Task Group

Task Group Properties

taskgroup_id:
The taskgroup_id is the unique identifier for each task group.

shipment:
A shipment is a collection of task groups that are normally picked together.

The shipment is a numerical value that identifies a shipment. Task groups with an equal shipment property
belong to the same shipment.

The shipment property is a single value; therefore a task group cannot belong to multiple shipments.

A task group is not required to belong to a shipment.

category:
The category property restricts the picking of a task group to Ports which are allowed to pick tasks from a
given category.

A task group must belong to one single category.

req_time:
The req_time is the requested time of the task group, and is used to prioritize different task groups.

It is not logically connected to the current system time, but is a value that is used for sorting (together with the
property priority).

Whether a task group can be started or finished to be picked at a Port until req_time, depends on the available
system resources and the operational situation (e.g. composition and status of the task queue).

priority:
The task groups are prioritized by their requested time and priority. Task groups with earliest requested time
have the highest priority. Task groups with equal requested time are ordered by their priority (lowest value
first; priority 1 before priority 2).

AutoStore does not follow this priority order strictly. AutoStore may deliver lower prioritized tasks in order to
achieve a higher throughput

start_time:
If the start_time property is set, the task group will not be selected by AutoStore until the specified start time is
reached.

The start_time property is optional; by default task groups can be selected by AutoStore immediately after they
are created.

suspended:
A task group that is suspended will not be selected by AutoStore.

The suspended property can be set by the closeport method if the WMS closes the port while the task group is
selected.

The suspended property is cleared when the WMS explicitly selects the task group.
