View FPSBASE.RTG_REF_QUEUE_MULTI_AREA_PATH
This checks all steps in the queue timer for each lot which are not skippable metrology to see if they have a run path. If not then we are not allowed to start into the timer. Unlike RTG_QUEUE_MULTI_AREA_WIP there is no intelligent calculation for when we might be able to start into the timer or any ability to trickle lots into the timer. We simply have no path so we cannot start.

LOT |
A lot is a group of units that process together. Usually lot_id or lot_number in MES. All units in a lot are in the same carrier but there may be multiple lots in a carrier. (* inherited from FPSINPUT.WIP_LOTS_STATIC) |
|
ROUTE |
Route that has threading requirements (* inherited from FPSINPUT.RTG_STEP_THREADING) |
|
START_STEP |
Start step that will impact the future thread step rank in RTG_TOOL_ASSIGNMENT_LOT (* inherited from FPSINPUT.RTG_STEP_THREADING) |
|
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) |

WAIT_SEC_TO_SCHED |
The lot may be scheduled but must not be allowed to dispatch or start until this number of seconds has elapsed. (* inherited from FPSINPUT.WIP_LOTS_STATIC) |
