• What is the cause and solution for SAP error message RPUGEN008 - Parallel processing only possible if program is run in background ?

  The SAP error message RPUGEN008 indicates that parallel processing is only possible when the program is executed in the background. This error typically arises when a report or program that is designed to run in parallel processing mode is executed in the foreground instead.
  Cause:
  The primary cause of this error is that the program is attempting to utilize parallel processing features, which require the program to be executed in the background. When running in the foreground, the system does not allow parallel processing due to the way user sessions are managed and the need for user interaction.
