Issue regarding cancellation of Excise Invoice

Hi all SAP experts,

I have an issue related with excise invoice cancellation. When I create an invoice in VF01 at the time of saving the invoice the system automatically creates the excise invoice in the background. I get the excise number using transaction code J1IP. Here I enter the commmercial invoice number & after pressing "F8" the system displays the excise invoice number.

When I am trying to cancel the excise invoice using J1IIN transaction code the system is giving the following error:

"Modvat Accounts not defined" When I click on this error to view the details the system displays G/L accoutnnot defined for CEIV & excise group "10".

Please help me on this issue as I am not able to find the solution.

With best regards,

Tulsi Jiddimani
