Custom Field based condition in PO tax procedure TAXINN

Dear All,

Actually I want Excise condition based on Plant/Cntrl Code/Vendor Excise Indicator. Vendor Excise indicator is not available for creating condition table so

I have added vendor excise indicator in KOMKAZ structure and wrote necessary code in EXIT_SAPLMEKO_001.

However still I am not able to get vendor excise indicator in PO (When see TAX procedure analysis)

Kindly suggest
