This is a known scenario in Dynamics 365 Business Central (and older NAV versions). Is the PO is linked to a Prepayment Invoice?

Thanks

This is standard behavior, hopefully the information below can give you some hints.

Hello,

Are you using the same No. Series for both Purchase Order and Posted Purchase Invoice?

If yes, then this is standard system behaviour for audit reason. You can't have missing number for posted documents.

Hello,

Can you go to the affected environment and show the screenshot of your Purchase & Payables Setup > Number Series section

and

Go to your purchase order > page inspection and show the fields with "No. Series" filter.

Hi,

It is basically standard validation. This happens when you keep your no. Series for Purchase Order and Posted Purchase Invoice as same.

This message comes to stop you from creating any gaps in no. series in order to help you during audit.

So this is not an error and you better click on Yes and move on. This will do no harm in your database and will just create a blank Posted Purchase Invoice with 0 amount and a comment line.

Also if you want to change this behaviour then there are two options.

1 - Change the no. series for Posted Purchase Invoice to a different series.

2 - For this series go to No. Series page and select "Allow Gaps in No." field. This will allow this gaps to happen. Not advisable though.

✅ Tick the checkbox below to mark the answer as verified, if it helped resolve your question.

Regards,

Dhiren.
