WBS Associated with a Task

WBS codes, work breakdown structure codes, lets you assign outline numbers to tasks according to the needs of your business. It’s a method for applying a customized outline scheme to a project. Aspose.Tasks for Java supports this feature.

Working with Work Breakdown Structure

The WBS and WBSLevel properties exposed by the Tsk class is used to read and write a tasks work breakdown structure:

• WBS: sets or gets a task’s WBS code (string).
• WBS_LEVEL: sets or gets a task’s WBS level (string).

Microsoft Project View of WBS

To view WBS information in Microsoft Project:

1. On the Task Entry Form, select the Insert menu and then Column.
2. Add the WBS column.

Getting WBS in Aspose.Tasks

The following examples show how to get a task’s WBS value using Aspose.Tasks.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(WbsAssociatedWithTask.class);

Project project = new Project(dataDir + "input.mpp");

// Create a ChildTasksCollector instance
ChildTasksCollector collector = new ChildTasksCollector();

// Collect all the tasks from RootTask using TaskUtils
TaskUtils.apply(project.getRootTask(), collector, 0);

// Parse through all the collected tasks
for (Task tsk : collector.getTasks()) {
    System.out.println(tsk.get(Tsk.WBS));
    System.out.println(tsk.get(Tsk.WBS_LEVEL));
    // set custom WBS
    tsk.set(Tsk.WBS, "custom wbs");
}

Renumber WBS Codes

Aspose.Tasks for Java API can renumber WBS codes similar to MSP’s “Renumber” function.

String dataDir = Utils.getDataDir(WbsAssociatedWithTask.class);
        
Project project = new Project(dataDir + "RenumberExample.mpp");

List<Task> tasks = (List<Task>) project.getRootTask().selectAllChildTasks();

System.out.println("WBS codes before: ");

// output: ""; "1"; "2"; "4"
for (Task task: tasks)
{
    System.out.println("\"" + task.get(Tsk.WBS) + "\"" + "; ");
}

// project.RenumberWBSCode(); // this overload could have used too
List<Integer> listIds = new ArrayList<>();
listIds.add(1);
listIds.add(2);
listIds.add(3);
project.renumberWBSCode(listIds);

System.out.println("\nWBS codes after: ");

// output: ""; "1"; "2"; "3"
for (Task task: tasks)
{
    System.out.println("\"" + task.get(Tsk.WBS) + "\"" + "; ");
}
