View FPSBASE.RTG_REF_QUEUE_TIMER_STEP_PCT
This table has the primary key of timer_id, facility, route, and step and calculates the timer start percentage for each step in the queue timer. It only works for timers which start and end on the same route.

FACILITY |
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. (* inherited from FPSINPUT.GEN_FACILITIES) |
|
TIMER_ID |
Unique number representing the queue timer to index with other tables. Automatically populated with RTG_QUEUE_TIMERS_ID_SEQ sequence. (* inherited from FPSINPUT.RTG_QUEUE_TIMERS) |
|
ROUTE |
Route that has threading requirements (* inherited from FPSINPUT.RTG_STEP_THREADING) |
|
STEP |
A single processing step within a route representing a single tool visit. Step is often a very complex string and should rarely be displayed. Instead we should use process_display. (* inherited from FPSINPUT.RTG_ROUTE_STEPS) |
|
SEQ_NUM |
Sequence number of step in route (* inherited from FPSINPUT.RTG_ROUTE_STEPS) |
|
START_STEP |
Start step that will impact the future thread step rank in RTG_TOOL_ASSIGNMENT_LOT (* inherited from FPSINPUT.RTG_STEP_THREADING) |
|
END_STEP |
The step upon move out where the WIP balance limit is no longer applied (* inherited from FPSINPUT.RTG_STEP_BALANCE) |
|
TIMER_START_EVENT |
The WIP event type which starts the queue timer at the start step. The default and preferred choice is END since most timers should start when the lot ends processing at the start step but other choices are DISPATCH, BEGIN, and COMP. These four choices are a subset of list in WIP_EVENT_TYPES. This column would be more accurately named TIMER_START_EVENT_TYPE but this is in use everywhere and changing ETL makes upgrades significantly more difficult so we are leaving this slightly confusing column name. (* inherited from FPSINPUT.RTG_QUEUE_TIMERS) |
|
TIMER_END_EVENT |
The WIP event type which ends the queue timer at the end step. Prior to Scheduler version 1.18.1, the only choice is BEGIN so all timers will end when the lot starts processing at the end step. For 1.18.1+, DISPATCH, BEGIN, END, and COMP are all available options. Please note that scheduling timers that end on COMP and END events is much more difficult, as many factors can introduce significant variability to the processing time of a lot. DISPATCH and BEGIN are the preferred event types to use here. (* inherited from FPSINPUT.RTG_QUEUE_TIMERS) |
|
EXPIRED_SEC |
Seconds from the start event until queue time restriction is expired. After expiration, the lot must rework or scrap or otherwise be evaluated. (* inherited from FPSINPUT.RTG_QUEUE_TIMERS) |
|
WARN_SEC |
Seconds from the start event until warning limit for queue time restriction. Lots that remain in the timer sequence longer than this warning limit should be prioritized to prevent them from expiring. (* inherited from FPSINPUT.RTG_QUEUE_TIMERS) |
