Summary :
After upgrading from SAP Release 4.6C to 4.70 and attempting to activate the LMR1M001 enhancement in SMOD, users may encounter the error XT465, indicating a parameter mismatch in tp configuration. The issue arises because the function module EXIT_SAPLMR1M_004 no longer exists in Release 4.70, replaced by the BADI 'MRM_WT_SPLIT_UPDATE' which now handles modifications for withholding tax and the split table. To resolve, users should delete the obsolete EXIT_SAPLMR1M_004 component from enhancement LMR1M001 via SMOD.
Key words :
error message xt465 'parameter &1, exit_saplmr1m_004 function module, 'exit_saplmr1m_004' user exit, transaction 'sap enhancement', 'mrm_wt_split_update' business add-, business add-, mrm_wt_split_update reason, transaction smod, lmr1m001 enhancement, tp configuration'
