• What is the cause and solution for SAP error message /SAPAPO/PE078 - Parallel processing active. Enter the max. number of parallel processes ?

  The SAP error message /SAPAPO/PE078 Parallel processing active. Enter the max. number of parallel processes typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to execute a process that is configured to run in parallel, but the system requires a specification of the maximum number of parallel processes to be used.
  Cause:
  
  Parallel Processing Configuration: The system is set up to allow parallel processing for certain tasks, but the maximum number of parallel processes has not been defined.
  User Input: The user may have initiated a process that requires parallel execution without specifying the number of processes.
  System Settings: The system settings or user profile may not have a default value for the maximum number of parallel processes.
  
  Solution:
  To resolve this error, you need to specify the maximum number of parallel processes when prompted. Here are the steps to do this:
  
  Identify the Process: Determine which process you are trying to execute that is causing the error.
  Specify Max Parallel Processes:
  
  When prompted by the error message, enter a valid number for the maximum parallel processes. This number should be based on your system's capacity and the nature of the task.
  A common practice is to start with a lower number (e.g., 2 or 4) and increase it based on performance and system load.
  
  
  Check User Settings: If you frequently encounter this error, consider checking your user profile settings or system configuration to set a default value for the maximum number of parallel processes.
  Consult Documentation: Refer to SAP documentation or your system administrator for guidelines on optimal settings for parallel processing based on your specific environment and workload.
  
  Related Information:
  
  Performance Considerations: While parallel processing can improve performance, setting the number too high can lead to resource contention and degrade overall system performance. Monitor system performance and adjust as necessary.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  Transaction Codes: Familiarize yourself with transaction codes related to APO and parallel processing, such as /SAPAPO/DP for demand planning or /SAPAPO/SC for supply chain planning, as they may provide additional context for the error.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or APO support team for further assistance.
