• What is the cause and solution for SAP error message WTY121 - Error occurred when VSR checks were called at call-up point &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WTY121 - Error occurred when VSR checks were called at call-up point &1
  
  Meaning / Cause:
  
  WTY121 is an error related to the Vehicle Scheduling and Routing (VSR) functionality in SAP.
  The message indicates that an error occurred during the execution of VSR checks at a specific call-up point (the placeholder &1 is replaced by the actual call-up point ID or name).
  This usually happens when the system tries to validate or process data related to vehicle scheduling, routing, or transportation planning, and the checks fail due to inconsistent or missing data, or due to a problem in the custom or standard VSR check routines.
  Possible causes include:
  
  Incorrect or incomplete master data for the call-up point (e.g., missing address, transportation zone, or scheduling parameters).
  Custom VSR check routines (user exits or BADIs) that raise an error or exception.
  Configuration issues in the VSR settings.
  Data inconsistencies in the transportation planning or scheduling data.
  
  
  
  
  Solution / How to Fix:
  
  
  Check the Call-up Point Data:
  
  Verify the master data for the call-up point mentioned in the error.
  Ensure all required fields (address, transportation zone, scheduling parameters) are correctly maintained.
  Use transaction codes like /SCMTMS/LOC or relevant VSR master data transactions to review and correct data.
  
  
  
  Review VSR Check Routines:
  
  If custom VSR checks are implemented (via user exits or BADIs), review the code to identify why the error is raised.
  Debug the process to see what condition triggers the error.
  Correct any logical errors or data assumptions in the custom code.
  
  
  
  Check Configuration:
  
  Review the VSR configuration in SPRO under Transportation Management ? Vehicle Scheduling and Routing ? Checks and Validations.
  Ensure that the checks are properly configured and that no mandatory parameters are missing.
  
  
  
  Analyze Logs and Dumps:
  
  Check the short dump (ST22) or application logs (SLG1) for more detailed error information.
  This can provide clues about the exact cause of the failure.
  
  
  
  Test with Different Data:
  
  Try to reproduce the error with different call-up points or scheduling data to isolate whether the problem is data-specific or systemic.
  
  
  
  SAP Notes and Support:
  
  Search for SAP Notes related to WTY121 for any known issues or patches.
  If the problem persists, consider raising a support ticket with SAP, providing detailed logs and steps to reproduce.
