Hi Sudhir ,

Try with below code !
  
trigger roleCheck on User (before insert, before update){
    Set<String> roleNameSet=new Set<String>{'Finance Approver' , 'GHC Approver ' , 'Program Administrator'};
	Set<Id> userRoleIdSet=new Set<Id>();
	for(userRole useRol :[SELECT id  FROM UserRole  WHERE Name IN: roleNameSet]){
		userRoleIdSet.add(useRol.Id);
	}
	if(trigger.isInert){
		for(User usr : Trigger.new){
			if(userRoleIdSet.contains(usr.UserRoleId)){
				usr.adderror('Role Aleready Assigned, select new Role');
			}
		}
	}if(Trigger.isUpdate){
		for(User usr : Trigger.new){
			if(userRoleIdSet.contains(usr.UserRoleId) && usr.UserRoleId != Trigger.oldMap.get(usr.Id).UserRoleId ){
				usr.adderror('Role aleready assigned, select new Role');
			}
		}
	}
}
Let me know if it helps !!
Thanks

We can't use Validation rule for this.

Use trigger.

Hi Sudhirn,

Yes it is correct that this i snot possible in Validation rule .You need to write trigger ,You have to write trigger for before insert and updat eto check this validation .

You can try with below trigger it will help you to solve your problem .
  
trigger roleCheck on User (before insert, before update){
    Set<String> roleNameSet=new Set<String>{'Finance Approver' , 'GHC Approver ' , 'Program Administrator'};
	Set<Id> userRoleIdSet=new Set<Id>();
	for(userRole useRol :[SELECT id,UserRoleId from userRole  WHERE Name IN: roleNameSet]){
		userRoleIdSet.add(useRol.Id);
	}
	if(trigger.isInert){
		for(User usr : Trigger.new){
			if(userRoleIdSet.contains(usr.UserRoleId)){
				usr.adderror('Role Aleready Assigned, select new Role');
			}
		}
	}if(Trigger.isUpdate){
		for(User usr : Trigger.new){
			if(userRoleIdSet.contains(usr.UserRoleId) && usr.UserRoleId != Trigger.oldMap.get(usr.Id).UserRoleId ){
				usr.adderror('Role aleready assigned, select new Role');
			}
		}
	}
}

Hi Manjo, 


   I tried your method but UserRoleId  column do not exist in userrole object  I tried modifiing the code but no luck its not working 
  
trigger roleCheck on User (before insert, before update){
    Set<String> roleNameSet=new Set<String>{'Finance Approver','GHC Approver','Program Administrator'};
    Set<String> userRoleIdSet=new Set<String>();
    
    
    for(userRole useRol :[SELECT id,name from userRole  WHERE Name IN: roleNameSet]){
        userRoleIdSet.add(useRol.name);
    }
    if(trigger.isInsert){
        for(User usr : Trigger.new){
            if(userRoleIdSet.contains(usr.name)){
                usr.adderror('Role Aleready Assigned, select new Role');
            }
        }
    }if(Trigger.isUpdate){
        for(User usr : Trigger.new){
            if(userRoleIdSet.contains(usr.name) && usr.UserRoleId != Trigger.oldMap.get(usr.Id).name){
                usr.adderror('Role aleready assigned, select new Role');
            }

Hi Sudhir,

Please try with below trigger and test class !! 
trigger roleCheck on User (before insert, before update){
    Set<String> roleNameSet=new Set<String>{'Finance Approver' , 'GHC Approver ' , 'Program Administrator'};
	Set<Id> userRoleIdSet=new Set<Id>();
	Set<Id> userRoleIdSetToChk=new Set<Id>();
	for(userRole useRol :[SELECT id  FROM UserRole  WHERE Name IN: roleNameSet]){
		userRoleIdSet.add(useRol.Id);
	}
	if(!userRoleIdSet.isEmpty()){
		for(User us :[SELECT id,UserRoleId FROM User WHERE UserRoleId IN : userRoleIdSet]){
	       userRoleIdSetToChk.add(us.UserRoleId);
		}
		if(trigger.isInert){
			for(User usr : Trigger.new){
				if(userRoleIdSetToChk.contains(usr.UserRoleId)){
					usr.adderror('Role Aleready Assigned, select new Role');
				}
			}
		}if(Trigger.isUpdate){
			for(User usr : Trigger.new){
				if(userRoleIdSetToChk.contains(usr.UserRoleId) && usr.UserRoleId != Trigger.oldMap.get(usr.Id).UserRoleId ){
					usr.adderror('Role aleready assigned, select new Role');
				}
			}
		}
	}
}
@isTest
public class RoleCheckTest{
  public static testMethod void unitTest(){
     Profile prof=[SELECT id,Name FROM Profile WHERE Name='System Administrator'];
     UserRole ur = new UserRole();
        ur.Name='Finance';
        insert ur;
    UserRole urr = new UserRole();
        urr.Name='GHC Appro';
        insert urr;
	User usr=new User();
        usr.ProfileId=prof.Id;
        usr.Alias = 'standt';
        usr.Email='testduser@testorg.com';
        usr.EmailEncodingKey='UTF-8';
        usr.LastName='Testing';
        usr.LanguageLocaleKey='en_US';
        usr.LocaleSidKey='en_US';
        usr.TimeZoneSidKey='America/Los_Angeles';
        usr.UserName='adminusr@testorg.com'; 
        usr.UserRoleId=ur.Id;
        Insert usr;
        usr.UserRoleId=urr.Id; 
        update usr;
    }
}

Hi,
     My scenario is for certain Roles(say VP,Marketing) there should be only one user assigned. we can restrict user creation by triggers but how can i achieve this while assigning the user in Role hierarchy. If i assign more than one user in the Role Hierarchy and while saving, it should display an error message here also. 

Kindly give me some pointers on how to achieve this.
