• What is the cause and solution for SAP error message /UI2/CDMCNV402 - Skipping component: No Mapping Entries found ?

  The SAP error message /UI2/CDMCNV402 Skipping component: No Mapping Entries found typically occurs in the context of SAP Fiori or UI5 applications when there is an issue with the component mapping in the SAP system. This error indicates that the system is unable to find the necessary mapping entries for a specific component, which can prevent the application from functioning correctly.
  Cause:
  
  
  Missing Mapping Entries: The most common cause is that the required mapping entries for the component in question are not defined in the system. This can happen if the application was not properly configured or if the necessary transport requests were not imported.
  
  
  Incorrect Configuration: There may be an issue with the configuration of the component in the SAP Fiori Launchpad or the underlying OData services.
  
  
  Transport Issues: If the application was recently transported from one system to another (e.g., from development to production), the mapping entries may not have been included in the transport.
  
  
  Version Mismatch: There could be a version mismatch between the UI5 libraries and the backend services, leading to missing mappings.
  
  
  Solution:
  
  
  Check Mapping Entries: Verify that the mapping entries for the component are correctly defined in the SAP system. You can do this by checking the relevant configuration in the SAP Fiori Launchpad Designer or the SAP Gateway.
  
  
  Create Missing Entries: If the mapping entries are missing, you may need to create them manually. This can involve defining the component in the Fiori Launchpad and ensuring that the correct OData services are mapped.
  
  
  Transport Requests: If the issue arose after a transport, ensure that all necessary transport requests have been imported correctly. Check the transport logs for any errors.
  
  
  Clear Cache: Sometimes, clearing the cache of the SAP Fiori Launchpad or the browser can resolve issues related to outdated mappings.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as this can resolve compatibility issues.
  
  
  Consult Documentation: Refer to the official SAP documentation for guidance on configuring components and mapping entries.
