  Cause:
  
  Existing Reservation: The primary cause of this error is that there is already a reservation in the system for the specified customer (indicated by &1) for the same material or item. SAP does not allow multiple reservations for the same customer and item combination to avoid conflicts in inventory management.
  Data Entry Error: Sometimes, this error can occur due to incorrect data entry, such as trying to create a reservation for a customer that already has a reservation in the system.
  System Configuration: In some cases, the system configuration may enforce strict rules regarding reservations, leading to this error.

  Check Existing Reservations: 
  
  Use transaction codes like MB22 (Change Reservation) or MB23 (Display Reservation) to check if there is an existing reservation for the customer and item in question.

  Create New Reservation: 
  
  After addressing the existing reservation, you can attempt to create a new reservation again using the appropriate transaction (e.g., MB21 for creating a reservation).
  
  
  
  Consult with Colleagues: If you are unsure about the existing reservation's validity, consult with colleagues or the inventory management team to ensure that you are not disrupting any ongoing processes.
