Revenue Segregation between two revenue accounts

[mmrahman]

Dear Friends

I am facing a serious problem to segregate revenue amount in two different account codes when sales invoice would transfer order management to receivable module. Suppose sales amount is 100, client wants to see the below journal in receivable module.

Receivable A/C (Dr) 100
Revenue A/C (Cr) 80
Reserve A/C (Cr) 20

My question is, how can I do the solution to my client?
