Differences between Project XML and MPP files
I am using Project Standard 2016 (Version 1908 Build 11929.20300) I have experienced an issue where I am getting differences in data between an original *.mpp file, and an *.xml that I exported from that mpp file. The differences then continue to occur if I then save the first XML file as an XML file again. I have attached the 3 Project files in the .Zip file. These are my steps: Opened the "Sample.MPP", and took a screenshot of the first 23 tasks Saved the file as "Sample.XML". Opened that "Sample.XML" file, selecting 'Import as New Project' when prompted. Took a screenshot of the same Tasks. Saved that as a second XML file "Sample_2".XML (no changes were made to it). Opened that "Sample_2".XML file, selecting 'Import as New Project' when prompted. Took a screenshot of the same Tasks. I compared the screenshots between all 3 files, and noticed that Dates and Durations were continuously changing from the original MPP file (see attached file Differences.png) I checked the Calendar Options and Working Time settings after each file is opened, and they seem all the same: https://www.screencast.com/t/7RdF3B0BdW I also check what the Calendar Options were for 'New Projects' and they were slightly different: https://www.screencast.com/t/3DOPdG9y What is causing these differences? Does the XML Export have certain limitations / not support certain settings? Is there something else that is adjusting the dates when the XML file is being opened/imported as a new Project? Updates: I also tested in MS Project 2019, and the issue still happens. I think it may be related to the fact that the project is using the '24 Hour' calendar. I had another 2 Project files which were exporting / loading XMLs fine, but as soon as i changed the calendar in the MPP files to use "24 Hour", and then exported the XML, once that XML was opened in Project again, the dates/times changed.5.3KViews0likes2Comments
