Hi Bill,
Enter "fields" into the ask a question box in Project. You will see
categories for Resource Fields, Task Fields, Assignment Fields,
Resource-timephased fields, Task-timephase fields, and Assignment-timephase
fields.
For help on a specific field you see in a table, hover over the column
(field) title and click the hyperlink to go directly to help on that specific
field.
Hope this helps. Let us know how you get along.
Julie
