I posting Document using Bapi's BAPI_ACC_DOCUMENT_POST and BAPI_ACC_DOCUMENT_CHECK .
When i was trying to post documents manually through FB70 on that time in BSEG table level BUZID field getting updated "T".
But i posting using this BAPI's means Bapi's BAPI_ACC_DOCUMENT_POST and BAPI_ACC_DOCUMENT_CHECK that BUZID field is not updating in the BSEG table level.
Help me out from this
