• What is the cause and solution for SAP error message JIT00577 - Summarized JIT call delivery created not supported in parallel session ?

  The SAP error message JIT00577, which states "Summarized JIT call delivery created not supported in parallel session," typically occurs in the context of Just-In-Time (JIT) delivery processes within SAP. This error indicates that there is an attempt to process JIT call deliveries in parallel sessions, which is not supported by the system.
  Cause:
  
  Parallel Processing: The error arises when multiple sessions or transactions are trying to create or process JIT call deliveries simultaneously. SAP does not allow this due to potential data inconsistencies or conflicts that can arise from concurrent processing.
  Session Management: The user may have multiple sessions open in SAP, and the system is trying to execute JIT delivery processes in more than one session at the same time.
  
  Solution:
  
  Single Session Usage: Ensure that you are working in a single session when processing JIT call deliveries. Close any additional sessions that may be open.
  Sequential Processing: If you need to process multiple JIT deliveries, do so sequentially rather than in parallel. Wait for one process to complete before starting another.
  Check for Background Jobs: If there are background jobs or batch processes that might be interfering, check the job status and ensure they are not running concurrently with your manual processes.
  System Configuration: If this issue persists, it may be necessary to review the system configuration or consult with your SAP Basis team to ensure that the system is set up correctly for JIT processing.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error. SAP Notes can often provide specific fixes or workarounds.
  Documentation: Review the SAP documentation related to JIT processing to understand the limitations and best practices for handling JIT deliveries.
  User Training: Ensure that users involved in JIT processing are trained on the proper procedures to avoid parallel processing issues.
