The below validation rule works fine but I'm curious to know how can I show the required error message next to the field? As you can see below I have multiple fields and I have selected to show the error on top of the page since I have two fields to validate for
ISBLANK is that possible in Validation Rule? or do I have to use VF Page to do that?
AND(ISPICKVAL(Status__c, "Completed") , OR( ISBLANK(Completion_Date__c), ISBLANK(Last_Completion_Date__c) //you can multiple fields just by adding here.... ))
