View FPSBASE.WIP_REF_HOLD_ESTIMATES
This view calculates the estimated_hold_sec for each process_family, hold_type, lot_group based on data from the last 28 days. These are the default values for estimated hold seconds and the values for remaining hold seconds are half of these estimated values. If you wish to use historical hold time by prd, route, step, and lot_group instead of these values then you set the use_ctm_bef_est_for_release flag in GEN_FACILITIES. Either way, the defaults can be overridden by ovr_estimated_hold_sec and ovr_remaining_hold_sec in WIP_HOLD_TYPES or more specifically by ovr_release_inst in WIP_LOTS_VERIFY. Please see the column comment on ovr_remaining_hold_sec for an example of how estimated and remaining are used to calculate the estimated release inst of all lots currently on hold.

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) |

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

HOLD_TYPE |
Generally hold_type will come directly from the MES. (* inherited from FPSINPUT.WIP_HOLD_TYPES) |
|
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) |
