validation rule on two pick fields based on values

Question

I have two pick list fields product__c and Assigned_group__c

I am trying to write a validation if value on product__c picklist is DR user can only select L2 value on Assigned_group__c picklist and shows error if try to select other values on Action_Owner__c.

I have written this rule:

AND( ISPICKVAL(Case__r.Product_Type__c, "Digital Risk"), ISPICKVAL( Action_Owner__c, "L2" ))

but its not firing.

Answer 1

I added NOT condition and it worked.

AND( ISPICKVAL(Case__r.Product_Type__c, "Digital Risk"), NOT(ISPICKVAL( Action_Owner__c, "L2" )))
