Allowing the billing process to select charge reversals

Hi All

How can I select a charge reversal (coming from a recalc on my tuition) so it can be selected on my invoice? I have looked at the billing standard request and couldn’t find a setup that would make it be selected.

The original charge was selected on a previous invoice, and now I need to “bill” the reversal so it can be accounted on my gl process (my item type has a Billed timing on the GL interface setup).

I tried clearing the Select Invoice flag, but it causes the payments to be selected, and I don’t want that to happen.
