The external validation function enables you to extend the core validation of SmartPlant Instrumentation. You can do this by writing your own logic code using C# or VB .NET and attaching it to SmartPlant Instrumentation Rule Manager using your Assembly Project signature.
The rule engine functions according to the Boolean value returned by the CustomValidation function. In case of 'False', the rule engine rejects the modifications made by SmartPlant Instrumentation users. In case of 'True', the rule engine accepts the user modifications.
