Excise Entry Rg23aII or C II -Debit through general journal

Hi,

I wud like to know the procedure for making payment / debit in RG books i.e. A II or CII. I knwo the functionality of function -payment-suggest lines. however wud like to debit other than this method since there is no liability through sales invoice e.g. I want to debit assessment dues in RG23 A books or Excise duty on Export rebate claim.

What is the method through whcih i can debit to rg books?
