m not able to understand the difference of using globalconstant.null & isnull condition when Im creating PB criteria..
I had created PB that will update a custom field and fill that field with value from lookup field, and I set the criteria to check the lookupfield__r.customfield__c does not equal globalconstant.null before updating.. Using this criteria, gave me an error that said "the field has not been set or assign bla bla bla"..
But if I change the criteria to lookupfield__r.customfield__c ISNULL equal FALSE, it works like magic..
So what is the difference of those 2 criteria?
