• What is the cause and solution for SAP error message CNV_PE823 - Wait while data is still loading ?

  The SAP error message "CNV_PE823 Wait while data is still loading" typically occurs during data migration or data transfer processes, particularly when using SAP's data migration tools or during the execution of a conversion program. This message indicates that the system is still processing data and that the user should wait until the operation is complete.
  Cause:
  
  Long Processing Time: The data being processed is large, and the system is taking longer than expected to load or convert the data.
  System Performance: The performance of the SAP system may be affected by various factors, such as high system load, insufficient resources (CPU, memory, disk I/O), or network issues.
  Locks or Deadlocks: Other processes may be locking the data or resources needed for the migration, causing delays.
  Configuration Issues: Incorrect configuration settings in the data migration tool or the SAP system can lead to inefficiencies in data processing.
  
  Solution:
  
  Wait for Completion: Often, the simplest solution is to wait for the process to complete. If the operation is still running, it may eventually finish without further intervention.
  Monitor System Performance: Use transaction codes like ST03N (Workload Analysis) or SM66 (Global Work Process Overview) to monitor system performance and identify any bottlenecks.
  Check for Locks: Use transaction code SM12 to check for any locks that may be affecting the data loading process. If you find locks that are not needed, you may release them.
  Review Logs: Check the logs for the data migration process (e.g., using transaction SLG1) to identify any specific errors or warnings that may provide more context on the issue.
  Optimize Data Load: If the data volume is too large, consider breaking it into smaller batches to improve processing time.
  System Resources: Ensure that the SAP system has adequate resources (CPU, memory, etc.) allocated to handle the data load efficiently.
  Configuration Review: Review the configuration settings for the data migration tool to ensure they are optimized for your specific scenario.
  
  Related Information:
