Gifts/Pledges - Pledge Period Controls
The "Update Pledge Control Information" screen is used to create a pledge period for a Gift Category (Fund) before managing the related pledges. You must create a control here first if you want to create a pledge for a Giving Unit.
Once a Pledge Control is saved, everything is unchangable. However, you can always (Erase) a pledge control with no pledges and create a new one.
