• What is the cause and solution for SAP error message WGDS_PROCESS657 - Error while starting parallel processing (Sy-Subrc = &1) ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WGDS_PROCESS657 - Error while starting parallel processing (Sy-Subrc = &1)
  
  Cause:
  This error occurs during the execution of a parallel processing task in SAP, specifically when the system tries to start a parallel process (e.g., a background job or a parallel RFC call) and fails. The Sy-Subrc value returned indicates the type of failure encountered when attempting to initiate the parallel process.
  Common causes include:
  
  System resource limitations: Insufficient work processes or background processes available to start the parallel task.
  Incorrect or missing configuration: Parallel processing framework or related settings are not properly configured.
  Authorization issues: The user or process does not have the necessary authorizations to start parallel jobs.
  Technical problems: Network issues, RFC destination problems, or system load causing failure to spawn parallel tasks.
  Programming errors: Incorrect handling of parallel processing calls in custom code or standard SAP programs.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the Sy-Subrc value:
  
  The message includes Sy-Subrc = &1. Check the actual return code to understand the specific failure cause. Common return codes and their meanings can be found in SAP documentation or by debugging.
  
  
  Verify system resources:  
  
  Check the number of available dialog and background work processes (SM50, SM66, SM37).
  Ensure there are enough free work processes to start parallel jobs.
  If necessary, increase the number of background or dialog work processes in system profile parameters.
  
  
  
  Check RFC destinations:  
  
  If parallel processing involves RFC calls, verify the RFC destinations are correctly configured and active (SM59).
  Test the RFC connections to ensure they are working.
  
  
  
  Review authorizations:  
  
  Ensure the user executing the parallel process has the required authorizations.
  Check roles and profiles assigned to the user.
  
  
  
  Check system logs and dumps:  
  
  Look into system logs (SM21) and short dumps (ST22) for related errors.
  Analyze any runtime errors that might give more clues.
  
  
  
  Debug the program:  
  
  If this error occurs in custom code, debug the parallel processing calls to identify the exact failure point.
  Ensure that the parallel processing framework is used correctly.
