Hello,
I have a question regarding field validation. What is the best/easiest way to create a validation for the customer field in the agreement.
The customer entity has a new field "blocked" and choosing a blocked customer in the agreement should throw an exception.
I tried a jscript function but I am not sure how to fetch related customer record, or if it is possible? Or is the best way using an c# plugin?
Or is there an easier way?
Thanks
Dominik
