The TDASys
Difference Between Scheduled
and Current
Job Locations for Production Control.
Many of the custom ODBC reports
illustrated are apparently similar to some of the standard INFISY/Global
Shop reports. However, there is a subtle yet substantial difference between
the two sets of reports. The standard reports base all of their Production
Control calculations upon a Work Order's scheduled location, in other
words where a job is scheduled
(supposed) to be. These ODBC reports are based upon each job's current
location. In other words, where the job is actually
located - not where it is scheduled
to be.
As an example, consider a
job that as of today was scheduled to be half way through machining in
the CNC-Mills, but is actually running three days late, stuck in the CNC-Lathes.
Production Control reports trying to ascertain; job status, work center
load, delivery time, etc. which are based on scheduled
location of the job will be off by 3 days. And if the job remains stalled
at it's current location, with each passing day the job will grow increasingly
late and reports based upon scheduled
location will become progressively less accurate.
The ODBC reports illustrated
here are based upon a Work Order's current
location. In the case of the above example these reports would continue
to show the job as located in the CNC-Lathes until the day when that job
finally moves on to another Work Center. The advantage of these reports
is obvious. Returning to the example, tomorrow a Work Center Load report
for the CNC-Mills using scheduled
location will ignore the Work Order described above - because the job
is scheduled
to be out of that Work Center. However, reports using current
locations will shift the workload created by this Work Order back into
the previous Work Center (CNC-Lathes). Production control will see that
this job hasn't arrived at the CNC-Mills yet, and will be able to plan
accordingly.
