The schedules of types/document-types can be linked together by a parent-child relationship. The parent will start the child when its schedule is started and will finish when all of it's children schedules are finished. The activities of both child and parent can be linked by defining the predecessors for the child/parent activities.

1. Enable AWS for the types/document-types.

2. The Collections/References need to be created the following way
Types.Type.collections
Types.Type.references

3. Update the Administration->Advanced Workflow and Scheduling->Settings
so links is not null but instead an object that has either parents, children or both parents and children, example below

this will allow you to select predecessors from other schedules. It opens an open text field where you write for example

With a reference the activity with the following predecessor with start as soon as the predecessor has finished that activity.
If for example it is a collection instead the activity will not start until all the entities in the collections have finished the particular activity with that activity code
