TimeTable Visio supports importing schedules in the Microsoft Project schema XMLs.
The following is a known list of data that is not included in XML file when exporting from Primavera P6.
- Free Float (known as Free Slack in Project)
- Total Float (known as Total Slack in Project)
How does this affect my TimeTable?
Total Float is used to calculate "Criticality", and therefore when that information is missing, it's defaulted as 0. You'll know that this data wasn't imported when every task in your project has 0 Total Slack (or Float). If you have TimeTable Visio Pro, then there's the option of Highlighting Critical, choosing this option will show all tasks as Critical which will not be accurate.
How can I fix this?
Most issues can be resolved by importing the XML into Microsoft Project and re-exporting to XML.
