• What is the cause and solution for SAP error message /PF1/MSG_GUI255 - Objects not available for parallel processing ?

  The SAP error message /PF1/MSG_GUI255 Objects not available for parallel processing typically occurs when you are trying to execute a process that is not designed to run in parallel. This can happen in various scenarios, such as when using background jobs, parallel processing in reports, or when dealing with certain transactions that do not support parallel execution.
  Cause:
  
  Non-parallelizable Objects: The objects or processes you are trying to execute are not designed to be processed in parallel. This could be due to dependencies between tasks or the nature of the data being processed.
  Configuration Issues: There may be configuration settings in the SAP system that restrict certain processes from being executed in parallel.
  Transaction Limitations: Some transactions or reports inherently do not support parallel processing due to their design.
  
  Solution:
  
  Check Object Compatibility: Review the documentation for the specific transaction or report you are trying to run to determine if it supports parallel processing. If it does not, you will need to run it in a single-threaded mode.
  Adjust Job Settings: If you are using background jobs, check the job settings to ensure that they are configured correctly. You may need to adjust the job to run in a non-parallel mode.
  Review Configuration: Consult with your SAP Basis or system administrator to review any configuration settings that may be affecting parallel processing capabilities.
