Smart SAP Assistant

• What is the cause and solution for SAP error message SRT_WSP2503 - STCM '&1' does not cover source proxy '&2' and/or target proxy '&3' ?

  The SAP error message SRT_WSP2503 indicates that there is a configuration issue with the Web Service Proxy (WSP) settings in the SAP system. Specifically, it means that the Service Consumer (source proxy) and/or the Service Provider (target proxy) are not properly covered by the Service Interface Mapping (STCM) configuration.
  Cause:
  
  Missing or Incorrect Configuration: The source proxy and/or target proxy may not be correctly configured in the Service Interface Mapping (STCM). This can happen if the proxies are not defined in the system or if there is a mismatch in the configuration.
  Service Interface Not Mapped: The service interface that the source proxy is trying to call may not be mapped to the target proxy in the STCM.
  Version Mismatch: There may be a version mismatch between the source and target proxies, leading to the error.
  Transport Issues: If the proxies were recently transported from one system to another, the transport might not have included all necessary configurations.
  
  Solution:
  
  
  Check STCM Configuration:
  
  Go to transaction code STCM in the SAP GUI.
  Verify that the source proxy and target proxy are correctly defined and mapped.
  Ensure that the service interface for both proxies is correctly configured.
  
  
  
  Create or Update Mappings:
  
  If the mapping does not exist, create a new mapping for the source and target proxies.
  If the mapping exists but is incorrect, update it to ensure it covers the required proxies.
  
  
  
  Check Proxy Definitions:
  
  Use transaction SOAMANAGER to check the definitions of the source and target proxies.
  Ensure that the web service definitions are correct and that they match the expected interfaces.
  
  
  
  Check for Version Compatibility:
  
  Ensure that the versions of the source and target proxies are compatible. If there are version differences, you may need to update the proxies.
  
  
  
  Transport Issues:
  
  If the proxies were transported, ensure that all necessary objects and configurations were included in the transport request.
  Re-transport if necessary.
  
  
  
  Testing:
  
  After making the necessary changes, test the web service call again to ensure that the error is resolved.
