• What is the cause and solution for SAP error message WZRE_PRX050 - Internal error: Interface proxy name could not be determined ?

  The SAP error message:
  WZRE_PRX050 Internal error: Interface proxy name could not be determined
  
  Cause
  This error typically occurs when the SAP system is unable to determine or find the interface proxy name during runtime. This can happen due to:
  
  Missing or incorrectly generated proxy objects in the SAP system.
  Inconsistencies or missing entries in the proxy repository.
  Issues with the service interface or WSDL used to generate the proxy.
  Transport or system inconsistencies where the proxy was not properly imported or activated.
  Incorrect or incomplete configuration in the SOA Manager or Integration Directory.
  Problems in the communication setup where the system expects a proxy interface but cannot resolve it.
  
  
  Explanation
  In SAP PI/PO or SAP NetWeaver systems, proxies are generated ABAP objects that represent external service interfaces. When a proxy is called, the system needs to resolve the proxy interface name to the corresponding ABAP class or interface. If this resolution fails, the system throws the WZRE_PRX050 error.
