Below the Receipt FastTab the next one along is the Warehouse Activities FastTab.
You will see two fields on this FastTab, based on activities that are assigned to users as they are served up on the devices to prevent them being assigned to others. The assignment is not permanent and has a timeout value to free the activity for another user after a certain amount of time has passed.
Soft-assignment occurs when the activity is first served up on the device but before any processing has occurred. If you are unsure, an arbitrary value of 20 minutes has been populated in Act. Soft-assignment (Mins) through the default configuration.
Hard-assignment occurs when processing starts against the activity. Even though the activity may still time-out and be freed for another user, a longer time limit may be desired. An arbitrary value of 120 minutes has been populated in the field Act. Hard-assignment (Mins) via the default configuration.
