My biggest issues with BPCS calculation of MPS are related to distribution 
requirements.  If you have a single shipping location using these functions 
should be much simpler.  Other issues that I've noted are as follows:
*       The dynamic minimum balance calculated from horizon days and minimum 
balance days is not really dynamic.  By this I mean that BPCS uses the current 
values for the calculation then applies the result to the end of time, 
regardless of demand changes.  This means that if you have high demand now your 
minimum balance will remain inflated.
*       MPS and MRP calculations do NOT consider expiration dates on inventory 
lots so that if all of your inventory is about to expire MRP will NOT tell you 
to order more.
*       The exception messages tend to be a lot of trouble because there is no 
sensitivity setting.  You tend to get a lot of move in / move out messages that 
only change the delivery date by a day or two.
*       Ignores orders entered in to a past due date as Al Mac points out.
*       There is no functionality to allow for stock based substitutions or 
engineering changes.
I hope that this helps but the most important thing is to make sure that the 
users are fully aware of what each of the planning codes is intended to 
address, not only mathematically but functionally as well.  APICS education can 
be a great asset at addressing this issue.

Subject:        Starting up the MRP module

I'm on V4.05CD.  We've never implemented MRP, MPS, etc., etc.  We are using
SFC, PUR, INV, ORD in a 1960's type of computing environment and I've been
charged with starting MRP up and using it.  We manufacture carbide cutting
tools - buy a piece, grind on it, maybe do an outside service to it, inspect
and shelve (or ship) it.

We have some extremely knowledgeable manufacturing guys who can interpret
MRP terminology and, with my assistance, convert it to BPCS-speak.  My
question is are there any unexpected gotchas in MRP?  Will I come in to work
one morning to be greeted by irate users, upset management and the always
dreaded pink slip?

Thanks in advance

Thanks Roy, for your kind remarks.
My outline was not every detail exhaustive, just an off-the-top-of-my-head
outline to help Krys
and Juan get started reviewing BPCS_L archives and their in house
I often have a hard time balancing constructive for newbies without
annoying those already familiar with the obvious answers.

14. Visit home page then look at Midrange
Resources.  Search there for BPCS (17 hits listing outfits that provide
BPCS services and have decided to have themselves listed there ... many
BPCS places are conspicuous (to me anyway) by their absence here.)

One of the places listed is Crowe Chizek, which I mentioned by implication
in my previous post, because they are heavily involved in BPCS user group
conferences sponsorship.

15. Return to home page.  Search there for BPCS.  First
on list shows us AS/400 FAQ has a place for BPCS FAQ and we've obviously
been neglecting it.  That would be a good place to put the answers to
recurring questions.

16. Speaking of AS/400 FAQ -> General -> List of User Groups (Question # 3)
reminds me of broken links I overdue repairing.  1/2 way down are links to
two Ohio AS/400 user groups that might be good start places for  Krys and
DeeDee (if you not already know of such places)  For everyone else, in the
rest of the 400 world, looking for a user group, there's

17. If your company does not now have a satisfactory BPCS educational and
enhancement consultant and you seeking one, there are many fine resources
on this BPCS_L., and happy customers here who can recommend their
favorites.  Don't forget to put the moderator of BPCS_L near the top of
your candidates list.
