The contribution history for a giving unit is available on the History tab of the Giving Unit record. The Summary section lists all available contribution histories for that giving unit. Selecting a history from the Summary list will display the breakdown by giving fund for that giving unit in the Detail area. You can select multiple histories from the Summary to view a comparison of those histories in the Detail area.
CDM+ calculates the Current giving by summarizing all contributions made by the selected giving unit to the various giving funds since the end of the most recent history.
