There is a Field setting on UI Designer where we can set the property "Mandatory" of the field as "True", but this setting is only used for aesthetic purpose. It will only add the read '*' on top of the field label, but no Runtime validation on client will be added.


To set a Custom Field of a Custom UI View as mandatory you can use one of the following ways:

1. Use a ABSL Script Event (Event-BeforeSave and Validation-OnSave) to check if any valid value was maintained on the field, raise error message and prevent save in case the value is empty or not valid.


2. Use the Key User Tools (KUT) to change the properties of this field and set it as mandatory.
