• What is the cause and solution for SAP error message /SAPAPO/MAT807 - Negative stockout costs for product &1, location &2, version &3 ignored ?

  The SAP error message /SAPAPO/MAT807 indicates that there are negative stockout costs for a specific product, location, and version in the Advanced Planning and Optimization (APO) module. This message typically arises in the context of supply chain planning, particularly when dealing with stockout costs in the planning process.
  Cause:
  
  
  Negative Stockout Costs: The primary cause of this error is that the stockout costs for the specified product and location are set to a negative value. Stockout costs are intended to represent the cost incurred when a product is out of stock, and having a negative value does not make logical sense in the context of planning.
  
  
  Configuration Issues: This can also occur due to incorrect configuration in the APO system, where the cost settings for the product or location have not been properly defined.
  
  
  Data Entry Errors: There may be data entry errors in the master data or planning data that lead to the assignment of negative values.
  
  
  Solution:
  
  
  Check and Correct Stockout Costs:
  
  Navigate to the relevant product master data in APO.
  Check the stockout cost settings for the product at the specified location and version.
  Ensure that the stockout costs are set to a non-negative value. If they are negative, update them to a reasonable positive value.
  
  
  
  Review Configuration:
  
  Review the configuration settings in the APO system related to cost calculations.
  Ensure that all relevant settings are correctly defined and that there are no inconsistencies.
  
  
  
  Data Validation:
  
  Validate the data entries for the product and location in the master data.
  Look for any anomalies or incorrect entries that could lead to negative stockout costs.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on how to set up stockout costs correctly.
  
  
  
  Testing:
  
  After making changes, run a test planning run to ensure that the error message no longer appears and that the planning results are as expected.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/MAT1 (for product master data) or /SAPAPO/MC62 (for planning book settings) to access and modify the relevant data.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on stockout cost configuration.
  APO Documentation: Review the APO documentation for best practices on managing stockout costs and other related parameters.
  
  By addressing the root cause of the negative stockout costs and ensuring proper configuration and data integrity, you should be able to resolve the error message and proceed with your planning activities in SAP APO.
