*Note that the properties listed here only cover the built-in properties of the OpenProject Core.
Using plug-ins and custom fields a work package might contain various additional properties.
A client can consult the schema information to which the work package links. The schema will contain information about
all properties of the linking work package, including properties added by plug-ins and custom fields.*
*Custom fields are identified by a key in the form of `customFieldN`, where `N` is an integer. Depending on their type,
they can occur as properties or as linked properties. A client has to consult the schema to resolve
the human readable name of custom fields.*
*Properties that cannot be set directly on parent work packages are inferred from their children instead:*
* `startDate` is the earliest start date from its children
* `dueDate` is the latest due date from its children
* `estimatedTime` is the sum of estimated times from its children
* `percentageDone` is the weighted average of the sum of its children percentages done. The weight is given by the average of its children estimatedHours. However, if the percentage done is given by a work package's status, then only the status matters and no value is inferred.
*Start date can also not be earlier than a due date of any predecessor.*

+ id (required, integer, `1`) ... User id
+ Response 204
+ Response 403 (application/hal+json)

## Available relation candidates [/api/v3/work_packages/{id}/available_relation_candidates{?filters,query,type,pageSize}]
Lists work packages with which this work package can be in a relation.
Only sound candidates are returned. For instance a work package cannot stand in relation to itself,
and a work package that follows another cannot precede it.
Candidates can be filtered. Most commonly one will want to filter by subject.
You can do this through the `filters` parameter which works just like the work package index.
For instance to find all work packages with "rollout" in their subject:
```
?filters=[{"subject":{"operator":"~","values":["rollout"]}}]
```
For convenience there is also a simple `query` parameter which is a shortcut for listing work packages
whose ID or subject contain the given string.
While the endpoint does support the pageSize parameter to limit the number of results it
**does not** support the offset parameter.
```
?query=112
