Clarification on Allow OverApplication

Hello,

We had an issue where Autoinvoice Import program completed with error.

After a long 4 months of investigation we identified that select the "Allow OverApplication" box would fix this issue.

So we unchecked the Natural Application Only and checked the Allow OverApplication box for the Invoice Transaction type.

But now we noticed that Allow Overapplication never unapply the cash from the receipt automatically and refund.it.

How do we handle this case?

If we select the Natural Application Only, the autoinvoice program completes with error.

If we select  Allow OverApplication, automatic credit card refund will not happen.

Transaction batch Source setup : Automated Receipt Handling for Credits = Refund
