Float data in XML export from P6

Hello,

I'm preparing the upgrade of our P6 EPPM with the latest version which seems to allow only XML export.

For this purpose, I'm updating some of our planning Dashboards (automatically done from XER or xls export) but cannot find all required data into the XML export.

Particularly, the Free and Total Floats seem not to be in the list of information available for each activity.

Does anyone already had such difficulties? any workaround is available to have these information directly from the XML file?

Many thanks.
