Hello!
I'm trying to validate an attribute "Reference Number" with another attribute/ field "Sub Area" with substring of sub-area in D2's properties page while importing a document.
For example: if the sub-area is "5-Internal" then the Reference number should start with "5". If there's any other number, then it should be validated and given a error flag.
I tried applying uniqueness check but it doesn't work on the same object so I was wondering if there's any other way to validate one attribute based on the value of another in the same properties page ?
Let me know if there are any ideas.
