  Error Message
  WRMA124: Allow negative stock for article &1 in branch &2
  
  &1 = Article number (material number)
  &2 = Branch (plant or storage location)
  
  
  Cause
  This message typically occurs when a transaction (such as goods issue, sales order delivery, or production posting) tries to reduce the stock of a material below zero in a specific branch (plant/storage location), but the system is configured not to allow negative stock for that material in that branch.
  In other words, the system is preventing the stock quantity from going negative because the material master or branch settings do not permit negative stock balances.
  
  Explanation
  
  SAP allows configuration to control whether negative stock is permitted or not.
  Negative stock means the system allows stock quantity to go below zero, which can be useful in some business scenarios (e.g., backorders, just-in-time production).
  If negative stock is not allowed, the system will block transactions that would cause stock to go negative and issue this message.
  
  
  Solution
  
  
  Check Material Master Settings:
  
  Go to transaction MM02 (Change Material).
  Navigate to the Plant Data / Storage 1 view.
  Check the field "Allow Negative Stock" (or similar, depending on SAP version).
  If negative stock is not allowed and business requires it, set this flag to allow negative stock.
  
  
  
  Check Branch/Plant Settings:
  
  Sometimes, negative stock control is also influenced by plant or storage location settings.
  Verify if the plant or storage location allows negative stock.
  
  
  
  Adjust Inventory Management Settings:
  
  In some SAP systems, negative stock control can be set globally or per material.
  Check configuration in SPRO under:
  
  Logistics Execution ? Inventory Management ? Settings for Inventory Management and Physical Inventory ? Define Negative Stock Management.
  
  
  Adjust settings if necessary.
  
  
  
  Review Business Process:
  
  If negative stock is not desired, then ensure that stock is replenished before issuing goods.
  Investigate why stock is insufficient and correct inventory or procurement processes.
  
  
  
  Temporary Workaround:
  
  If urgent, allow negative stock temporarily for the material in the branch.
  Monitor and correct stock levels afterward.

  Negative stock is often used in scenarios like consignment, subcontracting, or backorder processing.
  Always align with business policies before enabling negative stock.
