The locations in the packaging area are assigned to WLG 01CT, currently assigned to UserA. To ensure UserA receives the transfer task when the task is triggered, UserA must be setup to process a transfer task. Use User Task Assignment Maintenance to add the transfer task to the work Queue.

Alternatively, you can change the locations in the packaging area to WLG 01FL using Warehouse Location Maintenance.

You can assign UserB to Work Location Group 01CT using User Work Location Group Maintenance.

Doing one of the alternatives enables UserB to receive the load transfer task from the packaging to shipping areas.
