MRP & Shop Order FSO_SRSDT 405 CD

E-mail really from Al Macintyre - using Tim's PC at work

When the Re-Schedule date from MRP in Shop Orders is a field filled with 9's
does that mean forget it - recommend de-expedite or even close the shop
order?

When Re-Schedule MRP in Shop Order is a real valid date
does that mean that instead of the original date created at shop order
launch time, MRP is recommending that we use this other date for what?
Completion Due Date or does it mean something else?

When Re-Schedule MRP in Shop Order is a blank field
does that mean that MRP has not yet hit the relevant items since the shop
order was released
or that the original due date is still A-Ok right on good correct valid?

Our latest scenario is that at one level of plant management they want shop
orders released to the point that the work force can be kept busy, without
waiting on additional data generated off the computer, or paperwork shuffled
through production control, while at another level of factory supervision
there is poor visibility regarding relative priorities between similar
orders, so they often end up producing sub-assemblies that are not needed
for several weeks, sacrificing raw materials & worker capacity that results
in stuff that was due last week not getting done.

One idea in the works is to replace the intermediate work file of SFC230, in
a clone of that software, leaving vanilla intact, with one that is sequenced
by real due date, wire gauge, wire color, electrical attachments, etc. and
replace prompt screen to offer range selection based on facility and
department.  So I am interested in where & when the MRP Re-Schedule Date in
the Shop Order comes from.

Although we report labor via JIT, we mass release our shop orders via SFC,
then occasionally manually release individual orders based on customer
panics.

Thanks for any clarification.
