AP Invoice Header with No LInes - Picked up by Sweep, Causes out of balance?

Does Oracle Payables consider an entered invoice header in "Never Validated" Status and thus not accounted when balancing out AP to GL?

In our instance, it seems to almost not exist from balancing perspective:

1. Does not get picked up in exceptions report

2. Does not get picked up in Unaccounted report

3. Does not get picked up in Sweep

4. Does not cause an out of balance

I believe I've concluded that it is almost non-existent from an AP balance / close / amounts perspective but we are very behind on patching so I am doubling checking with you guys.

Thanks!
