How to capture Retention in oracle AR

Hi,

Currently, customers are withholding 10%(or more) of the total amount as retention and paying the remaining balance. However, our system does not have a specific check or mechanism to identify this retained amount. As a result, we are currently reflecting it as part of the customer’s outstanding balance.

To ensure accurate accounting, we need to properly capture this retention amount through an accounting adjustment. Could you please advise on the best way to manage this or guide us on the necessary steps to implement this process?

How we can do. Kindly guide.
