Define the Uniqueness of a Type of Entity
  1. On your open source entity type maintenance screen, select the Overflow tab > Select the Uniqueness command from the list that displays.

    An example of the Uniqueness screen, for the Person Entity Type maintenance screen, is shown here.

    The Hard attributes area lists the hard attributes that are available for selection (you can't change hard-coded attributes).

    The Soft attributes area lists the attributes you have defined for the entity type, using the Entity Attributes screen (under Admin > Entity Definition > Attributes).

    The Uniqueness area lists the order in which the attributes are checked for potential duplicates.

  2. To include an attribute in the Uniqueness area:

    1. In the Hard attributes area, or the Soft attributes area, select the required attribute.

    2. Select the > button or double-click the attribute.

      The selected attribute displays in the Uniqueness area.

      You can't define a soft attribute as unique if it has the MULTIPLE option enabled, on the Entity Attributes screen.

  3. To exclude an attribute from the Uniqueness area:

    1. Select the attribute you want to exclude.

    2. Select the < button or double-click the attribute.

    3. The selected attribute displays in the Hard attributes area, or the Soft attributes area, as appropriate.

  4. To change the order of the attributes in the Uniqueness area:

    1. Select the attribute you want to move.

    2. Select the Move up button, to move the selected attribute up one position, or select the Move down button, to move the selected attribute down one position.

  5. To make all hard attributes mandatory, check the Make all hard attributes used for Uniqueness mandatory checkbox.

  6. Select Save.
