In exporting INVTXN report, it is not showing the Product # when only selected fields are chosen.  We need, Date, Qty, AVGCOST. REF and the part number. MITI.KEY does not show up on the the list of field choices when setting up the report. I thought KEY this was the Product # and would automatically show on the report since it was not a choice  
 
what is the field name to choose for the product #.
