Error: Multiple schedules with the same data date.

When uploading schedules to SmartPM you cannot have multiple schedules with the same data date.

The options with this error message are to delete the schedules with the same data date that are not needed (if the reason for multiple schedules is quick revisions where you only need the last one) or you can modifying the data date by one day in notepad in order to compare both files in the project.
