• What is the cause and solution for SAP error message CNVMBTPEM028 - Called dequeue for &1. ?

  The SAP error message CNVMBTPEM028 typically relates to issues encountered during the execution of a data migration or conversion process, particularly when using the SAP Landscape Transformation (SLT) or SAP Data Services. The message indicates that there was a problem with the dequeue operation for a specific object or resource.
  Cause:
  The error message CNVMBTPEM028 Called dequeue for &1 can occur due to several reasons, including:
  
  
  Locking Issues: The object or resource that the process is trying to access is currently locked by another process. This can happen if multiple processes are trying to access the same data simultaneously.
  
  
  Transaction Rollback: If a previous transaction failed or was rolled back, it might leave the system in a state where the dequeue operation cannot be completed.
  
  
  System Performance: High system load or performance issues can lead to timeouts or failures in processing dequeue requests.
  
  
  Configuration Issues: Incorrect configuration settings in the migration or transformation process can lead to errors in resource handling.
  
  
  Solution:
  To resolve the CNVMBTPEM028 error, you can try the following steps:
  
  
  Check Locks: Use transaction code SM12 to check for any locks on the object/resource that is causing the issue. If you find any unnecessary locks, you can delete them (ensure that you have the necessary authorizations and that it is safe to do so).
  
  
  Review Logs: Check the application logs (transaction code SLG1) for more detailed error messages that can provide additional context about the failure.
  
  
  Restart the Process: If the error occurred during a migration or transformation process, try restarting the process after ensuring that no locks are present.
  
  
  System Performance: Monitor system performance and resource usage. If the system is under heavy load, consider scheduling the migration process during off-peak hours.
  
  
  Configuration Review: Review the configuration settings for the migration or transformation process to ensure they are set up correctly.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches or updates.
  
  
  Consult Documentation: Refer to the official SAP documentation for the specific tools you are using (e.g., SLT, Data Services) for any additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (for locks), SLG1 (for application logs), and ST22 (for dumps).
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance, providing them with detailed logs and error messages for better diagnosis.
