SUGGESTED

When someone raises an order, they enter all the details and can amend the product description in a stock item or the detail in a free text item. 

This is visible when goods are booked in, yet when I go to post the invoice, the narrative is blank, logic says the narrative should be when the person has entered as description when raising an order. Why do we need to type this in again? 

It was sold to us with the impression that narrative would post on the invoice and my head is going to be on a block if the purchase department have to then re-enter the details. I really feel deflated about this.
