Operation dependencies

This table defines relations between operations. This is used to represent the following situations:

Define which steps in a routing operation can be executed in parallel.

By default routing steps are executed in sequence.

You use the dependencies to configure a non-sequential order of the steps.
Define relations between different steps in a project-oriented business.

In most manufacturing oriented business, a bill-of-material is used to define different levels in the product structure.

As an alternative for project-oriented businesses, this table allows you to directly link subprojects and tasks with each other, without defining intermediate items.

Field	Type	Description
operation	operation	Operation.
blockedby	operation	This operation needs to be completed before the other operation can start.
quantity	double	Defines the quantity relation between both operations. Default value is 1, i.e. the quantity of both operations is identical.
safety_leadtime	duration	Defines a desired time gap between both operations. This time gap is a soft constraint. It can be compressed to deliver an order faster. Default is 0 seconds.
hard_safety_leadtime	duration	Shortest time that must pass between both operations. This time gap is a hard constraint. Default is 0 seconds.
