FPSADMIN.CTR_P_WIP_LOTS

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)

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)

STEP_ENT_INST

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

TOOL

Tool is generally just the main tool. The exception is when different entities on the tool run completely independently and it is physically impossible to run wafers of the same lot across multiple entities. In this exception case, we may want to assign the entities to different eqp_types and therefore we should define each entity as a tool. Please note that when we do this there is no indication whatsoever that these different entities are on the same tool. (* inherited from FPSINPUT.EQP_TOOLS)

ROUTE

Route that has threading requirements (* inherited from FPSINPUT.RTG_STEP_THREADING)

DUE_INST

To indicate the due date for this futuer start lot (* inherited from FPSINPUT.WIP_STARTS)
