FinncPriod is empty on document line

Hi Guys,

I'm running into a problem in Sap Business One.

Normally the field FinncPriod in a Sales Order or Purchase Order will be filled when you create a document.

This field will be available on document level and line level.

But when i add a new line to an existing order and update the order, the FinncPriod field on line level stays empty.

Does anyone has a clue why this field is empty in this case?

This does also happen in SBO 8.8.1.

Thanks!

regards William
