How do I search the schedule for rows (i.e. show only activities a particular resource has been assigned to)?

Filters allow a user to search in a specified column for a value. Based on the defined search criteria, the matching rows will be displayed.

Create a filter to show a specific resource's assignments:
1. While in Schedule View, go to the Project menu
2. Select Filters > Define...
3. Select New...
4. Rename filter, perhaps to the name of the resource
5. Go to Column/Value Criteria tab
6. Under Column, select Resources Assigned (or other column name used)
7. Under Test, select *txt* (Contains)
8. Under Value, enter Resource Name

To see all rows again, click on the Restore All button (red arrow at the bottom left corner of schedule) or from the Project menu, select Filters > Restore All.
