assigning Opportunity ID to Opportunitlineitem records

I am creating a Opportunity & Opportunity Products via a Apex Code. I am able to create a Opportunity. For the created Opportunity, I want to add some Opportunity Product (OpportunityLineItem) recirds. My Code is

ID OppID;
OppID = opps[0].ID;  //Get the ID for the added Opportunity

//Now I want to add Products
OLI = new OpportunityLineItem();
 OLI.Opportunity.ID = oppID; // Getting runtime error = Attempt to de-reference a NULL Object
 OLI.product2.ID = cdtl.product__r.ID; // This works

Pl. help

Hey Anil,

It's worth going through the relationship between Product, Pricebook, PricebookEntry, Opportunity Product. All you need to create Opportunity Product is OpportunityId, PriceBookEntryId of the product, Unit Price & Quantity.

Please go through the this https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_opportunitylineitem.htm to know about the required fields.

Thanks,
Natarajan

Opportunity Opp = new Opportunity(); // New Opportunity

//Now I want to add Products
OpportunityLineItem OLI = New OpportunityLineItem(); //New line item
OLI.OpportunityId = Opp.id; // Adding OLI to Opp

still same issue -
OLI = new OpportunityLineItem();
OLI.OpportunityID = OppID;

Check last line..
OLI.OpportunityId = Opp.id; // Adding OLI to Opp

If you look at my first 2 lines in the origina post, I am getting the opp.ID into a var called OPPID & assigning the OPPID.

Works fine for me,

List <Opportunity> Opps = New List <Opportunity>();
Opps = [SELECT id from Opportunity Limit 1];

ID OppID = opps[0].id;  //Get the ID for the added Opportunity

//Now I want to add Products
OpportunityLineItem OLI = new OpportunityLineItem();
OLI.OpportunityID = oppID; // works fine

Try this code
  
ID OppID= opps[0].ID;  //Get the ID for the added Opportunity

//Now I want to add Products
OLI = new OpportunityLineItem();
 OLI.OpportunityID = oppID; // Getting runtime error = Attempt to de-reference a NULL Object
 OLI.product2.ID = cdtl.product__r.ID; // This works

 
Anil Rao 17Anil Rao 17
Works now with the below 2 lines -     OLI.Opportunityid = oppid; &      OLI.product2ID = cdtl.product__r.ID;

However the Products are still not being added into the Opportunity Product Object. I am not getting any errors. PL. HELP.....THIS IS THE LAST PIECE in my POC....

Greatly appreciate.....

Got it. All I was missing was assigning a PriceBook at the Opportunity level. I had a single pricebook assigned for a Product. So was assuming that when I add a product the default prcebook will be taken. Also what confused me was that when I add from the entry screen, I am not asked for a Pricebook. I can just add a Product. Hence was trying to duplicae the scenario via apex.

Adding a Pricebook to a Opportuity solved the problem.
