  SAP Error Message:
  
  VMP_MSG375 Cannot move components with negative quantity in the empty working panel.
  
  Cause:
  This error occurs in the Production Planning (PP) or Process Manufacturing environment when you attempt to move or post components with a negative quantity in a context where the system does not allow it—specifically, when the working panel (the screen or transaction area where you enter component movements) is empty or does not have a valid reference for such a movement.
  In other words, the system prevents you from entering or processing a negative component quantity if there is no existing component entry or context to reduce from. Negative quantities typically represent returns, scrapping, or reversals, and these require a valid base quantity or stock to deduct from.
  
  When does it typically occur?
  
  During component withdrawal or goods issue postings in production orders or process orders.
  When trying to reverse or correct component quantities without a valid original posting.
  When the user tries to enter a negative quantity in a component movement screen that is empty or not properly initialized.
  
  
  Solution:
  
  
  Check the component quantities:
  
  Ensure that you are not trying to move or post a negative quantity for a component that has no existing positive quantity or stock.
  Verify that the component exists in the order or production process and has a positive quantity before attempting to reduce it.
  
  
  
  Correct the entry:
  
  If you intended to post a positive quantity, correct the sign of the quantity.
  If you intended to reverse a previous posting, make sure you select the correct document or reference that allows a negative posting.
  
  
  
  Initialize the working panel properly:
  
  Make sure the working panel or transaction screen is properly populated with the relevant components before entering negative quantities.
  Sometimes, refreshing or reloading the order or component list helps.
  
  
  
  Use the correct transaction or function:
  
  For reversals or scrapping, use the designated SAP transactions or functions that handle negative postings correctly (e.g., goods movement reversal transactions).
  
  
  
  Check configuration:
  
  In some cases, the system configuration or user exit might restrict negative postings. Consult with your SAP PP or MM consultant to verify if any custom validations or user exits are causing this restriction.

  SAP Notes:  
  
  Check SAP Notes related to component postings and negative quantities in production orders.
  
  
  User roles and authorizations:  
  
  Ensure the user has the necessary authorizations to post negative quantities or reversals.
  
  
  Process Manufacturing:  
  
  In process industries, component movements are tightly controlled; negative postings require valid references.
  
  
  
  
  Summary:
  The error VMP_MSG375 indicates an attempt to post a negative component quantity in a context where the system does not allow it, usually because the working panel is empty or lacks a valid component entry. To resolve, verify component quantities, correct the sign of the quantity, ensure proper initialization of the working panel, and use the correct transactions for reversals or scrapping.
