Hello, I have Salesforce to Salesforce setup and I'm trying to share opportunity records and opportunity products with the target org. We want to be able to manually share the opportunity record with by using the standard external sharing button with S2S. However, we would like to automatically send over opportunity products on any opportunities that we are sharing between the two orgs. Below is the code that I have to try to automatically send over the opp producst but it's not inserting or updating in the target org. Any assistance is appreciated. Thank you.
