• What is the cause and solution for SAP error message /UI5/MP_CA003 - Descriptor changes are not allowed for app &1 ?

  The SAP error message /UI5/MP_CA003 Descriptor changes are not allowed for app &1 typically occurs in the context of SAP Fiori applications when there are attempts to modify the application descriptor (manifest.json) of a deployed application. This error indicates that the application is in a state where changes to its descriptor are not permitted, often due to the application being in a production environment or because of specific restrictions set by the system.
  Cause:
  
  Production Environment: The application is deployed in a production environment where changes to the application descriptor are restricted to ensure stability and reliability.
  Transport Layer Restrictions: The application might be locked in the transport layer, preventing any modifications.
  Version Control: The application might be version-controlled, and changes to the descriptor are not allowed without following specific procedures.
  User Permissions: The user attempting to make changes may not have the necessary permissions to modify the application descriptor.
  
  Solution:
  
  Check Environment: Ensure that you are working in a development or test environment where changes are allowed. If you need to make changes in production, consider deploying a new version of the application.
  Transport Request: If the application is part of a transport request, ensure that the transport is released and that you have the necessary permissions to make changes.
  Permissions: Verify that you have the appropriate authorizations to modify the application descriptor. You may need to contact your system administrator for assistance.
  Versioning: If the application is version-controlled, follow the proper procedures for updating the application, which may involve creating a new version rather than modifying the existing one.
  Consult Documentation: Refer to the SAP documentation for guidelines on managing application descriptors and the specific restrictions that may apply to your environment.
