• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK312 - Proxy Data Type &1 does not exist ?

  The SAP error message CFD_REGISTRY_CHECK312 indicates that there is an issue with a proxy data type that the system is trying to access, which does not exist in the registry. This error typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when dealing with web services or proxy communication.
  Cause:
  
  
  Missing Proxy Data Type: The specified proxy data type (indicated by &1 in the error message) is not defined in the system. This could be due to a number of reasons, such as:
  
  The proxy was not generated correctly.
  The proxy data type was deleted or not activated.
  There is a mismatch between the service definition and the actual implementation.
  
  
  
  Incorrect Configuration: The configuration settings for the service or the communication channel may be incorrect, leading to the system looking for a non-existent data type.
  
  
  Transport Issues: If the proxy was transported from one system to another, it may not have been included in the transport request, or the transport may have failed.
  
  
  Solution:
  
  
  Check Proxy Generation:
  
  Ensure that the proxy data type is generated correctly. You can regenerate the proxy by going to the relevant transaction (e.g., SPROXY) and checking the proxy object.
  
  
  
  Activate the Proxy:
  
  If the proxy data type exists but is not activated, activate it in the relevant namespace.
  
  
  
  Verify Configuration:
  
  Check the configuration settings in the Integration Directory or the relevant configuration area to ensure that the correct proxy is being referenced.
  
  
  
  Check Transport Requests:
  
  If the proxy was transported, verify that the transport request included all necessary objects. You may need to re-transport the missing objects.
  
  
  
  Check for Naming Conventions:
  
  Ensure that there are no naming convention issues or discrepancies between the sender and receiver systems.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the process to identify where the system is failing to find the proxy data type.
