View FPSBASE.ETP_ENTITY_SHIFT_HIST_NOW
Unions ETP_ENTITY_SHIFT_HIST table with the realtime data for all shifts not yet in the history. The previous shift is never in the history since we do not load until one shift has past to allow for post-updates of the etp_state. This view includes the partial data for the current shift. IMPORTANT NOTE: This view uses DASH_B_H_ETP_7D table for speed but that table only has data for either EQP or ETP whichever one is active on the Dashboard. Therefore this view will return data for the previous and current shift only if ETP is active! This works perfectly for the Dashboard as long as we are still using the flag. In a future version, we will show both EQP and ETP together and at that time we will have to populate two different DASH_B_H_xxx_7D tables and modify this view accordingly.

START_SHIFT |
Shifts can be of any length and it is important that all queries get the shift length based on start_shift and end_shift rather than assuming a set number of hours. (* inherited from FPSINPUT.CAL_SHIFTS) |
|
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) |

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) |
|
ENTITY |
The lowest level of the equipment hierarchy that an event can be logged against. Tools, subtools, shared parent tools, chambers, ports are all entities. Load locks are also included although we consider them as ports. (* inherited from FPSINPUT.EQP_STATUS_VERIFY) |
|
ETP_STATE |
If entity is down then use eqp_state directly. If entity is up then determine etp_state from proc_state and sby_state. (* inherited from FPSBASE.ETP_STATUS) |
