How To Fix RPUGEN010 - Maintain maximum number of processes for parallel processing only

SAP Error Message - Details

• Message type: E = Error

• Message class: RPUGEN - General Error Messages in Procurement (ISR)

• Message number: 010

• Message text: Maintain maximum number of processes for parallel processing only

What causes this issue?

In the technical controls, you maintained a maximum number of processes
(value entered > 0) without activating parallel processing. The maximum
number of processes is only relevant for parallel processing, and
should not be entered if you do not execute the program using parallel
processing.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Enter a value of 0 (or no value at all) in the field for the maximum
number of processes.
Start the program and activate parallel processing. However, you can
only do this if you execute the program in the background.

• What is the cause and solution for SAP error message RPUGEN010 - Maintain maximum number of processes for parallel processing only ?

  The SAP error message RPUGEN010 typically occurs in the context of parallel processing in SAP systems, particularly when the system has reached the maximum number of processes that can be executed in parallel. This can happen during batch processing or when executing certain reports that utilize parallel processing capabilities.
  Cause:
  The error message indicates that the system has hit the limit for the maximum number of parallel processes that can be executed. This limit is defined in the system settings and can be influenced by various factors, including:
  
  Configuration Settings: The maximum number of parallel processes is defined in the SAP system configuration. If the limit is set too low, it can lead to this error.
  System Resources: The underlying hardware and system resources (CPU, memory) may not be sufficient to handle more parallel processes.
  Job Scheduling: If there are too many jobs scheduled to run in parallel, it can exceed the configured limits.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Increase Maximum Number of Processes:
  
  Go to transaction RZ10 (Profile Parameter Maintenance).
  Look for the parameter rdisp/wp_no_dia (for dialog work processes) or rdisp/wp_no_btc (for background work processes).
  Increase the value of these parameters to allow more parallel processes. Make sure to consider the available system resources before making changes.
  
  
  
  Check and Optimize Job Scheduling:
  
  Review the scheduled jobs in transaction SM37 (Job Monitoring) to see if there are jobs that can be rescheduled or optimized.
  Ensure that jobs that do not need to run in parallel are scheduled accordingly.
  
  
  
  Monitor System Performance:
  
  Use transaction ST03N (Workload Analysis) to monitor system performance and identify bottlenecks.
  Ensure that the system has adequate resources (CPU, memory) to handle the increased number of parallel processes.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  
  
  
  Test Changes:
  
  After making changes, test the system to ensure that the error does not occur again and that performance is acceptable.

  SAP Notes: Always check the SAP Support Portal for any specific notes related to your version of SAP and the error message.
  Documentation: Review SAP documentation on parallel processing and job scheduling for best practices.
  
  By following these steps, you should be able to resolve the RPUGEN010 error and optimize your SAP system's parallel processing capabilities.
