Hi,

You can write a trigger and then using below code you can update the saem..
  
Populatetrigger on Custom_Object__C (After insert, After update)
{
	list<user> lstUsersToUpdate = new list<user>();
	
   for(Custom_Object__C obj : trigger.new)
   {
			user objuser = new user(Id = obj.userlookupField)	;
			objuser.Qulification_field__c = obj.Qulification_field__c;
			lstUsersToUpdate.add(obj);
   }

	if(!lstUsersToUpdate.isEmpty())
		update lstUsersToUpdate;

Please check and let me knbow if ir helps you

Hi,

What is the relation between custom object and user object ?

Hi sandeep,

           Thanks for reply

  I have took the lookup relationship  from custom object  to user
sandeep sankhlasandeep sankhla
okay so you have lookup on custom object for users...means custom object is a chil and whenever you are inserting and updating the custom object same field you want to populate on user object is this your need ?

 trigger Populatetrigger on Department__c(before insert, before update)
{
    list<user> lstUsersToUpdate = new list<user>();
    
   for(Department__c obj : trigger.new)
   {
            user objuser = new user(Id = obj.User__c)   ;
            objuser.Qualification__c= obj.Qualification__c;
            lstUsersToUpdate.add(obj);
   }

    if(!lstUsersToUpdate.isEmpty())
        update lstUsersToUpdate;
        }

I am getting this type of error
 Incompatible element type Department__c for collection of User

Hi


lstUsersToUpdate.add(obj);

in this you should add user object not department__C


lstUsersToUpdate.add(objuser); use this as its a user type list..

Thanks
