Purchase Order Number Sequence Error:

(0) ShareShare

Posted on by kmckelvey3 195

Hi guys,

One of our users is having the following issue in Production:

When creating a new PO under 91 - Procurement and Sourcing, it's pulling PO# 91-000194, which is an existing and Confirmed PO. When you finish the Header and hit Ok, it give the following error: "You are trying to create a purchase order with a purchase order number that already exists. Revise your number sequence setup for purchases and try again."

I've found the number sequence associated with POs for this company, and this shows it should be creating it as 196.

Next, I checked out the status list and it shows two free numbers:

Is there any other suggestions for trouble shooting this type of issue?

Thanks,

Kaleb

    looks like, the numbersequence generated a number that is already used.

    you have to remove it from the tree list.

    Could you please elaborate on the tree list? Not much experience on this piece of AX.

    From the screenshot I can see that it is a continuous number sequence. Continuous number sequence would not let go of any number missing so it maintains a list of numbers that could not be used due to any sort of interruptions. Sometimes it runs into issues, however if the auto cleanup is setup, it should reduce it.

    Could you please go to the PO number sequence, then click on the "status list" in the action pane above and you should find the #194 there. Please post a screenshot of that if you could. Given that 194 is already existing as a PO, you could delete that line from the list and try again to create a PO.
