  Exit Edit Mode: The simplest solution is to save your changes and exit the edit mode before attempting to navigate to a different change instance. Ensure that all required fields are filled out and that you have saved your work.
  Check Change Instances: If you need to work with multiple change instances, consider closing the current instance and then opening the desired one. This may involve navigating back to the main menu or using the appropriate transaction codes.
  Review User Permissions: Ensure that your user role has the necessary permissions to access the change instances you are trying to navigate to. If not, contact your SAP administrator to adjust your permissions.
