Hi,
When we capture and post the excise invoice in J1IEX or MIGO the account which are updated are the excise account as per setting in excise account table in SPRO CIN for transaction GRPO and the cenvat account is as per compnay code setting in CIN, but as in PO we are selecting excise tax code and for each tax condition of tax code GL account is assign in OB40 so when we do MIRO or GR for excise goods the account will get updated of Tax code account or from the CIN setting also when we do the utilization from which account system shows the available balance which we can utilize.
regards,
