• What is the cause and solution for SAP error message WGDS_PROCESS685 - Processing CINs sequentially that were not be able to process in parallel ?

  The SAP error message WGDS_PROCESS685: Processing CINs sequentially that were not able to process in parallel typically occurs in the context of SAP Global Trade Services (GTS), specifically during the processing of Customs Item Numbers (CINs) in customs declaration or compliance processes.
  
  Cause
  
  Parallel processing of CINs failed: The system initially attempts to process multiple CINs in parallel to improve performance. However, some CINs cannot be processed in parallel due to dependencies, locks, or data inconsistencies.
  Sequential fallback: When parallel processing fails for certain CINs, the system falls back to processing these CINs sequentially to ensure data integrity and avoid conflicts.
  Underlying reasons for failure in parallel processing include:
  
  Data locks or database contention on CIN-related tables.
  Dependencies between CINs that require sequential handling.
  Inconsistent or incomplete data in CIN records.
  System resource constraints or timeout issues during parallel execution.
  
  
  
  
  Solution
  
  
  Check system logs and dumps:
  
  Review the short dumps (transaction ST22) and system logs (SM21) for related errors or lock entries.
  Identify if there are database locks or deadlocks causing parallel processing to fail.
  
  
  
  Analyze CIN data consistency:
  
  Verify the integrity and completeness of the CIN data.
  Use transaction codes related to CIN processing (e.g., /SAPSLL/CIN* transactions) to check for inconsistencies.
  
  
  
  Adjust parallel processing settings:
  
  In some cases, you can configure or limit the number of parallel processes in the customizing settings for CIN processing.
  This can be done in the GTS customizing under Customs Management ? Processing ? Parallel Processing Settings.
  
  
  
  Apply SAP Notes and Patches:
  
  Check for relevant SAP Notes that address issues with CIN parallel processing.
  SAP often releases corrections for performance and processing logic in GTS components.
  
  
  
  Monitor system performance:
  
  Ensure that the system has adequate resources (CPU, memory) to handle parallel processing.
  Optimize database performance and reduce contention.
  
  
  
  Fallback handling:
  
  The message itself indicates the system is handling the issue by switching to sequential processing, which is a safe fallback.
  If sequential processing completes successfully, the issue is mitigated but may impact performance.

  SAP GTS (Global Trade Services): The error is specific to GTS customs processing.
  CIN (Customs Item Number): Represents individual items or positions in customs declarations.
  Parallel Processing: Used to speed up processing of multiple CINs but requires careful handling of dependencies.
  Transactions and Tools:
  
  /SAPSLL/CIN_PROCESS or similar for CIN processing.
  ST22 for dumps.

  Summary
  
  Cause: Parallel processing of CINs failed due to locks, dependencies, or data issues.
  Effect: System falls back to sequential processing to maintain data integrity.
  Solution: Investigate locks, data consistency, system resources, adjust parallel processing settings, and apply SAP Notes.
  Impact: Sequential processing is slower but ensures correctness.
