Smart SAP Assistant

• What is the cause and solution for SAP error message FMHIE_CHGCHK_CUST001 - Message pool is full, display messages ?

  The SAP error message FMHIE_CHGCHK_CUST001 indicates that the message pool is full, which means that the system has reached its limit for storing messages that need to be displayed to the user. This can occur in various scenarios, particularly when there are a large number of messages generated during a transaction or process.
  Cause:
  
  Message Pool Limit: SAP has a predefined limit for the number of messages that can be stored in the message pool. When this limit is reached, the system cannot store any additional messages, leading to this error.
  High Volume of Messages: If a transaction generates a high volume of messages (e.g., warnings, errors, or informational messages), it can quickly fill up the message pool.
  Configuration Issues: There may be configuration settings that are not optimized for the volume of messages being generated.
  
  Solution:
  
  
  Review and Optimize Messages:
  
  Analyze the transaction or process that is generating a high volume of messages. Determine if all messages are necessary and if some can be suppressed or logged differently.
  Consider adjusting the severity of messages (e.g., changing some from error to warning) if appropriate.
  
  
  
  Increase Message Pool Size:
  
  If feasible, consult with your SAP Basis team to see if the message pool size can be increased. This may involve adjusting system parameters in the SAP kernel.
  
  
  
  Clear Message Pool:
  
  If the message pool is full, you may need to clear it. This can sometimes be done by restarting the transaction or the application server, but be cautious as this may affect ongoing processes.
  
  
  
  Check for System Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as newer versions may have optimizations for message handling.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message. There may be known issues or recommended fixes.
  
  
  
  Monitor Message Generation:
  
  Implement monitoring to track the number of messages generated during transactions. This can help identify patterns and allow for proactive management of message volume.
  
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SM21 (System Log) or SLG1 (Application Log) to review logs for additional context on the messages being generated.
  SAP Community: Engaging with the SAP Community forums can provide insights from other users who may have encountered similar issues.
  Documentation: Review SAP documentation related to message handling and error management for best practices.
  
  If the issue persists after trying the above solutions, it may be necessary to engage SAP support for further assistance.
