  Cause:
  
  
  Negative Stockout Costs: The primary cause of this error is that the stockout costs for a product have been defined as a negative value in the system. Stockout costs are intended to represent the cost incurred when there is a stockout situation (i.e., when demand cannot be met due to insufficient inventory).
  
  
  Configuration Issues: There may be issues in the configuration of the product master data or the planning book settings that lead to the assignment of negative values.
  
  
  Data Entry Errors: Manual data entry errors during the setup of product master data or planning parameters can also lead to this issue.
  
  
  Solution:
  
  
  Check Product Master Data: 
  
  Go to the product master data in APO and check the stockout cost settings. Ensure that the stockout costs are set to a non-negative value.
  You can access the product master data through transaction /SAPAPO/MAT1 or similar transactions depending on your version.
  
  
  
  Review Planning Parameters: 
  
  Check the planning parameters for the relevant planning book. Ensure that all cost-related parameters are correctly configured and do not contain negative values.
  
  
  
  Correct Data Entry: 
  
  If the negative stockout costs were entered manually, correct the values to reflect the appropriate costs.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help resources for guidance on how to properly configure stockout costs and related parameters.
  
  
  
  Testing: 
  
  After making the necessary changes, run a test planning run to ensure that the error does not reoccur.
  
  
  
  Transport Changes: 
  
  If changes were made in a development environment, ensure that they are transported to the production environment following your organization's change management procedures.
  
  
  
  Related Information:
