• What is the cause and solution for SAP error message RSCRT149 - Value '00' is not allowed as daemon; values '01' to '99' only ?

  The SAP error message RSCRT149 indicates that a value of '00' has been assigned to a daemon, which is not permitted. In SAP, daemons are typically used in the context of background processing, and they require a valid identifier in the range of '01' to '99'. The value '00' is not a valid identifier for a daemon.
  Cause:
  The error occurs when:
  
  A configuration or setting in the SAP system has been incorrectly set to '00' for a daemon.
  This could be due to manual input errors, incorrect configuration during system setup, or issues in a custom program that sets daemon values.
  
  Solution:
  To resolve the RSCRT149 error, follow these steps:
  
  
  Identify the Source of the Error:
  
  Check the configuration settings related to background processing or daemon settings in your SAP system.
  Look for any custom programs or scripts that might be setting the daemon value incorrectly.
  
  
  
  Correct the Daemon Value:
  
  Change the daemon value from '00' to a valid value within the range of '01' to '99'.
  This can typically be done in the relevant configuration transaction (e.g., SM37 for job monitoring, or other relevant transactions depending on your setup).
  
  
  
  Review Background Job Settings:
  
  If the error is related to a specific background job, review the job settings to ensure that all parameters are correctly configured.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the background job or process that was causing the error to ensure that it runs successfully without generating the RSCRT149 error.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct daemon values or how to configure them, refer to the SAP documentation or consult with your SAP Basis team.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Background Processing: Familiarize yourself with how background processing works in SAP, including the role of daemons and job scheduling.
  Transaction Codes: Common transaction codes related to background processing include:
  
  SM37: Monitor background jobs
  SM36: Define background job
