G/L account not assigned to RG23AECS In customizing

Dear all,

while capturing excise invoice in J1IS trx, the system is showing the error message that g/l account not assigned to RG23AECS in customizing.

Our Fi consultant has maintained the G/L account in customizing in Specify G/L account per excise trx.

Kindly guide me how to overcome this issue.we are using Taxinn tax procedure.
