Provisional and FInal Bill Account Determination

Dear Experts,

We are implementing SAP SD Module for a Thermal Power plant.

However for Energy Billing they have a unique requirement

Provisional Billing (1st to 25th of the month)

Final Billing (26th to 30th of the month)

The want the following Accounting entries to be generated by the system.

When raising Provisional Bill

1. Customer A/c Dr

To Progress Billing Account Cr (Liability Account)

When raising Final Bill

2. Customer A/c Dr

Progress Billing Account Dr (Liability Account)

To Revenue A/c Cr

Both these needs to be generated from a single sales order. The Progress Billing Account balance will be Zero.

Please Advice

Regards

Gautham.
