• What is the cause and solution for SAP error message WT302 - The reorder point must be less than the target stock ?

  Certainly! Here's a detailed explanation for the SAP error message WT302: "The reorder point must be less than the target stock":
  
  Error Message: WT302
  Text: The reorder point must be less than the target stock.
  
  Cause:
  This error occurs during the maintenance or creation of material master data, specifically in the MRP (Material Requirements Planning) parameters, when the system detects that the Reorder Point (ROP) value is greater than or equal to the Target Stock (TS) value.
  
  Reorder Point (ROP): The inventory level at which a new order should be triggered.
  Target Stock (TS): The desired maximum inventory level to be maintained.
  
  The logic behind this is that the reorder point should always be less than the target stock because:
  
  When stock falls to the reorder point, a replenishment order is triggered.
  The replenishment quantity is intended to bring the stock level back up to the target stock.
  If reorder point = target stock, the system cannot calculate a positive replenishment quantity, which leads to inconsistent planning.
  
  
  Solution:
  
  
  Check and Correct the Values:
  
  Go to the material master record (transaction MM02 or MM01).
  Navigate to the MRP 1 or MRP 2 view (depending on your SAP version).
  Locate the fields for Reorder Point and Target Stock.
  Ensure that the Reorder Point is less than the Target Stock.
  
  For example, if Target Stock = 100, Reorder Point should be something like 50 or 80, but not 100 or more.
  
  
  
  
  
  Adjust Planning Parameters:
  
  If the business process requires a reorder point equal to or greater than the target stock, reconsider the planning strategy or reorder logic.
  Possibly use different MRP types or lot-sizing procedures that better fit the inventory policy.
  
  
  
  Save the Material Master:
  
  After correcting the values, save the material master record.
  The error should no longer appear.
  
  
  
  
  Additional Information:
  
  
  This error is common in reorder point planning (MRP type VB or similar).
  
  
  The system uses the formula:
  Replenishment Quantity = Target Stock - Current Stock
  If reorder point = target stock, replenishment quantity can be zero or negative, which is invalid.
  
  
  This check helps maintain logical consistency in inventory planning and avoids planning errors.
  
  
  If you are using SAP S/4HANA, the same logic applies, but the user interface might be different (e.g., Fiori apps).
