Guidelines to configure TAN Based Accumulation: 1) Maintain amount based accumulation in CIN details TAN exemption tab for both Invoice time and payment time tax type tax code.
2) Map the Invoice time tax type tax code with Payment time tax type tax code in View ‘V_FIWTIN_TDS_MAP’. ‘V_FIWTIN_TDS_MAP’.
Note: 1) Do not activate the standard accumulation functionality in your withholding tax type if you are using TAN based accumulation. 2) Multiple exemption certificates can be maintained for the same tax type but the Exemption from date should be different.
