Calculate Due Date from Invoice received date in FICA.

Hi,

Our business scenario is that, we are generating invoice from ISU and sending to the customer via courier. Now, Once customer receives the invoice it sends us the acknowledgement that Invoice has been received on so and so date. Now, we are suppose to calculate the due date from Invoice received date. The 2% discount should be given to customer if payment is received within 5 days of invoice received date else it should be given 1% if payment is received within 30 days of invoice received date.

So, it is pretty clear that Baseline date cannot be fixed in Payment terms in OBB8.

How this scenario can be handled in FI-CA?

Thanks

Viraj.
