New Scenario -- how to map

Dear All,

We have Motorcyles for Corridor Petrol and all maintained in PM Module.

Now, they have a specific Petrol Pump for Petrol. After filling the tank, petrol pump authorities gives a credit memo to the Biker and keep a copy themselves for that petrol.

after 15 days, petrol pump authorities raise a bill and mention the number fo credit memo and other details.

after that FI make the payment.

Now to map in SAP.

Regards,

Pardeep Malik
