Hello Dear,
Look Scenario:
You purchase a Excisable item, therefore your vendor gives you a Excisable invoice bill but you are not a Excise Registered Organization and you want to calculate or build that Excise Amount on Item right ???
Then you can create a non-Excisable tax code with same rate that was define in Invoice bill...
Make sure that time item should not be Excisable on ur Side...
You know how to Create a new Tax Code In SAP B1 ???
Only Change is that you want to write something else rather than CENVAT at the time of non-excisable tax code creation....
Regards,
Sandy
