Hi,
I have created a schedule class to RUN every 1 hour but It is not checking the newly created record and inserting. Kindly review my code and let me know what changes need to be done.

My Requirement:
I want to write a schedule class on custom object to check newly created custom object record is created in Opportunity Line Items.
I have a field common to find custom obj and opportunity which is used to find opplineitems.
 

global class orderItems Implements Schedulable {

    global void execute(SchedulableContext sc) {
        insertOrder();
    }

    public void insertOrder() {
        
        List<OrderItems__c> lstOpty = [SELECT Id, Name, OrderId__c, Due_Date__c, Name__c, Discount_Amount__c, Price__c, Product_Id__c, Product_Type__c,
                                              Qty_Backordered__c, Qty_Canceled__c, Qty_Invoiced__c, Qty_Ordered__c, Qty_Refunded__c, Qty_Returned__c, Qty_Shipped__c, Sku__c
                                          FROM OrderItems__c WHERE CreatedDate > TODAY];
        
        Set<Decimal> orderIds = new Set<Decimal>();

        for(OrderItems__c oi : lstOpty) {
            orderIds.add(oi.OrderId__c);
            System.debug('--- Getting Custom Obj Id: ---' + orderIds);
        }
        
        Map<Decimal, List<Opportunity>> oppMap = new Map<Decimal, List<Opportunity>>();
        
        if(!orderIds.isEmpty()){
            System.debug('--- Checking Order ID: ---');
            for(Opportunity opp : [SELECT Id, Name, OrderItem__c FROM Opportunity WHERE OrderItem__c IN: orderIds]) {
                if(!oppMap.containsKey(opp.OrderItem__c)) {
                    oppMap.put(opp.OrderItem__c, new List<Opportunity> {opp});
                    System.debug('--- Opportunity Map ---' + oppMap);
                }            
            } 
        }
  
        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 oi : lstOpty){
            System.debug('--- Order Items: ---' + oi);
            if(oppMap.containsKey(oi.OrderId__c)){
                for(Opportunity opp : oppMap.get(oi.OrderId__c)) {
                    System.debug('--- Inside Opportunity ---');
                    OpportunityLineItem oli = new OpportunityLineItem();                
                    oli.OpportunityId = opp.Id;
                    oli.PricebookEntryId = priceBookList[0].Id; 
                    oli.Quantity = oi.Qty_Ordered__c;
                    oli.TotalPrice = oi.Price__c;                
                    oli.item_id__c = oi.Name;
                    oli.Name__c = oi.Name__c;
                    oli.product_id__c = oi.product_id__c;
                    oli.Due_Date__c = oi.Due_Date__c;
                    oli.product_type__c = oi.product_type__c;
                    oli.qty_backordered__c = oi.qty_backordered__c;
                    oli.qty_canceled__c = oi.qty_canceled__c;
                    oli.qty_invoiced__c = oi.qty_invoiced__c;
                    oli.qty_ordered__c = oi.qty_ordered__c;
                    oli.qty_refunded__c = oi.qty_refunded__c;
                    oli.qty_returned__c = oi.qty_returned__c;
                    oli.qty_shipped__c = oi.qty_shipped__c;
                    oli.Sku__c = oi.Sku__c; 
                    oliList.add(oli);
                    System.debug('--- Inside Opportunity' + opp);
                    System.debug('--- Oli List: ---');
                }
            }
        }
        try {
            if(oliList.size()>0) {
                insert oliList;
                System.debug('--- Inserted Opp Line Items: ---');
                System.debug('--- Inserted Opp Line Items: ---' + olilist.size()); 
            }
        }
        catch(Exception e){
            System.debug('The Following Exception has occurred: '+ e.getLinenumber() + ' : ' + e.getMessage());
        }
    }
}

Need assistance to complete this code.

Thanks.
