• What is the cause and solution for SAP error message /UI5/DESCRIPTOR_MERG003 - Change type &1 not supported for descriptor changes on non app variants ?

  The SAP error message /UI5/DESCRIPTOR_MERG003 Change type &1 not supported for descriptor changes on non app variants typically occurs in the context of SAP Fiori/UI5 applications when there are issues related to the deployment or modification of application descriptors, particularly when dealing with non-app variants.
  Cause:
  This error message indicates that there is an attempt to apply a change type that is not supported for the specific context of non-app variants. Non-app variants refer to configurations or settings that are not tied to a specific application but rather to a broader context, such as a theme or a global setting. The change types that are typically supported for app variants (like adding or modifying UI5 application descriptors) may not be applicable to non-app variants.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Change Types: Check the change type you are trying to apply. Ensure that it is appropriate for the context of non-app variants. You may need to use a different change type that is supported for non-app variants.
  
  
  Check Configuration: Verify the configuration settings in your SAP system. Ensure that the non-app variant you are trying to modify is correctly set up and that you are not inadvertently trying to apply changes that are meant for app variants.
  
  
  Use App Variants: If your changes are intended for a specific application, consider creating or using an app variant instead of a non-app variant. This may involve creating a new app variant or modifying an existing one.
  
  
  Consult Documentation: Refer to the official SAP documentation for UI5 and Fiori regarding change management and descriptor changes. This can provide insights into supported change types and best practices.
  
  
  SAP Notes and Support: If the issue persists, check for any relevant SAP Notes that may address this specific error. You can also reach out to SAP support for assistance.
