Marlon:

If no one answers it usually means that no one has the answer to your question.

"Order not set to ready to invoice". is likely a "state of the order" rather than some flag that you can change.

By "state of the order" I mean things like not future dated and quantity on hand is available to fill the order if allow inventory below zero is not selected.

I'm assuming that your expectation is that following the import the auto invoice function is suppose to run. Try reading the manual, it might give you a clue.

I have implemented the auto invoice function and there is no flag that needs to be set 9that I've seen). All orders are manually entered and meet the normal manual requirements to invoice.
