Unicity


The behaviour of uniqueness of some fields can differ from a customer to another. This property is managed via parameter settings for a selection of key fields (e.g.: email, group, asset tag) and not on the level of the data model:

  • The parameter settings will be enabled on forms and wizards.
  • When a field is defined as a unique key, a blocking error message will be displayed when a doubled entry is made for this field.

Example

  • Field Employee Name: this field is not defined as a unique key field, since several employees may have the same name.
  • Field Email: this field is defined as a unique key because every employee has a unique email address.

Notes

  • The setting for uniqueness parameters has nothing to do with the uniqueness defined in the level of integrations.
  • The list of eligible key fields is provided by Logo - EasyVista.png: You will not be able to add one.
  • The check for the respect of uniqueness is carried out when a form is saved or by the wizard.
  • The error message always is a blocking message, not allowing to save the form or the wizard: It will specify the concerned field (e.g.: Asset Tag), followed by the text Uniqueness Violation (which cannot be changed).
  • The same field label may appear on several forms or wizards, always check the application context of uniqueness of the field by the table to which it belongs.
