APEX Code for Owner of Opportunity - AN Urgent Reponse Needed

Dear All,
I've a typical situation on hand - There is frequent change of ownership of opportunities in our Org between Sales & Solutions team and it's imprative for us to track the last time Sales Team had changed the ownership of the opportunity to the Solutions Team.
Appreciate, if someone could please suggest a solution for this problem through a Trigger - A Skeletal apex code to achieve the same would be much appreciated.

Thanks & Regards,
Debendra

Hi Debendra, 

Have you tried setting the "field history tracking" for "Opportunity Owner" field? 

It tracks the both Old and New values for that field that changed overtime. 

If it Still doesn't satisfy you, Let me know I will try to provide code that suits your requirement.

Hi, I’ve enabled the field history tracking for the Opportunity Owner field – However, please could you provide me the SOQL query which will retrieve the Old and New Values of the Opportunity Owner and also suggest, how these values could be stored for future reference in the record.

Hi Deb,

You can use OpportunityHistory Object which maintain the record changes for every opportunity records. 

Please go through the Object structure:
https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_opportunityhistory.htm

Hope this helps!!!

Thanks,
Gaurav

You Can try this Soql Query
  
SELECT Opp.OldValue, Opp.NewValue, Opp.Field FROM OpportunityFieldHistory Opp

As for Storing these values in the record, I believe they are already stored in a Related list, Which you should Add it into your Page Layout ( look for "Opportunity Field History" and place it on the layout.

Let me know if it works

Best, 
Nithesh

If you only want Owner field, then filter it  
Select Opp.OldValue, Opp.NewValue, Opp.Field From OpportunityFieldHistory Opp Where Opp.Field = 'Owner'

Hi, Thanks for your help – Please could you explain, how to retrieve the ID for the OldValue & the NewValue for the Owner field of the concerned Opportunity. An early response will help.

Try this.... 
List<OpportunityFieldHistory> history = new List<OpportunityFieldHistory>();
for(OpportunityFieldHistory  t : [Select Opp.OpportunityId, Opp.OldValue, Opp.NewValue, Opp.Field From OpportunityFieldHistory Opp Where Opp.Field = 'Owner']){
    if(t.NewValue instanceof ID){
        history.add(t);
        System.debug('Old: '+ t.OldValue +' New: ' +t.NewValue);
    }    
    
}

Hi, Thanks again – However, when I tried to assign the OldValue to the OwnerId of the Opportunity using the below code , I’m getting an error -Illegal assignment from Object to Id : for(Opportunity oppr: opportunitiesToUpd ) { for(OpportunityFieldHistory opprFldHistory: history){ oppr.OwnerId = history.OldValue; } } Please could you help.

You are getting that Error, Because you are trying to assign a string to Id. First you need to convert it into ID. Try This... 
Map<Id,OpportunityFieldHistory> history = new Map<Id,OpportunityFieldHistory>();
for(OpportunityFieldHistory  t : [Select Opp.OpportunityId, Opp.OldValue, Opp.NewValue, Opp.Field From OpportunityFieldHistory Opp Where Opp.Field = 'Owner']){
    if(t.NewValue instanceof ID){
        history.put(t.OpportunityId , t);
        System.debug('Old: '+ t.OldValue +' New: ' +t.NewValue);
    }    
    
}

for(Opportunity oppr: opportunitiesToUpd ) { 
  if(history.containsKey(oppr.Id)){
      oppr.OwnerId = Id.valueOf(history.get(oppr.Id).OldValue);
    } 
}

This Should do the trick. Notice that I have changed the history(list) to map.

Hi Nithesh, Thanks very much – However, it seems valueof method is not supported for the ID primitive type as it’s throwing an error that variable Id not defined in the line : oppr.OwnerId = Id.valueOf(history.get(oppr.Id).OldValue); Please suggest.
