The scheduling granularity for the project is set to start and end all tasks on hour boundaries, but the locked start date for this task occurs on %1@ between hour boundaries.
To resolve this, do one of the following:
- Unlock this task, which will allow it to be scheduled when its prerequisites have been completed on %2@
- Move the locked date earlier to the previous hour boundary, %3@, or
- Move the locked date later to the next hour boundary, %4@, or
- Change the project scheduling granularity to Exact Scheduling.
