Hi,
I am trying to update a newly created quote with the line items from the opportuntiy it was created on.

This is for annual opportunities for support contracts and I have used a flow to create the new opportunity when it reaches 30 days before its close date which works fine.  I then got stuck trying to create the quote, add the line items and also create a pdf template of the quote, so turned to try and do it via triggers.

So far, once the new opportunity is created, I have a trigger to create a new quote......how do I now update that quotes line items with the opportunity line items.  Heres what I have so far and an new to development with apex and struggling as can be seen withthe mess below of how far away I am...: -


trigger addquotelineitems on Quote (after insert) {

Quote qot =trigger.new[0];
 
Opportunity oppId=[select id from Opportunity where id=:qot.OpportunityId];
 
List<OpportunityLineItem> opplines=[select id, quantity, PriceBookEntry.Product2Id
from OpportunityLineItem where OpportunityId=:oppId.id];
 
    for(OpportunityLineItem oppline:opplines){
         
        QuoteLineItem qli = new QuoteLineItem();
        qli.UnitPrice = oppline.UnitPrice;
        qli.Product2Id = oppline.PriceBookEntry.Product2Id;
        qli.Quantity = oppline.Quantity;
        qli.Description = oppline.Description;
        insert qli;
    }
 
}

After that I need to create a quote pdf using a template, but no idea if this is possible let alone how its done, I guess via a class or some sort

Thanks
