Hi Ajeesh,
Have you checked the balance for the section key of the w.h.tax code in the J1INMIS report, does it nullify the balance? If you did posting with FBB1, the system wont nullify the balance in the report J1INMIS against the section key and it only nullified the GL balance. If you look the report for the document no/vendor against the section key, the system always show the balance. Due to this I suggested above solution. If you follow the above, the system will nullify the TDS in the J1INMIS and also its GL balance.
Regards,
Mukthar
