Request for Validation Rule Implementation at Manage Format Level for Payment Purpose

I would like to discuss an enhancement we are considering for our current supplier payment processing mechanism. Specifically, we are maintaining a DFF at the supplier site level that utilizes attribute 9. Our goal is to implement a validation rule at the Manage Format Level that will improve our payment processing efficiency.

Here’s the proposed logic for the validation rule: -

1-If there is a value present in the DFF field at the supplier site level, the payment should proceed as normal.

2-Conversely, if there is no value in that DFF field, we would like to ensure that the corresponding supplier invoice is excluded from the Payment Process Request (PPR) and not processed for payment.
