Issue
The issue appears when a custom view is created in MSI that contains dependant fields.
The error message: "The dependent picklist '<dependant field name>' requires its controlling field '<parent field>' to be present on the page." will be displayed when you are trying to add the dependant field.
For example: "The dependent picklist 'Sub-Classification' requires its controlling field 'Classification' to be present on the page."
Environment
Salesforce
MSI
Solution
Need to omit the dependant field in the custom view.
Root Cause
We curently do not support creating a view in SFDC MSI with a dependant field.
