9.4. Validation Rule

This module provides management of validation rules. A validation rule is based on an expression which defines a relationship between a number of data elements. The expression has a left side, a right side and an operator which defines whether the former must be less than, equal to or greater than the latter. The expression forms a condition which should assert that certain logical criteria are met. For instance, a validation rule could assert that the total number of vaccines given to infants is less than or equal to the total number of infants.

To add a validation rule, just follow these steps from the Data Quality -> Validation Rule dialog:

Save each expression by clicking Save, then save the validation rule by clicking Save.

To edit a validation rule, click the name the relevant validation rule in the list and select "Edit" from the context menu. Then follow the same procedures as above when creating a new rule.

To delete a validation rule, click the name of the validation rule to be deleted, and select "Remove" from the context menu.

Validation rule names can be translated to other languages by selecting the name of the validation rule and selecting "Translate" from the context menu.

To view validation rule details, click the name of the validation rule, and then select "Show details" from the context menu.
