How To Fix LUMER003 - Do not simulate more than &1 values due to long response times

SAP Error Message - Details

• Message type: E = Error

• Message class: LUMER - Messages for Quantity Optimizing

• Message number: 003

• Message text: Do not simulate more than &1 values due to long response times

What causes this issue?

There are more than &1 values in the interval you entered for the
increment selected. Simulating more than &1 values would lead to a long
response time.

System Response

INCLUDE ISR_STOP

How to fix this error?

Select an interval with a smaller number of values (a maximum of &1
values) or increase the increment instead.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message LUMER003 - Do not simulate more than &1 values due to long response times ?

  The SAP error message LUMER003 indicates that a simulation process is attempting to handle more values than the system can efficiently process, leading to long response times. This error typically occurs in the context of SAP's logistics or planning modules, where simulations or calculations are performed on large datasets.
  Cause:
  
  Excessive Data Volume: The simulation is trying to process more values than the system is configured to handle efficiently. This can happen if a user selects too many items or parameters for simulation.
  System Performance: The underlying system may not have sufficient resources (CPU, memory) to handle the requested operation in a timely manner.
  Configuration Limits: There may be predefined limits in the system settings that restrict the number of values that can be processed in a single simulation.
  
  Solution:
  
  Reduce the Number of Values: Try to limit the number of items or parameters you are simulating. Break down the simulation into smaller batches to avoid overwhelming the system.
  Optimize the Simulation Parameters: Review the parameters being used in the simulation and see if any can be adjusted to reduce the load.
  Check System Performance: Monitor system performance metrics to identify any bottlenecks. If the system is under heavy load, consider running simulations during off-peak hours.
  Increase System Resources: If feasible, consider upgrading the hardware resources of the SAP system (e.g., adding more memory or CPU power) to better handle larger simulations.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this issue or provide additional configuration options.
  Configuration Adjustments: If you have access to system configuration settings, you may want to review and adjust any limits related to simulation processing.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the specific module you are working with, as it may provide additional insights into simulation limits and performance tuning.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found effective.
  Performance Monitoring Tools: Utilize SAP's performance monitoring tools (like ST03N, ST04) to analyze system performance and identify potential issues during simulation runs.
  
  By following these steps, you should be able to mitigate the LUMER003 error and improve the performance of your simulations in SAP.
