Trying to check user permission set from related object validation rule

Question

Submitter field in the object has lookup to the user object. I am trying to create validation rule where only user with a specific custom permission set can be assigned to submitter field. But cannot figure out how can I check permission set of the user. Any ideas please

Answer 1

You are mixing up two similar terms. First is Permission Set, which you cannot check for in validation rules, and requires queries from Apex. The second term is Custom Permission, which is easy to check from Validation Rule, and simply needs to be added to a Permission Set somewhere (it can be at the Profile level).
