• What is the cause and solution for SAP error message PMMO_BASIS023 - Parallel processing dispatcher could not be instantiated: Not authorized ?

  The SAP error message PMMO_BASIS023 indicates that the parallel processing dispatcher could not be instantiated due to authorization issues. This error typically arises in the context of background processing or parallel processing tasks in SAP.
  Cause:
  The primary cause of this error is that the user or the system does not have the necessary authorizations to create or manage parallel processing tasks. This can happen due to:
  
  Missing Authorizations: The user executing the transaction or program does not have the required authorizations in their user profile.
  Profile Issues: The user profile may not include the necessary roles or authorizations related to parallel processing.
  System Configuration: There may be system-wide settings or configurations that restrict parallel processing capabilities.
  
  Solution:
  To resolve the PMMO_BASIS023 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check for missing authorizations.
  Review the authorization objects related to parallel processing, such as S_BC (Background Processing) and S_TCODE (Transaction Codes).
  
  
  
  Adjust User Roles:
  
  If you identify missing authorizations, work with your SAP security team to adjust the user roles and profiles to include the necessary permissions for parallel processing.
  
  
  
  Review System Settings:
  
  Check the system configuration for any restrictions on parallel processing. This may involve reviewing system parameters or settings in transaction RZ10 or RZ11.
  
  
  
  Test with a Different User:
  
  If possible, try executing the same process with a different user account that has the necessary authorizations to determine if the issue is user-specific.
