• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR231 - Value for max_arc_length is smaller than for max_arc_alert_length ?

  The SAP error message /SAPAPO/OM_ERROR231 indicates that there is a configuration issue in the Advanced Planning and Optimization (APO) module, specifically related to the settings for arc lengths in the optimization process. The error states that the value for max_arc_length is smaller than the value for max_arc_alert_length, which is not a valid configuration.
  Cause:
  
  Configuration Mismatch: The error arises when the maximum arc length (max_arc_length) is set to a value that is less than the maximum arc alert length (max_arc_alert_length). This is logically inconsistent because the alert length should not exceed the maximum length allowed for arcs.
  User Input Error: It may also occur due to incorrect manual input during the configuration of the APO settings.
  
  Solution:
  To resolve this error, you need to adjust the configuration settings in the APO system:
  
  
  Access the Configuration:
  
  Go to the transaction code SPRO in the SAP GUI.
  Navigate to the relevant section for APO configuration, typically under SAP Advanced Planning and Optimization > Global Settings > Settings for the Optimization.
  
  
  
  Check and Adjust Values:
  
  Locate the settings for max_arc_length and max_arc_alert_length.
  Ensure that the value for max_arc_length is greater than or equal to the value for max_arc_alert_length.
  If necessary, increase the value of max_arc_length to be greater than max_arc_alert_length.
  
  
  
  Save Changes: After making the necessary adjustments, save the configuration.
  
  
  Test the Configuration: Run the optimization process again to ensure that the error has been resolved.
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or the specific APO documentation for detailed information on configuration settings and their implications.
