The scheduling granularity for the project is set to start and end all tasks on day boundaries, but the locked start date for this task occurs on %1@ between day boundaries.

To resolve this, do one of the following:

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