Hi @JAI_PRAKASH_SINGH ,

DMN does not accept regular expressions per se, but this post might help show you how to accomplish the same thing with FEEL: Zeebe DMN Worker : literal expression in Javascript not supported - Zeebe Client - forum.camunda.io

For reference, FEEL has the built-in function matches() to check regular expressions.

Your expression should work and returns true if the input value matches the pattern.

matches(?, "^[a-zA-Z0-9+_.-]+@[a-zA-Z0-9.-]+$")
