• What is the cause and solution for SAP error message /UI2/CDMCNV531 - App Targer &1: Duplicate inbound ID &2 ?

  The SAP error message /UI2/CDMCNV531 App Target &1: Duplicate inbound ID &2 typically occurs in the context of SAP Fiori applications and the SAP UI5 framework. This error indicates that there is a duplicate inbound ID for a specific application target, which can lead to conflicts when the system tries to process requests.
  Cause:
  
  
  Duplicate Inbound ID: The error is primarily caused by having multiple entries with the same inbound ID in the configuration of the Fiori Launchpad or in the application routing settings. This can happen if:
  
  The same application is registered multiple times with the same inbound ID.
  There are inconsistencies in the application configuration or transport requests that have not been properly managed.
  
  
  
  Configuration Issues: Incorrect or incomplete configuration in the Fiori Launchpad or the underlying OData services can also lead to this error.
  
  
  Solution:
  
  
  Check Fiori Launchpad Configuration:
  
  Go to the Fiori Launchpad configuration (transaction code: /UI2/FLP or /UI2/FLP_CONFIG).
  Look for the application target with the specified inbound ID (&2 in the error message).
  Ensure that there are no duplicate entries for the same inbound ID. If duplicates are found, remove or correct them.
  
  
  
  Review Application Registration:
  
  Check the application registration in the SAP system (transaction code: /UI2/FLP).
  Ensure that each application has a unique inbound ID and that there are no conflicting entries.
  
  
  
  Transport Requests:
  
  If the issue arose after a transport, check the transport requests to ensure that they did not introduce duplicate entries.
  If necessary, adjust the transport requests to remove duplicates.
  
  
  
  Clear Cache:
  
  Sometimes, clearing the cache can help resolve issues related to configuration changes. You can clear the cache using transaction code: /UI2/FLP and then selecting the option to clear the cache.
  
  
  
  Check OData Services:
  
  If the application relies on OData services, ensure that the services are correctly defined and do not have overlapping configurations.
