• What is the cause and solution for SAP error message /SAPAPO/OPT_DPS_EXP390 - End of optimization horizon ?

  The SAP error message /SAPAPO/OPT_DPS_EXP390 with the description "End of optimization horizon" typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the optimization process reaches the end of the defined planning horizon. This can happen during the execution of a planning run, such as a heuristic or optimization run, where the system is unable to process any further due to the defined limits of the planning horizon.
  Cause:
  
  Planning Horizon Configuration: The planning horizon may be set too short, causing the optimization process to reach its limit before completing the necessary calculations.
  Data Issues: There may be issues with the data being processed, such as missing or incorrect data that prevents the optimization from proceeding.
  Optimization Settings: The settings for the optimization run may not be configured correctly, leading to premature termination of the process.
  Resource Constraints: If the resources or capacities are not defined properly, the optimization may not be able to extend beyond the current horizon.
  
  Solution:
  
  Extend the Planning Horizon: Review and extend the planning horizon settings in the APO system. This can typically be done in the configuration settings for the planning area or the specific planning run.
  Check Data Integrity: Ensure that all necessary master data (e.g., product, location, resource) and transaction data (e.g., demand, supply) are complete and accurate.
  Review Optimization Settings: Check the settings for the optimization run to ensure they are appropriate for the planning scenario. This includes reviewing the heuristics or optimization algorithms being used.
  Monitor Resource Definitions: Ensure that all resources and capacities are defined correctly in the system. This includes checking for any constraints that may limit the optimization process.
  Run a Test Optimization: If possible, run a test optimization with a smaller dataset or a shorter time frame to identify if the issue persists.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/OPTIMIZE or /SAPAPO/DP to access the relevant planning runs and settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Review the SAP APO documentation for best practices on setting up planning horizons and optimization runs.
  Support: If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance.
  
  By addressing the configuration and data integrity issues, you should be able to resolve the /SAPAPO/OPT_DPS_EXP390 error and successfully complete your optimization runs.
