The scheduling granularity for the project is set to start and end all tasks on hour boundaries, but the scheduled start date for this task occurs between hour boundaries.

To resolve this, do one of the following:

  1. Change the scheduling for this task to As Early As Possible, which will allow it to be scheduled when its prerequisites have been completed on %1@
  2. Move the specified date earlier to the previous hour boundary, %2@, or
  3. Move the specified date later to the next hour boundary, %3@, or
  4. Change the project scheduling granularity to Exact Scheduling.
