  The SAP error message /SAPAPO/PINV009 indicates that one or more input parameters for a process in SAP Advanced Planning and Optimization (APO) are negative. This error typically arises during planning runs, such as when executing a planning function or during the execution of a planning scenario.
  Cause:
  The error is caused by the presence of negative values in input parameters that are expected to be non-negative. Common scenarios where this might occur include:
  
  Demand or Supply Values: If the input data for demand or supply contains negative values, it can trigger this error.
  Planning Parameters: Certain planning parameters, such as lot sizes, safety stock levels, or other key figures, should not be negative.
  Data Integrity Issues: There may be issues with the data integrity in the master data or transaction data that lead to negative values being processed.
  
  Solution:
  To resolve the error, follow these steps:
  
  
  Check Input Data: Review the input data for the planning function or scenario that triggered the error. Look for any negative values in key figures or parameters.
  
  
  Data Validation: Ensure that all relevant master data (e.g., material master, location master) and transaction data (e.g., sales orders, purchase orders) are correctly maintained and do not contain negative values where they shouldn't.
  
  
  Adjust Parameters: If the negative values are legitimate (e.g., returns or adjustments), consider adjusting the planning parameters or logic to handle such cases appropriately.
  
  
  Run Data Consistency Checks: Use SAP tools to run consistency checks on your data. This can help identify and correct any discrepancies in the data.
  
  
  Consult Documentation: Review the SAP documentation for the specific planning function or scenario you are using to understand the expected input parameters and their constraints.
  
  
  Debugging: If the issue persists, consider debugging the planning function to identify where the negative values are being introduced.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling negative input parameters.
  Transaction Codes: Familiarize yourself with transaction codes related to APO planning, such as /SAPAPO/MC90 for planning book maintenance or /SAPAPO/DP for demand planning.
