User Summary (PD_USER)
Function
The User Summary (PD_USER) record stores the performance data in which the data stored in the Process Detail (PD) record is summarized as the state for each user at a given point in time. A record is created for each user ID. This is a multi-instance record. Note that even if the Process Detail (PD) record is not collected, performance data is stored in the User Summary (PD_USER) record.
