HI Sir,

My requirement is to modify the timephased data value for any resource assignment. and finally save the entire project in different MPP file.
Please find the below code:

string licenseFileName = Path.Combine(dataDir, “Aspose.Total.Product.Family.lic”);
License license = new License();
license.SetLicense(licenseFileName);

Project project = new Project(“GM_VCU_1_5_rough_top_down_1201060_Read.mpp”) { CalculationMode = CalculationMode.None };

Task tsk1 = project.SelectAllChildTasks().FirstOrDefault(t => t.Get(Tsk.Name) == “Hours - Project management”);
foreach (ResourceAssignment assignment in tsk1.Assignments)
{
// Read timephased data
List td = assignment.GetTimephasedData(assignment.Get(Asn.Start), assignment.Get(Asn.Finish), TimephasedDataType.AssignmentRemainingWork).ToList();

foreach (TimephasedData timePhasedValue in td)
{
timePhasedValue.Value = “PT8H0M0S”;
}
}

project.Recalculate();
project.Save(“AfterLinking_out.mpp”, Aspose.Tasks.Saving.SaveFileFormat.MPP);

after debugging i found that in project variable value is updating but not reflecting into output MPP file.

Hello @chetanbhola.

In order to modify values of TimephasedData you should modify items in ResourceAssignment.TimephasedData collection directly in the following way:

            Project project = new Project("GM_VCU_1_5_rough_top_down_1201060_Read.mpp") { CalculationMode = CalculationMode.None };

            Task tsk1 = project.SelectAllChildTasks().FirstOrDefault(t => t.Get(Tsk.Name) == "Hours - Project management");
            foreach (ResourceAssignment assignment in tsk1.Assignments)
            {
                foreach (TimephasedData timePhasedValue in assignment.TimephasedData)
                {
                    if (timePhasedValue.Value == "PT0H0MS")
                    {
                        continue;
                    }

                    timePhasedValue.Value = "PT8H0M0S";
                }
            }

            project.Recalculate();
            project.Save("AfterLinking_out.mpp", Aspose.Tasks.Saving.SaveFileFormat.MPP);

Also please ensure that you use Aspose.Tasks for .NET v. 21.10 because we released fixes for some issues related to TimephasedData handling.

Hello @chetanbhola.
We examined the attached file and found out that “AfterLinking_out.mpp” is saved by Aspose.Tasks for .NET v 21.6.
Could you check that you use version 21.10 ?
