  The SAP error message KV159 ("Reporting point/operation &: WIP cannot be negative") typically occurs in the context of production order processing, particularly when dealing with Work in Progress (WIP) calculations. This error indicates that the system has detected a situation where the WIP amount for a particular operation or reporting point is being calculated as negative, which is not permissible.
  Causes:
  
  Incorrect Data Entry: There may be incorrect or incomplete data entered in the production order, such as negative quantities or incorrect reporting of completed operations.
  Order Status: The production order might be in a status that does not allow for further processing, such as being closed or technically completed.
  WIP Calculation Issues: The WIP calculation logic may be flawed due to incorrect settings or configurations in the system.
  Material Movements: There may have been material movements (goods issues or receipts) that were not properly accounted for, leading to discrepancies in the WIP calculation.
  Incorrectly Defined Operations: The operations defined in the routing may not align with the actual production process, leading to incorrect WIP calculations.
  
  Solutions:
  
  Check Production Order Data: Review the production order for any incorrect entries, especially in terms of quantities and statuses. Ensure that all operations are correctly reported.
  Review Order Status: Ensure that the production order is in a valid status for processing. If it is closed or technically completed, you may need to reopen it or adjust the status.
  Adjust WIP Calculation Settings: If the issue persists, review the configuration settings related to WIP calculations in the system. This may involve checking the settings in the controlling area or the relevant production settings.
