Dynamics 365 Customization – Remove Related Tab on Form ; After the Dynamics 365 Wave 1 2020 release, the routing menu on the left has been added as tab to all forms as Related. You can perform the following operations in order to remove this tab in any form.

Note: This change works form-based and must be applied individually on each form.
