• What is the cause and solution for SAP error message RZ352 - Total number of work processes is determined from the instance profile ?

  The SAP error message RZ352 indicates that the total number of work processes for an SAP instance is determined from the instance profile. This message typically arises when there is a configuration issue related to the work processes in the SAP system.
  Cause:
  
  Profile Configuration: The number of work processes is defined in the instance profile (usually the DEFAULT.PFL or instance-specific profile). If the profile is not correctly configured or if there are issues with the profile parameters, this error can occur.
  Instance Profile Not Loaded: If the instance profile is not loaded correctly during the startup of the SAP instance, the system may not be able to determine the number of work processes.
  Parameter Settings: The parameters that define the number of work processes (like rdisp/wp_no_dia, rdisp/wp_no_btc, etc.) may not be set correctly or may be missing.
  
  Solution:
  
  
  Check Instance Profile:
  
  Go to the SAP system and check the instance profile settings. You can do this using transaction RZ10.
  Look for parameters related to work processes, such as rdisp/wp_no_dia (for dialog work processes), rdisp/wp_no_btc (for background work processes), etc.
  Ensure that these parameters are set to appropriate values based on your system's requirements.
  
  
  
  Modify Profile:
  
  If the parameters are missing or incorrect, modify the instance profile accordingly.
  After making changes, save the profile and restart the SAP instance for the changes to take effect.
  
  
  
  Check for Errors in the Developer Trace:
  
  Use transaction SM21 to check the system log for any related errors or warnings that might provide more context about the issue.
  You can also check the developer trace files (found in the dev_* files in the work directory of the instance) for any additional error messages.
  
  
  
  Restart the Instance:
  
  After making changes to the profile, restart the SAP instance to ensure that the new settings are applied.
  
  
  
  Consult SAP Notes:
  
  If the issue persists, consult the SAP Support Portal for any relevant SAP Notes that might address this specific error message.
