FPSAPP.SCH_P_CURR_DURABLE_COUNTERS

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)

SCHED_GROUP

This is the grouping of tools and processes which the FPS Scheduler schedules together. Since this is a parent of tool via tool->process_group and a parent of process via process->process_group, by definition each tool and each process can only be in one sched group. We need all related tools and processes to be in the same sched group for efficient scheduling. One example is sinks and furnaces because of queue times and batching. Another example is for smaller facilities like Assembly or Test where we might schedule the entire facility together. (* inherited from FPSINPUT.RTG_PROCESS_GROUPS)

DURABLE

Durables are either reticles for Litho or probe cards for Wet or Sort. A durable can either be in a carrier or at a location without a carrier. (* inherited from FPSINPUT.RTG_DURABLES)

COUNTER_UNITS

Unit for the maintenance counter. Common examples include wafers or hours or kWh. (* inherited from FPSINPUT.EQP_MNT_FUTURE)

COUNTER_MAX

the maximum usage of this counter (* inherited from FPSINPUT.RTG_PROCESS_COUNTERS)

COUNTER_LEFT

the current available amount left of this counter (* inherited from FPSINPUT.RTG_PROCESS_COUNTERS)

MNT_NAME

Name identifying the scheduled maintenance event which is unique for the `logged_entity`. For example, daily qual or weekly PM. (* inherited from FPSINPUT.EQP_MNT_FUTURE)

COUNTER_MSG

the counter message on the durable (* inherited from FPSAPP.SCH_W_SCHED_DURABLE_INSPECT)

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)

WAIT_SEC_TO_SCHED_PRTY

this is used to delay the schedule for the priority lots if it chooses delay_schedule as the wait_to_sched_method (* inherited from FPSINPUT.RTG_PROCESS_COUNTERS)
