Today’s TeamDesk update also introduces record validation rules.
Validation rules allow you to check the record’s values prior to submission to the database. If values match the condition criteria the message will be displayed to the user – either near the specified column, or on top of the form. You can find the link to validation rules under Rules section.
Validation rules would allow you to implement a range of restrictions varying from simple sanity checks such as one depicted above to a complex conditions – for example Finding Duplicates example can be easily extended with validation rules to prevent creation of the duplicates.
Please note that validation rules are low-level constraints and apply not only to editing operations but also to imports and operations via the API.
