Introduction

Relations between work packages are used to give a timely relation to the work packages
- Follows or proceeds, blocked by, part of, etc.
Hierarcies indicate any functional or timely relation:
- Parent-Child relation

Work package relations

Work package relations indicate that work packages address a similar topic or create status dependencies.
To create a relationship between two work packages:

Select a work package, click on Relations to open the relations tab and click the + Create new relations link.
Select the type of relationship from the dropdown menu.
Enter the ID or name of the work package, to which the relation should be created and choose an entry from the dropdown menu.

Relations between Work Packages are useful to establish a time schedule for every task

You can select one of the following relations:
- Related to – This option adds a link from the work package A to work package B, so that project members can immediately see the connection, even if the work packages are not members of the same hierarchy. There is no additional effect.
- Duplicates / Duplicated by – This option indicates that the work package A duplicates a work package B in one way or another, for example both address the same task. This can be useful if you have the same work package that needs to be a part of a closed and public projects at the same time. The connection in this case is semantic, the changes you make in work package A will need to be adapted in work package B manually.
- Blocks / Blocked by – This option defines status change restrictions between two work packages. If you set a work package A to be blocking work package B, the status of work package B cannot be set to closed or resolved until the work package A is closed (in a clode meta-status).
- Precedes / Follows – Defines a chronologically relation between two work packages. For example, if you set a work package A to precede a work package B, you will not be able to change the starting date of B to be earlier than the end date of A. In addition, when you move the start or due date of A, the start and due date of B will be updated as well.
- Includes / Part of – Defines if work package A includes or is part of work package B. This relation type can be used for example when you have a rollout work package and work packages which should be shown as included without using hierarchical relationships. There is no additional effect.
- Requires / Required by – Defines if work package A requires or is required by work package B. There is no additional effect.

Work package hierarchies

Work packages can be structured hierarchically, e.g. in order to break down a large work package into several smaller tasks.
- This means that there’s a parent work package that has at least one child work package.

Adding a Child work package

Open a work package and select the tab Relations.
Click on + Create new child to create a child work package.
1. Alternatively, you can assign an existing child work package with + Add existing child.

Here you can create a new package as a child or assign an existing package as the current package's child

Insert the name of the new work package and save the newly created work package by pressing Enter.

Change the parent work package

To edit or remove the parent of a work package open the work package.
At the top of the details view of the work package you will see the work package hierarchy.
Click on the Edit or delete icon to change the work package parent.

In any work package you can set a new parent or delete the current relation in this field
