This column is not available if the gift you are entering is a Pledge (Gift Class = PL). Gift amounts for Pledges are entered on the Pledge Entry window.
The total amount of the gift is required unless the gift is a pledge (Gift Class = PL). The total of all transactions in the lower pane of the window must equal this amount (soft-credit transactions not included).
If you are licensed to use CRM Constituent in JICS and a constituent has entered an amount in the Amount Today column for a pledge in Constituent, the amount will be placed in this column and treated as a "cash with pledge" type of pledge. This type of pledge generates PPs for the amount entered to pay some or all of the PTs generated for the pledge.
