• What is the cause and solution for SAP error message RZ394 - Sum of work processes changed; values from profile used ?

  The SAP error message RZ394 indicates that the sum of work processes has changed, and the values from the profile are being used. This message typically arises in the context of SAP system configuration, particularly when there are discrepancies between the configuration settings in the instance profile and the actual number of work processes that the system is trying to use.
  Cause:
  
  Profile Changes: The instance profile may have been modified, and the changes have not been properly reflected in the running instance.
  System Restart: If the SAP system was restarted, it may not have picked up the latest configuration settings from the profile.
  Manual Configuration: Manual changes to the number of work processes in the SAP GUI or through transaction codes (like RZ10) may not match the values defined in the profile.
  Parameter Conflicts: There may be conflicting parameters set in the instance profile that affect the number of work processes.
  
  Solution:
  
  
  Check Profile Settings:
  
  Use transaction code RZ10 to check the instance profile settings.
  Ensure that the parameters related to work processes (like rdisp/wp_no_dia, rdisp/wp_no_btc, etc.) are correctly set.
  
  
  
  Restart the Instance:
  
  If changes were made to the profile, restart the SAP instance to ensure that the new settings are applied.
  
  
  
  Consistency Check:

  Compare the values in the profile with the values currently being used by the system.
  
  
  
  Adjust Work Process Configuration:
  
  If necessary, adjust the number of work processes in the profile to match the requirements of your system and restart the instance.
