• What is the cause and solution for SAP error message WZ395 - No tag found for the XML message type (for example, request) ?

  SAP Error Message:
  
  WZ395 No tag found for the XML message type (for example, request)
  
  Cause
  This error occurs during XML message processing in SAP PI/PO or SAP XI when the system tries to parse or process an XML message but cannot find the expected XML tag corresponding to the message type (e.g., request, response, etc.). Essentially, the XML message structure does not match the expected format defined in the message mapping or the XML schema.
  Common causes include:
  
  The incoming XML message is malformed or missing the root tag or expected elements.
  The message type in the interface or mapping does not correspond to the actual XML message structure.
  Incorrect or missing namespace declarations in the XML message.
  The message mapping or operation mapping expects a certain tag (like <request>) but the actual message uses a different tag or no tag at all.
  The adapter or communication channel is not configured correctly, causing the message to be altered or truncated.
  
  
  Solution
  
  
  Check the XML Message Structure:
  
  Verify the actual XML message payload being sent to SAP.
  Ensure that the root tag and child elements match the expected message type (e.g., <request>, <response>, etc.).
  Use transaction SXMB_MONI or the message monitoring tool to view the payload.
  
  
  
  Validate Against the XML Schema:
  
  Confirm that the XML message conforms to the XSD schema used in the interface.
  Check for missing or incorrect namespaces.
  
  
  
  Review Message Mapping and Operation Mapping:
  
  Ensure that the mapping expects the correct root tag.
  If the mapping expects <request>, but the message uses <Request> or another tag, adjust the mapping or the sender system accordingly.
  
  
  
  Check Adapter and Channel Configuration:
  
  Verify that the adapter (e.g., SOAP, IDoc, File) is configured correctly and does not modify the message structure.
  For SOAP, check the SOAP action and message type settings.
  
  
  
  Correct the Sender System:
  
  If the sender system sends an incorrect or incomplete XML message, fix the message generation logic.
  
  
  
  Test with a Sample XML:
  
  Use a sample XML message that matches the expected structure to test the interface.

  Summary
  The error WZ395 No tag found for the XML message type indicates a mismatch between the expected XML tag in the message processing and the actual XML message received. The solution involves verifying and correcting the XML message structure, ensuring proper namespaces, and aligning the sender message with the expected format in SAP.
  
  If you provide the actual XML message and the interface/mapping details, I can help you pinpoint the exact mismatch.
