The Enterprise Project Structure (EPS) hierarchy viewer displays summarized data. The "Update Project and Resource Base Summaries" process calculates this data. When the summarization period option is set to 'Annual', the process uses the current system date to determine the calendar year for which to summarize the data. In this scenario, the job running on 15-Dec-2015 uses 2015 as the current year and therefore calculates and displays labor demand for the entire 2015 calendar year, not a rolling 12-month period from the current date.

A. "Current period start date" is vague; the calculation is based on the current calendar year derived from the system date, not an arbitrary period start date.

C. The project start date is irrelevant for calculating the ongoing annual labor demand summary; the current date determines the summarization year.

D. The "Update EPS" summarization job does not typically take a user-entered date as a parameter for the calculation period; it uses the system date.
