Hi Katherine,
this is not a new restriction in NAV2013. For reversals, there have always been these rules:
- only for postings made by a Gen. Jnl.
- when customers/vendors are participants of the transaction, no application or adjustment must exist
- when VAT has been posted, the VAT entries must not be closed.
Most of these rules are for simplicity / repeatability. As a NAV developer, you can easily remove the "VAT must not be closed" and the "No Adjustments" rule. You need to know the consequences of this, though. In both cases, the previous adjustment/closing postings are off by the reversed amount. These need to be taken care of in the next VAT reporting and closing / adjustment of exchange rates. To do this is accounting best practice, IMO, so no real problem here.
with best regards
Jens
