Hi!
I registered with trailhead.
I’m an SDR looking to expand my Salesforce skill set. Let’s pretend I have none. Particularly looking for the basics around reporting, and any other trails that may be beneficial to spend some time with.
My goal is to have a competent understanding of SF to build my sales as I enter a closing role and the relevant tools in SF that will help me gain an advantage.
Thanks in advance!

Hello everyone,

The SalesForce REST API doc is unclear about the usage of APIs to insert and update records in OpportunityLineItem. The standard fields in OLI include OpportunityId and Product2Id both of which I'm populating by retrieving the appropriate SalesForce IDs. I receive this error: INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY when I try to insert a record at this URI: /sobjects/OpportunityLineItem/.

Going through the flow: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_erd_products.htm#topic-title, I'm assuming this (and also the cross-reference error) means that there is no direct relationship between OLI and Products.

Firstly, why is there a Product2Id field if the relationship doesn't exist?
Secondly, is the URI I'm using incorrect? If so, what is the correct one?
Thirdly, can this problem be solved using APIs at all?

Maybe I'm going about this in a completely inefficient manner. Any suggestions would be greatly appreciated.

Has anyone completed this trail? I am stomped on challenge number 3, regarding created the process for fulfillment. Any pointers or guidance would be appreciated.
