Missing purchase invoice no. (gap in number sequence)

(0) ShareShare
ReportReport
Posted on by TMNielsen 50

We have been using Business central for 5 month now and we didn't see this problem before.

Our No. Series for posted purchase invoices does not have the flag "Allow Gaps in Nos." but still we today saw a gap in the number sequence. 

Any idea how that happened? - and how we can prevent this?

Best regards

    Thanks for your reply Alfredo.

    We are not using purchase orders. We only post purchase invoices, so no partially received/invoiced order can exist.

    We only use purchase invoices and purchase credit memos and the lists with not posted invoices and credit memos are both empty.

    There must be an unposed invoice or order that has reserved No. 403140.

    Check your purchase invoice and purchase order list and apply a filter to "Posting No." and enter 403140.

    Usually, it's a partially received/ invoiced document that has reserved that number waiting to be posted in full.

    We have the same setup as we did in Navision. With this setup we use the same number range for invoices and posted invoices. In this way an invoice get the final number when we create it even if it isn't posted yet. If we delete an unposted invoice the system will automatic create an empty invoice to avoid a gap.

    We never had any issues with this setup in Navision and also so far no problems in Business Central.

    We posted invoices last friday and higest number was 403139. Today we posted invoices again and today the first number was 403141. So 403140 simply do not exist.

    We create purchase invoices via outlook integration and this is sometimes not realy working, but as far as we remember this was not a problem these last 2 fridays.

    Is  it a recent gap or a gap that occurred a while back in the number order?

    Sometimes a purchase order or purchase invoice can be assigned a posting number before it is actually posted and in the period between the assignment and the actual posting it can look like you have a gap.

    But if there is a gap in a number that should be posted long ago then we need to look for other explanations.
