There are several payment types available when a manual payment for an invoice is entered in AbaNinja.
For processing AbaNinja payment documents, an account proposal / cash account can be stored in Abacus for each payment type.
These are saved in the Abacus program F621 Application settings under Abacus Toolkit > AbaNinja > Account proposals > Cash account.
Here it is also possible to edit or delete an account proposal. No proposals can be added manually.
