  Stock Type Issues: The stock may be in a status that does not allow allocation (e.g., blocked stock, quality inspection stock).
  
  
  Batch Management: If batch management is enabled, the specific batch required for allocation may not be available.
  
  
  Reservation Issues: There may be existing reservations that are preventing the allocation of stock.
  
  
  Configuration Issues: Incorrect configuration in the material master or in the MRP settings can lead to allocation problems.
