FPSAPP.EQP_MNT_COUNTER_HIST

FACILITY

VARCHAR2(6)

N

Facility is included in almost every join in the DWH so this represents a definitive split. A route must have all steps on tools in the same facility. A tool must process all lots in the same facility. If your site has multiple buildings where lots run on routes using tools in multiple buildings then everything should be one facility. For example, multiple Fab buildings. But if your site has independent facilities like Fab and Test and Assembly where lot may progress from one to the next but on different routes then these should be different facilities. Since this column is in virtually every table it is critical that the value here is exactly matches what is in the MES if the MES has facility. Use facility_display for the display friendly name displayed in applications. See site_name comment for client/site/facility example. (* from FPSINPUT.GEN_FACILITIES)

EVENT_ID

VARCHAR2(64)

N

Field that uniquely identifies the maintenance task definition in the facility. `Event_id` is usually a number or code from the maintenance system, but it could also be defined as `logged_entity` concatenated with `mnt_name`, since that combination also uniquely represents an event. It is important to ensure that our definition of `event_id` represents repeated instances of the same maintenance event with the same `event_id`. For example, if we have a monthly PM on tool T1, there will be instances of this event each month. The field used as `event_id` could be something like T1 monthly PM; it should *not* be something like T1 monthly PM Jan, T1 monthly PM Feb, etc., since this would cause the `event_id` to change every month. (* from FPSINPUT.EQP_MNT_FUTURE)

INST

DATE

N

Time when the event occurred. (* from FPSINPUT.WIP_EVENT_HIST)

COUNTER_VALUE

NUMBER(12,3)

N

Value of the counter at the inst.

INSERTED_TIME

TIMESTAMP(6)

Timestamp field set by trigger storing SYSTIMESTAMP when record was inserted in the table. (* from FPSINPUT.WIP_EVENT_HIST)

OPERATOR

VARCHAR2(64)

In history tables, this is the username of the person or system who logged the event. In EQP_MNT_FUTURE, this is the username of the person who input the information about the maintenance event. Usernames can be looked up in GEN_USERS to get full names, email address, etc. Please note that the existence of each username in GEN_USERS is optional, meaning that it is never required for the username logged in the operator column to be in GEN_USERS.
