• What is the cause and solution for SAP error message ATP_RELFORDEL202 - Parallel delivery creation is already running. ?

  The SAP error message ATP_RELFORDEL202, which states "Parallel delivery creation is already running," typically occurs in the context of Advanced Planning and Optimization (APO) or when using the Available-to-Promise (ATP) functionality in SAP. This error indicates that there is already a process running that is attempting to create deliveries in parallel, which can lead to conflicts or data integrity issues.
  Cause:
  
  
  Concurrent Processes: The error is primarily caused by multiple processes trying to create deliveries at the same time. This can happen if:
  
  Multiple users or jobs are attempting to create deliveries simultaneously.
  A background job is already running that is responsible for delivery creation.
  
  
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If one process has locked the delivery creation function, other processes will be blocked until the first one completes.
  
  
  Solution:
  
  
  Check Running Processes: 
  
  Use transaction codes like SM66 (Global Work Process Overview) or SM50 (Work Process Overview) to check for any active processes that might be creating deliveries.
  Identify and monitor the process that is currently running.
  
  
  
  Wait for Completion: If you find that a process is running, you may need to wait for it to complete before attempting to create deliveries again.
  
  
  Review Background Jobs: 
  
  Check if there are any scheduled background jobs that might be causing the issue. Use transaction code SM37 to view job logs and statuses.
  If a job is stuck or taking too long, you may need to analyze it further or terminate it if necessary.
  
  
  
  Increase Parallel Processing Limits: If the business process requires multiple deliveries to be created in parallel, consider reviewing and adjusting the configuration settings for parallel processing in your SAP system.
  
  
  Error Handling: Implement error handling in your delivery creation process to manage situations where this error might occur, such as retry mechanisms or notifications.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error. Sometimes, SAP releases notes that address known issues or provide guidance on configuration changes.
  Documentation: Review the SAP documentation related to ATP and delivery creation processes to understand the best practices and configurations.
  System Performance: Ensure that your system is adequately resourced to handle the expected load, as performance issues can exacerbate locking and concurrency problems.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis team or reach out to SAP support for further assistance.
