• What is the cause and solution for SAP error message /SAPAPO/RSP_OM146 - Start index (time stamp) is larger than planning horizon (error no. &1) ?

  The SAP error message /SAPAPO/RSP_OM146 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 in various scenarios, such as during the execution of a planning run, when trying to access data, or when generating reports.
  Cause:
  
  Planning Horizon Configuration: The planning horizon is defined in the system settings, and it specifies the time frame for which planning data is available. If the start index (timestamp) you are trying to use for a planning operation is beyond this horizon, the system will throw this error.
  Incorrect Time Settings: The time settings in the planning run or the parameters being used may not align with the defined planning horizon.
  Data Availability: There may be a lack of data for the specified time period, leading to the start index being out of range.
  
  Solution:
  
  
  Check Planning Horizon Settings:
  
  Go to the configuration settings for the planning area in SAP APO.
  Verify the planning horizon settings to ensure they are correctly defined and that the start index you are using falls within this range.
  
  
  
  Adjust Start Index:
  
  If you are manually specifying a start index, ensure that it is set to a value that is within the defined planning horizon.
  If the start index is being generated dynamically, review the logic or parameters that determine this value.
  
  
  
  Review Time Settings:
  
  Check the time settings in the planning run or the transaction you are executing. Ensure that the dates and times are correctly set and do not exceed the planning horizon.
  
  
  
  Data Availability:
  
  Ensure that there is sufficient data available for the time period you are trying to access. If necessary, extend the planning horizon or adjust the data accordingly.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific planning area or transaction you are working with for any additional guidance or known issues.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/OM17 (for planning area settings) or /SAPAPO/MC90 (for checking data) to investigate further.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  Support: If the issue persists after checking the above points, consider reaching out to SAP support or your internal SAP team for further assistance.
