problem with excise calculation


my client has both purchase and sales excise duty of 2%.

But when he puchase an 100 item for 100 rs each the excise(BED) should be 200 but the vendor has given it as 190 so how to record this change


I think it’s a type of manual excise.

You have to do customization for that…or create a new setup where you have to give excise percentage as per Document.
