Tip! If the lumpsum variation is worth $5,000, it's generally considered best practice to set the quantity as 5,000, and the rate as $1.00.
The reason for this, is the Contractor doesn't always claim the approved amount. The Contractor may claim $6,127.58, instead of the approved $5,000, so this can easily be entered into the Progress Claim screen as the quantity multipled by $1.00.
