Hi Hemant,

Please find the solution.

trigger opportunityData on Opportunity (after insert) {


list<opportunityLineItem> olilist= new list<OpportunityLineItem>();
    List<PriceBookEntry> priceBookList = [SELECT Id, Product2Id, Product2.Id, Product2.Name FROM PriceBookEntry WHERE PriceBook2.isStandard=true LIMIT 1];
    for(opportunity op:Trigger.New){
        OpportunityLineItem oli= New OpportunityLineItem();
        oli.OpportunityId = op.ID;
        oli.PricebookEntryId = priceBookList[0].Id;
		oli.UnitPrice = 7000;
        oli.Quantity = 5;
        olilist.add(oli);
    }
    if(olilist!=null&&olilist.size()>0)
        insert olilist;
      

}

Hi Abhinav,
I checked the link given by you.
But it doesn't answer my question that why we can't see this relationship in schema builder.

Hi Abhinav,

Please follow the link below you can definitely get your answer.

If you need to add new fields to Opportunity Line Items then Opportunity Product is the place. Basically Opportunity Product is same as Opportunity Line Item. It's just that in Salesforce the object name that is to be used in triggers etc for Opportunity Line Items is OpportunityLineItem and the UI name is Opportunity Products.

So to add new fields to line items for to Customize -> Opportunities -> Opportunity Products -> Fields.
And to add a new trigger to Opportunity Line Items you can also go to Customize -> Opportunities -> Opportunity Products -> Triggers, other then the two ways which I shared with you earlier.
