• What is the cause and solution for SAP error message /SCWM/ERPINTEGRATION836 - Another PPF action of same kind is already running ?

  The SAP error message /SCWM/ERPINTEGRATION836 indicates that there is an attempt to execute a Post Processing Framework (PPF) action that is already in progress. This typically occurs in the context of SAP Extended Warehouse Management (EWM) when multiple processes try to trigger the same PPF action simultaneously.
  Cause:
  
  
  Concurrent Execution: The most common cause is that the same PPF action is being triggered multiple times concurrently. This can happen due to:
  
  Multiple users or processes trying to execute the same action.
  A system or configuration issue that causes the action to be retried automatically.
  A long-running process that has not yet completed.
  
  
  
  Locking Mechanism: SAP uses a locking mechanism to prevent the same action from being executed simultaneously. If one instance of the action is still running, any subsequent attempts to start the same action will be blocked, leading to this error.
  
  
  Solution:
  
  
  Check Running Processes: 
  
  Use transaction codes like SM37 (Job Monitoring) or SM21 (System Log) to check for any running jobs or processes related to the PPF action.
  Identify if there is an ongoing instance of the same PPF action and wait for it to complete.
  
  
  
  Review PPF Configuration:
  
  Check the configuration of the PPF action in transaction /SCWM/PPF to ensure that it is set up correctly and that there are no issues with the action definition.
  
  
  
  Increase Timeout or Adjust Settings:
  
  If the action is taking too long to complete, consider optimizing the process or increasing the timeout settings if applicable.
  
  
  
  Manual Intervention:
  
  If a process is stuck, you may need to manually terminate it. This should be done with caution and typically requires administrative privileges.
  
  
  
  Error Handling:
  
  Implement error handling in your processes to manage retries or to prevent multiple triggers of the same action.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to PPF actions for any specific recommendations or known issues.
  
  
  
  Related Information:
  
  PPF Actions: Understand the specific PPF actions that are being triggered and their implications on the warehouse processes.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide patches or updates.
  System Performance: Monitor system performance to ensure that it is not causing delays in the execution of PPF actions.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or EWM support team for further investigation.
