Dealing Variances

Managing Variances

The ResourceAssignment class exposes several properties for handling variance in an assignment’s baseline values and the actual cost, start date, finish data and work:

• CostVariance handles the variance in cost against an assignment’s baseline (double).
• StartVariance handles the variance in start date against an assignments baseline (integer).
• FinishVariance handles the variance in end date against an assignments baseline (integer).
• WorkVariance handles the variance in work against an assignment’s baseline (double).

To see resource assignment variances in Microsoft Project:

1. On the Task Usage screen, select Insert and ten Columns.
2. Add the desired columns.

Getting Assignment Variance in Aspose.Tasks

The following example shows how to get the resource work variance 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(DealingVariances.class);

Project project = new Project(dataDir + "project5.mpp");

for (ResourceAssignment ra : project.getResourceAssignments()) {
    System.out.println(ra.get(Asn.WORK_VARIANCE));
    System.out.println(ra.get(Asn.COST_VARIANCE));
    System.out.println(ra.get(Asn.START_VARIANCE));
    System.out.println(ra.get(Asn.FINISH_VARIANCE));
}
