before insert any task how you can update it ?
try this one :


public class TaskToCommunity {

    public static void aftrupdate(Map<id,contact> oldmap,Map<id,Contact> newmap){

        list<Task> ta=new list<Task>();
        user u=[select id from user where alias='sree'];

        // profile p=[select id from profile where name='Partner Community User'];
        for(id key:oldmap.keyset()){
            Contact old=oldmap.get(key);
            Contact newmp=newmap.get(key);
            
            if(old.Phone!=newmp.Phone){
                Task t=new Task();
                t.OwnerId=u.id; 
               // t.OwnerId=p.id; 
                //t.OwnerId=userinfo.getUserId();
                t.Status='Pending';
                t.Priority='Normal';
                //t.WhatId=newmp.id;
                
                t.ActivityDate=system.today();
                t.Subject='Testing';
                ta.add(t);
            }
        }
        insert ta;
    }
}

My requirement is whenever contact phone is updated then assign to the partner user.

Hi Srikanth,
You are getting this error because a new list of task records is created and you are updating it. To use 'update' statement you should query the older task records, update any field in it, then use update statement.
  
public static void aftrupdate(Map<id,contact> oldmap,Map<id,Contact> newmap){

        list<Task> ta=new list<Task>();
        user u=[select id from user where alias='sree'];

        // profile p=[select id from profile where name='Partner Community User'];
        for(id key:oldmap.keyset()){
            Contact old=oldmap.get(key);
            Contact newmp=newmap.get(key);
            
            if(old.Phone!=newmp.Phone){
                Task t=[select Id,OwnerId,Status,Priority from task where OwnerId=:u.id limit 1];
               // t.OwnerId=u.id; 
               // t.OwnerId=p.id; 
                //t.OwnerId=userinfo.getUserId();
                t.Status='Pending';
                t.Priority='Normal';
                //t.WhatId=newmp.id;
                
                t.ActivityDate=system.today();
                t.Subject='Testing';
                ta.add(t);
            }
        }
        update ta;
    }

For now, I have used SOQL query inside the for loop (to avoid any other confusion), but it is not a recommended practice so you should create a map of tasks after querying all the required task records. I am not very clear with your requirement if you could elaborate 'My requirement is whenever contact phone is updated then assign to the partner user' then I may provide you with the exact solution.
Hope my answer helps.
If you have any confusion or need any clarification or have some other requirement please reply to this message.
