This problem analyzer removes standard objects and fields that reference features that aren't enabled in the target environment.
What triggers this problem analyzer?
Selecting standard objects or fields that exist in the source but not in the target, with the difference type of New, will trigger this analyzer.
You'll see a message in Gearset suggesting that you "Remove standard objects and fields".
What problem is it solving?
When certain features are enabled in an org, they also create new standard objects and fields. These items can't be deployed into a target environment that doesn't already have these features enabled.
If you try to deploy a new standard object into an org that doesn't have the features enabled, your validation will fail.
There are two ways to resolve this issue:
Remove the standard objects and fields from your deployment package (by accepting Gearset's problem analyzer suggestion); or
Enable the features in your target environment via the Salesforce UI, and re-run the deployment
How does it work?
Gearset will automatically remove any new standard objects and fields from your deployment package.
