Table FPSINPUT.WIP_DEMAND"

Committed demand by planprd. We use this to generate demand dates for each lot. See the extensive comments in the header of the WIP_FLUSH_REORDER_DEMAND procedure for details.

Schema: FPSINPUT
Tablespace: FPSDATA
Primary key: FACILITY, PLANPRD, LOT_GROUP, DEMAND_INST

Column	Type	Nullable	Comment
FACILITY	VARCHAR2(6)	N	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. (* from FPSINPUT.GEN_FACILITIES)
PLANPRD	VARCHAR2(64)	N	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. (* from FPSINPUT.RTG_PLANPRDS)
LOT_GROUP	VARCHAR2(8)	N	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. (* from FPSINPUT.WIP_LOT_GROUPS)
DEMAND_INST	DATE	N	Start of period when this qty of this planprd needs to finish. We automatically spread demand across each plan week in WIP_DEMAND_BY_WEEK which feeds WIP_FLUSH therefore this column can be the start of any time period less than or equal to plan week. It could be the demand for each shift or for each day or for each plan week but if the site has no preference then the easiest way to set this up is to write one row per plan week and let us spread across that week. It is important to note that we always spread across the plan week with our custom logic so even if this table is by day we might adjust it to another day within the same plan week.
DEMAND_QTY	NUMBER(9)	N	Number of wafers committed in the demand.
