• What is the cause and solution for SAP error message WZRE_PRX158 - Error in method &1: payload data are not found ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_PRX158 Error in method &1: payload data are not found
  
  Cause:
  This error typically occurs in the context of SAP PI/PO (Process Integration/Process Orchestration) or SAP CPI (Cloud Platform Integration) when a proxy or adapter method expects certain payload data but does not find it. The placeholder &1 is replaced by the method name where the error occurred.
  Common causes include:
  
  The payload sent to the proxy or adapter is empty or missing.
  The message processing logic expects payload data that was not delivered or was lost during message transformation or routing.
  Incorrect configuration of the sender or receiver channels leading to no payload being passed.
  Issues in the mapping or adapter modules that result in an empty payload.
  The message was filtered out or removed by some prior step in the integration flow.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the Payload:
  
  Verify that the message payload is correctly generated and passed to the method mentioned in the error.
  Use SAP PI/PO message monitoring or CPI message monitoring to inspect the payload at various steps.
  
  
  
  Review Integration Flow or Scenario:
  
  Ensure that the sender system is sending the payload correctly.
  Check the configuration of sender and receiver adapters/channels to confirm that payload data is not lost or filtered out.
  
  
  
  Check Mapping and Adapter Modules:
  
  Validate any message mappings or adapter modules that might manipulate the payload.
  Ensure that these do not inadvertently remove or clear the payload.
  
  
  
  Debug or Trace:
  
  Enable trace or debug logs for the integration engine or proxy runtime to get more detailed information about where the payload is lost.
  In SAP PI/PO, use the Runtime Workbench or Integration Engine traces.
  In SAP CPI, use the message processing logs.
  
  
  
  Check for Filters or Conditions:
  
  Verify if any filters or conditions in the integration flow are causing the payload to be dropped.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes or Knowledge Base Articles (KBAs) for your specific SAP version and scenario.
  
  
  
  
  Related Information:
  
  SAP PI/PO Proxy Runtime: The error is often related to proxy runtime processing where the method expects payload data.
  Integration Engine: Payload data is essential for message processing; missing payload leads to such errors.
  Message Monitoring: Use transaction codes like SXMB_MONI (for PI/PO) or the SAP CPI Web UI to monitor messages.
