Create a new Detail Page Button on the Opportunity object. Set Behavior to Execute JavaScript and Content Source to OnClick JavaScript Paste the Below snippet of code in the window {!REQUIRESCRIPT("/soap/ajax/39.0/connection.js")}  {!REQUIRESCRIPT("/soap/ajax/39.0/apex.js")}  var retStr;  retStr = sforce.apex.execute(" CloneOpportunitywithRelatedObject "," cloneOpportunity ",  {oppId:"{!Opportunity.Id}"});  location.replace('/' + retStr);   Create a new Apex class and paste the below snippet of code global class  CloneOpportunitywithRelatedObject  {     webservice static Id  cloneOpportunity (Id oppId) //  pass parameters     {         List < Related_Object__C > relatedList = new List < Related_Object__C > ();   // query all the fields you need to clone          Opportunity opp = [SELECT ID, CloseDate, StageName, Type, Name FROM Opportunity                                        WHERE Id =: oppId

Create a new custom field on opportunity called  Update_Due_Date_of_Task__c (Date/Time) and create the below trigger on task object.  Output : If there are multiple tasks on opportunity the above custom field will be updated by due date which is greater from all task's due date. Trigger updateLastActvtyUpdateOnOpty on Task(after update, after insert) {     Datetime lastUpdatedDate;     Set < String > whatIDs = new Set < String > ();     for (Task tskObj: Trigger.new) {         if (tskObj.whatId != null && tskObj.ActivityDate != null) {             whatIDs.add(tskObj.whatId);         }     }     If(whatIDs.size() > 0) {         Task taskObj = [select Id, ActivityDate, WhatId from Task where WhatId =: whatIDs                                  order by ActivityDate DESC LIMIT 1];          lastUpdatedDate = taskObj.ActivityDate;          // update Opportunity 's custom field Update_Due_Date_of_Task__c         opportunity[] optyObj = [select Id,Update_
