The invoice is in open status hence, the disabled fields cannot be edited.

I used to be able to set the invoice to "active" add the retainer fee then still update items with in the active invoice. This morning I go to add qty's to a clients order and I can't make any changes, well except to the PO.

Is this new? How do I disable this feature?
