• What is the cause and solution for SAP error message CKMLRUN126 - Maximum number of runs reached ?

  The SAP error message CKMLRUN126, which states "Maximum number of runs reached," typically occurs in the context of the Material Ledger (ML) during the execution of the material valuation process. This error indicates that the system has reached the maximum number of runs allowed for a particular process, which can happen during the execution of the CKMLRUN program (the program responsible for running the material ledger).
  Cause:
  
  Exceeding Maximum Runs: The error is triggered when the number of runs for a specific material valuation process exceeds the predefined limit set in the system configuration.
  Long-Running Processes: If the material valuation process is complex or involves a large volume of data, it may require multiple runs to complete, leading to this error.
  Configuration Settings: The maximum number of runs is defined in the system settings, and it may not be sufficient for the current workload.
  
  Solution:
  
  Check Configuration: Review the configuration settings for the Material Ledger in transaction code OMX1 or OMX2 to see if the maximum number of runs can be increased. You may need to consult with your SAP Basis or functional team to adjust these settings.
  Optimize the Process: If possible, try to optimize the material valuation process to reduce the number of runs required. This could involve breaking down the process into smaller batches or simplifying the valuation logic.
  Run in Background: If the process is being run in the foreground, consider running it in the background instead. This can sometimes help manage resource allocation better and avoid hitting the maximum run limit.
  Check for Locks: Ensure that there are no locks on the materials being processed that could be causing delays or additional runs.
  Monitor System Performance: Check system performance and resource availability. Sometimes, performance issues can lead to longer processing times and more runs than expected.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CKMLCP (Material Ledger Closing) and CKMLRUN (Material Ledger Run) for managing and monitoring material valuation processes.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Review SAP documentation on Material Ledger and related processes to understand the implications of the maximum run limit and best practices for managing material valuations.
