View FPSBASE.CTM_REF_FOR_ROUTE_STEPS

This table exists purely to speed the load of RTG_ROUTE_STEPS_PLUS. Since CTM_SUMMARY loads much less frequently that RRSP we can refresh this table after CTM_SUMMARY and then each RRSP load is significantly faster.

Column

Comment

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)

ROUTE

Route that has threading requirements (* inherited from FPSINPUT.RTG_STEP_THREADING)

STEP

A single processing step within a route representing a single tool visit. Step is often a very complex string and should rarely be displayed. Instead we should use process_display. (* inherited from FPSINPUT.RTG_ROUTE_STEPS)

EST_SMP_PCT

Smp_pct tells you what percentage of the lots complete on a tool. Some sites skip steps by jumping over them so we see the lot move from step 3 to step 5 and we only know that it jumped step 4 because step 4 is on the route between 3 and 5. Other sites skip steps by moving lots into them and then moving them out a second later so we see a move from 3 to 4 at 11:11:11 and a move from 4 to 5 at 11:11:12. We do not care how it is done but just that the lot did not process at step 4 -- and to be more specific that no tool capacity is required to process this lot at step 4 and no cycle time is accumulated at step 4.

LINE_YIELD_PCT_TO_EOL

Line yield percentage to end of line is the percentage of units expected to successfully complete the remaining steps on the route. Normally we multiply the line yield of all remaining steps for the Capacity Model but entering a value in this OVR table manually overrides that calculated number. (* inherited from FPSINPUT.RTG_ROUTE_STEP_EQPTYPE_OVR)

TCT_SEC_TO_EOL

FIFO_STEP_SEC_TO_EOL

This can be used for critical ratio to avoid the following situation. Lot A of prd A and lot B of prd B are both at the same step on the same route. Plan CT for A is 40 plan CT for B is 60. Due date for A is in 41 days. Due date for B is in 59 days. Normal CR says A is one day ahead and B is one day behind so run B first. But this is insane because both are on the same route with exactly the same steps coming up and B is only "behind" because of a lower expectation. We should run A first. If we use FIFO then both are something like 50 days CT and A is 9 days behind and B is 9 days ahead. However there is a problem with this strategy because we would basically let B sit around and do nothing for 20 days until it was also 40 days and then have to run it at the same rate. So this is not perfect either. (* inherited from FPSBASE.CTM_SUMMARY)
