• What is the cause and solution for SAP error message /SAPAPO/RSP01146 - Start index (time stamp) is larger than planning horizon (error no. &1) ?

  The SAP error message /SAPAPO/RSP01146 Start index (time stamp) is larger than planning horizon (error no. &1) typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a planning operation is attempted with a start index that exceeds the defined planning horizon. This can happen during various planning activities, such as running a planning job, executing a heuristic, or performing a planning run.
  Cause:
  
  Planning Horizon Configuration: The planning horizon is defined in the APO system and specifies the time frame for which planning is to be executed. If the start index (timestamp) for the planning operation is set beyond this horizon, the system will throw this error.
  Incorrect Time Settings: The time settings in the planning run or job may be incorrectly configured, leading to a start index that is not valid.
  Data Issues: There may be issues with the data being processed, such as incorrect timestamps or missing data that could affect the planning run.
  
  Solution:
  
  
  Check Planning Horizon Settings:
  
  Go to the APO system and check the planning horizon settings for the relevant planning area. Ensure that the planning horizon is set correctly and encompasses the time frame you are trying to plan for.
  You can find these settings in the configuration of the planning area or in the relevant planning book.
  
  
  
  Adjust Start Index:
  
  Review the parameters of the planning job or heuristic you are executing. Ensure that the start index (timestamp) is within the defined planning horizon.
  If necessary, adjust the start index to a valid timestamp that falls within the planning horizon.
  
  
  
  Review Time Settings:
  
  Check the time settings in the planning run or job. Ensure that the start and end dates are correctly defined and that they align with the planning horizon.
  
  
  
  Data Validation:
  
  Validate the data being used in the planning run. Ensure that there are no missing or incorrect timestamps that could lead to this error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific details on configuring planning horizons and handling planning runs.
