AP Parameter Check the invoice number used - does it have a validation on the transaction type?

(5) ShareShare

Posted on by Sha02 205
Hi, good day!
Does account payable parameter Check the invoice number used, have validation on transaction type?
Check invoice number was set to Reject duplicate.
 
Below is the scenario I tested and it rejects the invoice journal:
PAYMENT JOURNAL: Invoice number TEST1 was used in the payment journal/advanced payment
INVOICE JOURNAL: invoice TEST1 will be recorded in the invoice journal (not posted due to reject duplicate checking)
 
Is this correct? or there should have a validation for payments and invoices?
If there is a separate set-up for validation, where can I find it in D365?
 
Thank you.

    Hi Sha02,

    When you post a payment, you should not provide the invoice number on the journal line. It will think you are posting a credit note. Instead, mark settlements to link the payment with open invoices.
     
    The Accounts Payable setting is the only setting for managing if you allow or reject duplicate invoice numbers.

    Hi Sha02,
     
    The account parameter setup does not validate the transaction type.
     
    As Andre suggested, it is not mandatory to enter the invoice number for a payment transaction. You should post the invoice transaction first, and while posting the payment, you can use the settlement option, which will link the payment to the invoice. If you post a prepayment first, you can use the settlement option while posting the invoice to link the prepayment to the invoice.
     
    Therefore, the invoice number should ideally be entered only during invoice posting.
     
    Regards,
    Bharath Jain.
