Correct / cancel / reverse the excise invoice posted

Hi all,

Our End user post excise invoice in to the system . But as the excise invoice was posted without any reference document . Now he wants to reverse the excise invoice for some reason, but system is not allowing him to reverse it. Now in this case the some wrong accounts are posted in the system.

Can we post the excise invoice without any reference document ? Also as posting are already done we did JV using the J1IH, but some wrong accounts are posted , how to correct them?

Regards,

Vikram
