Hi,

I need help in below Trigger. I am unable to pull opportunity Id to insert Opportunity Line Items. I have hardcoded and inserted in below code.
Requirement:
I have a Custom Object where it has same fields as Opportunity Line Items. When Inserting Custom Object I want to insert Opportunity Line Items with respect to opportunity. Opportunity and custom object does not have relationship. But they have a common field called orderId where I can match Opp and Custom Obj.
 

trigger insertOppsLineitem on OrderItems__c (after insert) {
    System.debug('--- Inside OrderItems Trigger ---');      

    Set<Id> orderIds = new Set<Id>();
    Set<Id> oppIds = new Set<Id>();
    
    for(OrderItems__c oi : Trigger.New) {
        orderIds.add(oi.Id);
        System.debug('--- Getting Custom Obj Id: ---' + orderIds);
    }
    
    Map<Id, List<Opportunity>> oppMap = new Map<Id, List<Opportunity>>();
    
    if(!orderIds.isEmpty()){
        System.debug('--- Checking Order ID: ---');
        for(Opportunity opp : [SELECT Id, Name FROM Opportunity WHERE Name IN: orderIds]){
            orderIds.add(opp.Id);
            System.debug('--- opportunity Ids:' + orderIds);
        } 
    }    

    List<OrderItems__c> orderItems = [SELECT Id, Name, OrderId__c FROM OrderItems__c WHERE Id IN :Trigger.newMap.keyset()];
    
    List<PriceBookEntry> priceBookList = [SELECT Id, Product2Id, Product2.Id, Product2.Name FROM PriceBookEntry WHERE PriceBook2.isStandard = true LIMIT 1];

    List<OpportunityLineItem> oliList = new List<OpportunityLineItem>();
    
    for(OrderItems__c o : Trigger.New){
        System.debug('--- Order Items : ---');
       // for(Opportunity opp : oppMap.get(o.Name)){
            System.debug('--- Inside Opportunity');
            OpportunityLineItem oli = new OpportunityLineItem();
            oli.OpportunityId = '0060p000001rgcR';
            oli.PricebookEntryId = priceBookList[0].Id; 
            oli.Quantity = o.Qty_Ordered__c;
            oli.TotalPrice = o.Price__c;
            oliList.add(oli);
         //   System.debug('--- Inside Opportunity' + opp);
            System.debug('--- Oli List: ---');
        //}
    }
}

Kindly help to achieve this code freeze.

Thanks.
