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.

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?

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 possibilities. I often have a hard time balancing constructive for newbies without annoying those already familiar with the obvious answers. >Al: > >What a great compendium of resources. > >If I was a BPCS support person I'd print the text of the message and hang it >over my desk as a ready reference. > >Roy Luce 14. Visit www.midrange.com 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 www.midrange.com 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 http://www.eserverusergroup.org/ 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. - Al Macintyre (email@example.com via Eudora) Al's diary http://radio.weblogs.com/0107846/ Cure cancer. http://members.ud.com/about/ -- _______________________________________________ This is the SSA's BPCS ERP System (BPCS-L) mailing list To post a message email: BPCS-L@midrange.com To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/cgi-bin/listinfo/bpcs-l or email: BPCS-Lfirstname.lastname@example.org Before posting, please take a moment to review the archives at http://archive.midrange.com/bpcs-l. _______________________________________________ This is the SSA's BPCS ERP System (BPCS-L) mailing list To post a message email: BPCS-L@midrange.com To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/cgi-bin/listinfo/bpcs-l or email: BPCS-Lemail@example.com Before posting, please take a moment to review the archives at http://archive.midrange.com/bpcs-l.
