  Blocked Serial Number: The serial number you are trying to use is already marked as blocked in the system. This could be due to various reasons, such as:

  Look for any associated documents or transactions that might be using the serial number.
  
  
  
  Unblock the Serial Number:
  
  If the serial number is blocked due to a quality issue, you may need to resolve the quality inspection or release the block through the appropriate quality management transactions.

  Consult with Your Team: If you are unsure why the serial number is blocked, consult with your inventory management or quality management team. They may have insights into the specific business processes that could be affecting the serial number.
