  SAP Error Message:
  WZRE_PRX004 - Severe error during mapping inbound (class &1, method &2)
  
  Cause:
  This error occurs during the inbound IDoc processing when the system tries to execute a mapping routine (usually in a proxy or PI/PO scenario) and encounters a severe runtime error in the specified ABAP class and method. The placeholders &1 and &2 represent the class name and method name where the error occurred.
  Common causes include:
  
  Programming errors in the ABAP class/method used for mapping (e.g., null pointer, division by zero, unhandled exceptions).
  Incorrect or unexpected data in the inbound IDoc or message payload causing the mapping logic to fail.
  Missing or incorrect configuration in the mapping or proxy setup.
  Authorization issues or missing objects required by the mapping logic.
  System or runtime environment issues such as memory problems or locked objects.
  
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify the Class and Method:
  
  Check the error message details to find the exact class (&1) and method (&2) where the error occurred.
  Use transaction SE24 (Class Builder) or SE80 to inspect the class and method code.
  
  
  
  Analyze the Error:
  
  Debug the inbound processing by setting breakpoints in the identified method.
  Use transaction WE02 or WE05 to view the inbound IDoc data that caused the error.
  Check for any unusual or unexpected data values that might cause the mapping logic to fail.
  
  
  
  Check System Logs:
  
  Use transaction ST22 to check for any short dumps related to the error.
  Use transaction SM21 for system logs that might provide additional clues.
  
  
  
  Review Mapping Logic:
  
  Verify the ABAP code for proper error handling.
  Add necessary checks to handle unexpected or missing data gracefully.
  Ensure all required authorizations and objects are available.
  
  
  
  Test with Correct Data:
  
  Try processing a known good IDoc/message to confirm if the error is data-related.
