• What is the cause and solution for SAP error message /UI5/DESCRIPTOR_MERG001 - Change type &1 is only allowed in app confis ?

  The SAP error message /UI5/DESCRIPTOR_MERG001 Change type &1 is only allowed in app confis typically occurs in the context of SAP Fiori applications when there is an issue with the configuration of the application descriptor files (manifest.json) or when trying to make changes that are not permitted in the current context.
  Cause:
  
  Invalid Change Type: The error indicates that a specific change type (denoted by &1) is being attempted in a context where it is not allowed. This usually happens when trying to modify certain properties or settings in the application descriptor that are restricted to specific configurations or environments.
  Incorrect Configuration: The application might be trying to apply changes that are only valid in the application configuration (app confis) but are being attempted in a different context, such as a transport request or a different environment.
  Versioning Issues: There may be discrepancies between the versions of the application or the underlying libraries that are being used.
  
  Solution:
  
  Check Change Type: Review the change type you are trying to apply. Ensure that it is appropriate for the context in which you are working. If it is meant to be applied only in the app configuration, make sure you are in the correct environment.
  Modify in App Configuration: If the change is indeed meant to be made in the app configuration, navigate to the appropriate configuration settings in the SAP Fiori launchpad or the relevant development environment and apply the changes there.
  Review Manifest.json: Check the manifest.json file for any incorrect entries or configurations that might be causing the issue. Ensure that all properties are correctly defined and that you are not trying to change properties that are immutable in the current context.
  Consult Documentation: Refer to the SAP documentation for the specific version of the Fiori application you are working with. There may be specific guidelines or restrictions regarding the change types that can be applied.
  Transport Requests: If you are working with transport requests, ensure that the changes you are trying to make are allowed in the transport context. Some changes may need to be made directly in the development environment before being transported.
