• What is the cause and solution for SAP error message /SAPAPO/RSP336 - Order outside the planning horizon. Calendar tree extended to &1 ?

  The SAP error message /SAPAPO/RSP336 Order outside the planning horizon. Calendar tree extended to &1 typically occurs in the SAP Advanced Planning and Optimization (APO) module when an order is scheduled or planned outside the defined planning horizon. This can happen for various reasons, such as changes in demand, supply, or planning parameters.
  Cause:
  
  Planning Horizon Configuration: The planning horizon is defined in the APO system and determines the time frame within which planning activities can occur. If an order is created or modified to a date that falls outside this horizon, the error will be triggered.
  Order Dates: The order may have been created with a delivery date or production date that exceeds the current planning horizon.
  Changes in Demand or Supply: Changes in demand or supply can push orders outside the planning horizon if the planning parameters are not adjusted accordingly.
  Calendar Settings: The calendar settings in the APO system may not align with the order dates, leading to discrepancies.
  
  Solution:
  
  Adjust Planning Horizon: Extend the planning horizon in the APO system to include the order dates. This can be done in the configuration settings for the planning area.
  
  Navigate to the relevant configuration settings in SAP APO and adjust the planning horizon parameters.
  
  
  Review Order Dates: Check the order dates and ensure they are within the defined planning horizon. If necessary, adjust the order dates to fall within the planning horizon.
  Check Calendar Settings: Ensure that the calendar settings in the APO system are correctly configured and aligned with the order dates.
  Re-run Planning: After making the necessary adjustments, re-run the planning process to see if the error persists.
  Consult Documentation: Refer to SAP documentation or help resources for specific instructions on adjusting the planning horizon and understanding the implications of such changes.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/MC90 (for planning area settings) or /SAPAPO/DP90 (for demand planning) to access relevant configuration settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on planning horizon issues.
  User Exits and BAdIs: If custom logic is implemented in your APO system, review any user exits or BAdIs that may affect planning horizon behavior.
  
  By addressing the planning horizon and ensuring that orders are scheduled within the defined timeframe, you should be able to resolve the error message /SAPAPO/RSP336.
