FPSINPUT.SCH_P_ADMIN_CHK_BATCHED_CURR

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)

SCHED_GROUP

This is the grouping of tools and processes which the FPS Scheduler schedules together. Since this is a parent of tool via tool->process_group and a parent of process via process->process_group, by definition each tool and each process can only be in one sched group. We need all related tools and processes to be in the same sched group for efficient scheduling. One example is sinks and furnaces because of queue times and batching. Another example is for smaller facilities like Assembly or Test where we might schedule the entire facility together. (* inherited from FPSINPUT.RTG_PROCESS_GROUPS)

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)

NWSCH_START

BATCH_CRITERIA

Lots that can run on the same batch TOOL and have the same value of BATCH_CRITERIA can run together in a batch. Therefore this is a critical column for scheduling on batch tools. If BATCH_CRITERIA is not populated, Scheduler defaults to the assumption that any WIP with the same EST_MACHINE_RECIPE can be batched together. Keep in mind that many MESs have additional constraints on batching (for example, that all WIP in a batch has the same SCRIPT_ID) and these must be incorporated into BATCH_CRITERIA to ensure that the batches are allowed by the MES.
