Detect duplicate entries

VTS lets you check that the entries in a column of the VTS table are unique. You can check whether an existing value is unique, or you can check that a value is unique when you enter a new value or modify an existing value.

Check that an existing value is unique

VTS lets you check if the value in a cell is unique in the column.

Right-click the cell that contains the value that you want to check, and then select Check Uniqueness. VTS indicates whether or not the value is unique.

Check if new or modified entries are unique

You can instruct VTS to highlight a new or modified entry if the entry is a duplicate of an existing entry in the column.

Note: You must specify this option for each column in which you want to check for duplicate entries. A small orange rectangle in the top right corner of a column title indicates that you have selected to display duplicate entries for that column.

  1. Select the column in which you want to highlight duplicate entries.

  2. Use the right-click menu or select Column Actions > Highlight Duplicated Entries. VTS places a check mark to the left of the Highlight Duplicated Entries menu option.

    VTS will highlight all new or modified entries in the column that are duplicates of an existing entry.


    • Existing duplicate entries are not highlighted.
    • Highlighting of duplicate entries is removed if you display another page and then return to the page with the duplicate entries.
