In OE Company Profile we can "Allow editing of invoice/credits".
We can then select which fields to allow editing.
We selected all the fields, including Salesperson.

But, when we select an Invoice form the current Invoices, the Salesperson on the Header tab remains blue (i.e. not editable).

Are we missing a step here, or does it not work?

Hello Sam,

It depends on where you are editing it from.

If you are editing the Salesperson from Current Orders/Invoices/Credit Notes, you can only change the Salesperson on the Invoices that have a Costed status of No.

If they have been Dayended, make the edit in History instead.

This is great. Yes, it works.
Thank you.
