Production RAF after delivery note


Have an issue here when trying to report a production as finished… I get the following message:

"A serial number group is not specified on the item and therefore cannot be automatically created.

Stock dimension Serial number must be specified."

There is a serial number group on the item. The serial number was added to “update registrations” when it was finished.

The production is created from a project and the manufactured items is already picked from the project, delivered to customer and invoiced.

We have had to wait to finish the production as we have waited for final cost from sub suppliers.

Are there any reasons why we can’t pick the manufactured item before RAF, or are there any settings I’m not aware of?
