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."
Need to omit the dependant field in the custom view.
We curently do not support creating a view in SFDC MSI with a dependant field.
