Posted on by Microsoft Employee

Hi,

Is there a way to set the voucher number that is used for ledger posting on a purchase order invoice manually?

Hope somebody can help.

Thanks,

Ludwig

    Hi Ludwig,

    This is not possible in standard AX. What would be your reason for this?

    Hello Andre, a customer has it's own archiving system that generates a unique voucher number. This number shall be identical to the  AX voucher number. That's why I asked whether there's a way to enter the AX PO invoice voucher number manually. Have to think how to realize that.

    thanks for the feedback.

    Hi Ludwig,

    You can try to use the invoice register and approval journal. Although it is no recommended, you can set the voucher series to manual. Then also test what will happen when the approval will be posted in a new period and the old was already stopped.

    Hi Andre, that's a no go for our customer because this journal generates a posting at the time the invoice is registered. They don't want to have that under any circumstance. Tried to use enter the externally generated voucher number in the document number field but our developers don't like that because the field is used in many other places in AX. I'm currently a bit stuck...

    Using the invoice register has also some other challenges when matching purchase orders. You could try to add a new field and change the logic to use this one as voucher. It would be a tricky customization.

    Hello Andre,

    May I have your opinion about the following idea ?

    1) Add the voucher field in the vendor invoice pool excl. posting details journal (the field is there by default it is just hidden)

    2) In the vendor invoice pool excl. posting details journal enter all invoice details + the voucher number generated by our customer's external system in the newely illustrated voucher field

    3a) For invoices without a PO:

    In the invoice journal, transfer the registered invoice via the standard transfer functionality.

    When doing this transfer, the voucher entered in the vendor invoice pool excl. posting details journal is not automatically transferred. Yet, I believe it should not be too difficult to make an adjustment that transfers this number into the voucher field and overwrites the voucher that comes with the invoice journal by default.  

    3b) For invoices with a PO:

    In the VendEditInvoice form create a lookup to the invoice entered in the invoice pool excl posting details journal. Once the invoice is posted the voucher number entered in step 2) is used for generating the ledger transaction and overwrites the number that is taken by default from the invoice voucher number series setup in the AP Parameters form.

    Would that in your opinion be a feasible "workaround" and a comparatively low risk adjustment or do you see any major risks in those adjustments?

    Would be great if you could give me a feedback on those steps.

    Many thanks in advance and best regards,

    Ludwig

    Hi Ludwg,

    I think this is a feasible approach. It looks like there are no other issues. Make sure that having this voucher manual is only for these scenarios and not others like general journal or e.g. sales orders.
