Objects within the same Object Class can be replaced with another one inside the Dispatch Window by scanning the equipment and farmerswife finds the non-scanned item that belongs to the same Object Class inside of the Check Out and replaces it.
In the example video you see that the Arri Alexa 115002 was booked, a Dispatch was created for it, but at the moment of scanning the equipment the Arri Alexa 115004 was scanned, which automatically replaced the 115002, also the Booking got adjusted accordingly.
This is only possible because all the Arri Alexas are in one Object Class and the Dispatch Status was set to "In Preparation". Only this Dispatch Status allows the swap equipment.
As soon as equipment is scanned, you can't swap it anymore. You will need to remove the equipment and add the new equipment.
Please note the "In Preparation (No Swapping)" Dispatch Status is used when you need to create a carnet list for the equipment as it goes over the border. You really don't want anyone to swap any equipment. It is possible to set all Dispatches that are created from a Booking to the Dispatch Status: In Preparation (No Swapping) by activating the setting in the Toolbox > Settings tab > Dispatch Module > Set Dispatch Status To "In Preparation (No Swapping)" When creating Dispatch From Booking. This is usually used if you don't want your team to swap any equipment.

In the Booking the Object Class was booked, but no real Object. In the Check Out the Object Class can now be replaced with any member by scanning it.
