• What is the cause and solution for SAP error message /UI2/CDMFCC017 - The UI5 component name &1 is not unique. App ID &2 ?

  The SAP error message /UI2/CDMFCC017 indicates that there is a conflict with the UI5 component name in the SAP Fiori application. Specifically, it means that the UI5 component name specified is not unique within the context of the application ID provided. This can occur when multiple components are registered with the same name, leading to ambiguity in the application.
  Cause:
  
  
  Duplicate Component Names: The most common cause of this error is that there are multiple UI5 components with the same name registered in the system. This can happen if:
  
  Two different applications are using the same component name.
  There are multiple versions of the same component deployed.
  There is a misconfiguration in the application descriptor files (e.g., manifest.json).
  
  
  
  Incorrect Application ID: The application ID provided may not correctly point to the intended component, leading to confusion in the system.
  
  
  Solution:
  
  
  Check Component Registration:
  
  Review the components registered in the system. You can do this by checking the SAP Fiori Launchpad or the SAP Web IDE to see if there are any duplicate component names.
  Ensure that each component has a unique name.
  
  
  
  Modify Component Names:
  
  If you find duplicate component names, consider renaming one of the components to ensure uniqueness. This may involve updating the manifest.json file of the affected application.
  
  
  
  Review Application ID:
  
  Verify that the application ID you are using is correct and corresponds to the intended component. Ensure that it is not pointing to a different or incorrect application.
  
  
  
  Clear Cache:
  
  Sometimes, caching issues can lead to this error. Clear the browser cache and the SAP Fiori Launchpad cache to ensure that the latest versions of the components are being loaded.
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, ensure that the transport did not inadvertently overwrite or duplicate components.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for guidelines on naming conventions and component registration to avoid future conflicts.
