FPSAPP.CM_P_FACILITIES

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)

FACILITY_DISPLAY

The name of the facility displayed on all dashboards and reports. Facility is a short field since it is used in every join so we allow a longer more descriptive name here although often this will be the same as the facility. (* inherited from FPSINPUT.GEN_FACILITIES)

FACILITY_SORT_ORDER

QTY_UNIT

Defines the unit used to measure number of quantity. The key here is that this quantity must be known throughout the entire route through the facility. For example in a sort facility where lots enter in wafers and are broken into die but the number of wafers is still known when the lot completes the facility then the qty_unit must be wafer. It cannot be die because die is not known when the lot enters so die will be the sec_qty_unit. Similarly at a final test facility where the lots enter with both wafers and die known but only die are known when the lot completes the facility then the qty_unit must be die. It cannot be wafer because wafer is not known when the lot completes so wafer will be the sec_qty_unit. Please note the entire process from only wafers to only die must be split into at least two facilities because of this requirement. (* inherited from FPSINPUT.GEN_FACILITIES)
