View FPSBASE.CHK_WSF_CURR_STEP
This view finds discrepancies in WIP_STEP_FUTURE as compared to WIP_LOTS_REALTIME. The results of this view are fed to ADM_FIX_WSF_CURR_STEP procedure which loops through the lots and calls the normal UPDATE_WIP_LOTS_REALTIME and/or UPDATE_WIP_STEP_FUTURE_ONE_LOT procedures. Because we normally only update WIP_STEP_FUTURE when a lot moves and we do not insert rows if the route/step is not in RTG_ROUTE_STEPS_PLUS, these discrepancies normally occur after RTG_ROUTE_STEPS_PLUS is refreshed with a new record for the current route/step. However if we see fixes made after each lot even when RRSP did not refresh that would indicate a problem. Please note that checks on the entire WIP_STEP_FUTURE table including future steps are done in ADM_FIX_WIP_STEP_FUTURE.

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) |
|
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) |

ORIG_FAC_LOT |
When lot is duplicated for shared facilities, this is the original lot. This will also be the part of the duplicated lot before the slash but having this column avoids needing to parse. For example, in the record for lot ABC123.0/FAB1, this value of orig_fac_lot will be ABC123.0. (* inherited from FPSINPUT.WIP_LOTS_VERIFY) |
