Can R5 been linked with two receipts?

I have an issue in the following scenario.

I have an invoice with a gross amount of 100$. I am matching it with a receipt 1234 for which the payment amount is 80$ and 20$ is the deduction amount. Now after batch posting it ll create an entry in deduction manager. Again for the same company and customer if i create a standard deduction paid back for 20$ with new receipt 9876, will that close my previous deduction document in AR(will it remove the deduction open amount).

I have an issue where user created such transaction. User says that first receipt is the origin to create a deduction. And the 2nd receipt is the where it was paid back.
