I need to require that users with our "Sales User" profile fill out a specific set of fields when the move an opportunity in to our "Closed Won" stage. Other users/profiles will not have this requirement. I have other similar versions of this rule for a single field for all users and it works, but for this exercise, I need to account for 9 required fields and only with a specific profile. My formula is not returning errors, but when I tested this with a Sales User, SF did not require them to fill out the fields. I did change their profile moments before asking them to test. Do Profiles take a few minutes to reflect a change. (Yes - I did have them sign out, changed the profile, then had them sign back in.)My current validation rule formula is:AND(CASE( StageName ,"Closed Won", 1 ,0 ) = 1 ,ISBLANK( Vendor_Rep__c ),ISBLANK( Vendor_Rep_Help__c ),ISBLANK( Business_Challenges__c ),ISBLANK( Business_Win_Process__c ),ISBLANK( Key_Takeaway__c ),ISBLANK( Solution_Search__c ),ISBLANK( Competition__c ),ISBLANK( Overcoming_Competition__c ),ISBLANK( Implementation_Details__c ),$Profile.Name = "Sales User")Thanks for the help!
