• What is the cause and solution for SAP error message WT303 - The minimum target stock must not be greater than the max. target stock ?

  SAP Error Message:
  
  WT303 – The minimum target stock must not be greater than the max. target stock
  
  Cause:
  This error occurs when the system detects that the Minimum Target Stock value is set higher than the Maximum Target Stock value in the material master or planning parameters. In SAP, the minimum target stock should logically be less than or equal to the maximum target stock to maintain consistent inventory planning and control.
  
  Where it typically occurs:
  
  In Material Master data under MRP 2 view (fields related to planning)
  When setting up Planning Parameters for materials (e.g., reorder point planning, forecast-based planning)
  During MRP run or when maintaining planning data manually
  
  
  Explanation:
  
  Minimum Target Stock: The minimum quantity of stock you want to have available.
  Maximum Target Stock: The maximum quantity of stock you want to hold.
  
  If the minimum is greater than the maximum, it contradicts the logic of inventory control and planning, hence SAP throws this error to prevent inconsistent data.
  
  Solution:
  
  
  Check and Correct the Values:
  
  Go to the material master (transaction MM02).
  Navigate to the MRP 2 view.
  Verify the values for:
  
  Minimum Target Stock (field: Minimum stock level or similar depending on configuration)
  Maximum Target Stock (field: Maximum stock level or similar)
  
  
  Ensure that the minimum target stock is less than or equal to the maximum target stock.
  
  
  
  Adjust Planning Parameters:
  
  If the values are maintained via planning parameters or custom settings, review and correct them accordingly.
  
  
  
  Save the changes and re-run the MRP or the process that triggered the error.
  
  
  
  Additional Information:
  
  This error helps maintain logical consistency in inventory management.
  If you are unsure about the correct values, consult your inventory planning or production planning team.
  Sometimes, this error can also appear if the fields are accidentally swapped or incorrectly entered during data upload or mass maintenance.
  In some cases, the error might appear during batch input or LSMW if the data file has incorrect values.
