Unable to set completion % in MPP

Hi Abhishek,

As mentioned earlier to you, TASKSNET-1796 will take a little long as the issue with CalculationMode.Manual is of complex nature. We’ve already mentioned your comments to our Product team for consideration. We’ll update you here as soon as there is some information or a fix version available in this regard.

Hi kashif,

Gentle reminder.,!!

Hi Abhishek,

The issue has been fixed for CalculationMode.None. But as mentioned earlier, the CalculationMode.Manual is still having issues and fixes for this mode will start after Aspose.Tasks for .NET 17.7.0 due to the complexities involved. We recommend you to use CalculationMode.None + Project.Recalculate until the issues with Manual mode are resolved. We appreciate your understanding in this regard.

The issues you have found earlier (filed as TASKSNET-1796) have been fixed in this update.

Hi Team,

We have tested your provided ASPOSE Task New release. But still we are facing issue to set % Calculation Value in Tasks using Manual Mode of calculation. Always it is showing 0% for all tasks. We are using below line of code to set % Calculation during writing MPP.

project.CalculationMode = CalculationMode.Manual;
task.Set(Tsk.PercentComplete, Convert.ToInt32(taskItem.CompletionPct));

And also we observed in your latest release that writing to MPP is taking 10 times longer than previous release.

Hi Abhishek,

Thank you for contacting Aspose support team again.

In the current release we have fixed the problems with Duration, Percent complete, Actual duration and Finish in summary tasks when calculation mode None is used. The issue with the calculation mode “Manual” is pending and will be started after release of Aspose.Tasks for .NET 17.7.0 as mentioned in my previous response here. You may please try using Calculation mode None in the meanwhile and share the feedback with us.

I have shared the comments regarding the performance issue with the product team.


When you are releasing .NET 17.7.0 Version with fix for calculation mode manual.
Please tell me the date.

Hi Abhishek,

It is planned to be released at the end of July 2017. We’ll notify you here once the fix version is available for download.
