I have what looks like a standard field OpportunityLineItem.Name in my sandbox.
When I compare the sandbox with the production org using Gearset, it identifies the field is missing, but won't let me deploy it:
When I try and create a normal change set, I cannot seem to select it as a field.
The Name is a standard field on OpportunityLineItem and it will be available by default in the org. You can refer soap api guide here.
The opportunity line item name (known as “Opportunity Product” in the user interface). This read-only field is available in API version 30.0 and later.
The changeset will not have capability to deploy standard objects according to this idea.
I have tried fetching OpportunityLineItem metadata using SFDX, It does not return the Name field.
These are my findings on deploying Name field.
I was able to update the name and saw the difference in gearset for OpportunityLineItem.Name field between 2 orgs.PFB.
So it depends upon whats changed in your field. In case there is no difference between 2 orgs for that field, Gearset does not show the field itself.
Regarding your second option of change set, i also was not able to find this field while creating the changeset.
I raised a case with Salesforce support, and was told that OpportunityLineItem.Name is only available in the sandbox because it is a Winter 21 sandbox preview.
