FPSAPP.DASH_P_WIP_LOTS_EXPECTED_SHIP

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)

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)

PLANPRD

Planning product used for all planning purposes. All lots with the same planprd are interchangeable to ship to the customer regardless of their prd, route, technology, wafer size, etc. For detailed information on prd vs. planprd see table comments in RTG_PLANPRDS. (* inherited from FPSINPUT.RTG_PLANPRDS)

PRD

Prd determines the route which is used to process the lot in the facility and what tools, recipes, durables, etc. can be used at each step. Prd also determines the next facility for the lot when it finishes its route. For detailed information on prd vs. planprd see table comments in RTG_PLANPRDS. (* inherited from FPSINPUT.RTG_PRDS)

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)

PROCESS

Process defines what occurs at a step. Different steps can share the same process if they are identical. Process should normally determine allowed tools and recipe although it can be overridden by step, route, prd, lot, and experiment for exceptions. Each process is dynamically assigned to one or more eqp_type-process_family combinations with use_pct. One process_family is determined to be primary. If grouping is done correctly, a process should only be one eqp_group with no crossover. (* inherited from FPSINPUT.RTG_PROCESSES)

MAIN_ROUTE

Primary route used by the prd. Excludes rework and alternate routing. We allow this column to be null in WIP_LOTS_VERIFY because we may not be certain what the main route is when we fix for missed events. In that event we trust the WIP_EVENT_HIST triggers has loaded the correct information into WIP_EVENTS_CURR_STEP. (* inherited from FPSINPUT.WIP_EVENT_HIST)

MAIN_RT_STEP

When lot is on a rework or alternate route, this is the step where it will return to the main route. We use this for planning purposes so we can calculate remaining steps. We allow this column to be null in WIP_LOTS_VERIFY because we may not be certain what the main route step is when we fix for missed events. In that event we trust the WIP_EVENT_HIST triggers has loaded the correct information into WIP_EVENTS_CURR_STEP. (* inherited from FPSINPUT.WIP_EVENT_HIST)

LOT_GROUP

Lot_group is a grouping of lot_family and is the highest grouping in the lot type hierarchy. There should be only a few values for lot_group, i.e. Prod, Dev, TW. We group WIP and moves by lot_group on the dashboard and we group cycle time calculations by lot_group so this is an important field. (* inherited from FPSINPUT.WIP_LOT_GROUPS)

PROCESS_FAMILY

See https://help.inficonims.com/display/DW/Guide+to+Process+Families. (* inherited from FPSINPUT.RTG_PROCESS_FAMILIES)

PLAN_PRIORITY

Permanent priority of the lot set in the MES generally by planning. (* inherited from FPSINPUT.WIP_EVENT_HIST)

STEP_ENT_INST

Time when the lot entered the step. (* inherited from FPSBASE.WIP_LOT_HIST)

STEP_SEC_NOHOLD_FOR_WSF

The FOR_WSF columns are used in populating WIP_STEP_FUTURE. This is based on the CTM_COLUMN_FOR_WIP_STEP_FUT column in GEN_FACILITIES. For example, if the value of that column is 7D_WAVG then we use the 7D_WAVG cycle times for WSF. (* inherited from FPSBASE.CTM_SUMMARY)

STEP_SEC_NOHOLD_FOR_WSF_TO_EOL

This is the expected seconds from the current step to the end of line not including time on hold. WIP_STEP_FUTURE is used for upcoming arrivals and should predict as if the lot will not go on hold unless it is known that it will. The result is that the predictions are reasonably correct for lots that do not go on hold or where we know the future hold - but very wrong for a few lots that go on hold that we do not expect. In contrast, WIP_FLUSH which is used for prediction completion of the route and all future routes will use the entire STEP_SEC including average hold. (* inherited from FPSBASE.CTM_SUMMARY)
