Control Lists maintain the content for grid drop-down lists in the People Register. If there are no entries in any specific Control List, then the related field on the People Register can have text entered.
If there are values entered, then the associated field can only select from the values in the Control List. The only member of the Control List selection not part of the People Register is Reg XL Tmplt. This field controls the list of Excel Register Templates available for download on the People Register Screen.
