You can hide duplicate data on a report with sorted records or on a report with grouped records.
How?
Note In any text boxes for which HideDuplicates is set to Yes, Microsoft Access prints a value in the first record in which that value occurs and, if records with the duplicate value continue onto another page, at the top of a new page.
How?
Note The group name will appear only at the beginning of a new group or at the top of a new page if the group continues for more than one page.
