If someone had cleared out the accounts specified in General Posting Setup and Inventory Setup (which is where the COGS and Inventory accounts come from, respectively), then the invoice wouldn't post and would give an error message that those settings are missing.
So something else is going on. Just momentary brainstorming - has the purchase invoice been posted that put the item into inventory (this is probably where cost would come from)? What is the Unit Cost field showing on the Posted Sales Invoice?
Did the order actually have any items on the lines?

It's turned off probably. Costs are registered but not posted to GL. You may post it by batch job Post inventory costs to GL.
