• What is the cause and solution for SAP error message /SAPAPO/OUTLDET109 - Event to be created would start earlier than history horizon ?

  The SAP error message /SAPAPO/OUTLDET109 indicates that an event you are trying to create in the SAP Advanced Planning and Optimization (APO) system is scheduled to start earlier than the defined history horizon. This typically occurs in the context of planning and forecasting, where the system has a defined period for historical data that it uses to make predictions or plan future events.
  Cause:
  
  History Horizon Configuration: The history horizon is a time frame set in the system that defines how far back the system can look for historical data. If you attempt to create an event that starts before this horizon, the system will throw this error.
  Event Scheduling: The event you are trying to create may have been scheduled incorrectly, leading to a start time that is outside the permissible range defined by the history horizon.
  
  Solution:
  
  
  Adjust the History Horizon:
  
  You can extend the history horizon in the configuration settings of your APO system. This can be done in the relevant planning area settings.
  Navigate to the configuration settings for the planning area and adjust the history horizon to include the time frame of the event you are trying to create.
  
  
  
  Modify Event Timing:
  
  Review the timing of the event you are trying to create. If possible, adjust the start time of the event to fall within the defined history horizon.
  
  
  
  Check Planning Area Settings:
  
  Ensure that the planning area settings are correctly configured to reflect the desired history horizon. This includes checking the settings for the relevant key figures and planning versions.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific instructions on how to adjust the history horizon and other related settings.
