Opportunity Line Item Trigger

Hi Folks,

I am looking for the functionality where I can have the trigger which will auto populate the Opp Line Item if I select the specific line item.

For example If I add the "ABC" Line item to the Opportunity, trigger will auto populate the another line Item "XYZ" to the same Opp.

I have one rough draft of the trigger which is not working:

trigger AutoCreateProduct on Opportunity (after insert) { 
    List<OpportunityLineItem> OpportunityLineItems = new List<OpportunityLineItem>(); 
    for (Opportunity newOpportunity: Trigger.New) { 
        if(newOpportunityLineItem == 'ABC'){
            OpportunityLineItems.add(new OpportunityLineItem(OpportunityId = newOpportunity.Id,PricebookEntryId ='01un00000000000',Quantity = 1,UnitPrice = 0)); (This should be the another Line Item "XYZ")

Experts please help me.

HI James,

You can use the below Code Snippet and edit accordingly.
trigger CreateOLI on Opportunity (after insert) {
	List<OpportunityLineItem> oliList = new List<OpportunityLineItem>();

	List<PriceBookEntry> priceBookList = [SELECT Id, Product2Id, Product2.Id, Product2.Name FROM PriceBookEntry WHERE Product2Id='certain_id' AND PriceBook2.isStandard=true LIMIT 1];

	for (Opportunity oppty: Trigger.new) {
		if (/*certain_criteria*/) {
			//create new Oli
			OpportunityLineItem oli = new OpportunityLineItem(OpportunityId=oppty.Id, PricebookEntryId=priceBookList[0].Id /*rest of required fields*/);

	insert oliList;
Happy to help You!

Hi Lokesh,

Thank you for the Reply!

Could you please elaborate the code. Where I need to put the "ABC" product detail and where to put the "XYZ" product detail?
