Working With Assignment Variances

Dealing Variances

The Asn class exposes several properties for handling variance in an assignment’s baseline values and the actual cost, start date, finish date 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 code example demonstrates how to get the resource work variance using Aspose.Tasks.

// Create project instance
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"ResourceAssignmentVariance.mpp");
    
// Print assignment variances
    
{
    auto ra_enumerator = (project1->get_ResourceAssignments())->GetEnumerator();
    decltype(ra_enumerator->get_Current()) ra;
    while (ra_enumerator->MoveNext() && (ra = ra_enumerator->get_Current(), true))
    {
        System::Console::WriteLine(System::ObjectExt::Box<Duration>(ra->Get<Duration>(Asn::WorkVariance())));
        System::Console::WriteLine(ra->Get<double>(Asn::CostVariance()));
        System::Console::WriteLine(System::ObjectExt::Box<Duration>(ra->Get<Duration>(Asn::StartVariance())));
        System::Console::WriteLine(System::ObjectExt::Box<Duration>(ra->Get<Duration>(Asn::FinishVariance())));
    }
}
