This document outlines the excise utilization business process. It involves apportioning excise duty payables between available input credit registers (RG23A, RG23C, and PLA) and paying any remaining balance via a TR6 challan. If the available balances are insufficient, the payable amount is apportioned between the registers. An accounting document is generated and registers are updated based on the apportionment. A cheque and TR6 challan are then prepared in the financial system to pay the excise authorities, updating the PLA register and completing the process.
