component : Umsatzsteuer - Tax Interface (USA)

Solution : https://service.sap.com/sap/support/notes/1241247 (SAP Service marketplace login required)

Summary :
When posting an accounting document via BAPI_ACC_DOCUMENT_POST interfaced with AC_DOCUMENT_CREATE in SAP systems, users fully provide tax data. However, in setups with an external tax system, updates to this system can fail to occur, particularly relevant when using systems like VERTEX, TAXWARE, or SABRIX. This is specific to U.S. or Canadian company codes utilizing external taxation. To address this, SAP provides enhanced BAPI functionalities. Users are directed to implement enhancements including modifying existing function modules and setting up new ones, as detailed in the proposed step-by-step instructions. These corrections are meant to ensure external tax data synchronizes accurately with the SAP system. For correct application, adherence to the manual changes outlined is essential before triggering BAPI function calls, and verifying recent related notes such as those addressing tax calculation specifics is crucial.
