What is the Timekeeper ID used for in the Interest Generation Program?

The Timekeeper ID used in the Interest Generation program is solely for purposes of assigning an ID to the interest transactions created.  If you were to enter the interest transactions manually through the Expense Entry Program, this ID would be entered in the ID field.  The ID used in Interest Generation has no effect on which Client-Matters will have interest generated.  In other words, this ID is not a method by which to generate interest for a particular Responsible (Billing) attorney.
