Where does the purchase order suggestions comments field pull from?

The database field is SugPOChg.Comment which says it is a freeform comments box. They are always empty for us but it would be useful if we could have something in there. The question is where is it supposed to pull these comments from and is there any way to edit the comments directly?

If this material is being purchased directly to a job it will come from the job material Purchasing comments field. So for example, if you wanted this material drop shipped, you would add that as a job material comment and it would appear for the PO Detail so the buyer knows to change the shipping address on the PO

Also, Requisition line comments will be seen here.
