Milt, In my reply to Sean, I stressed a few points : 1. If you can afford an off-the-shelf archiving system, buy it ! 2. Strenuously test out anything that you write before going live. 3. Know the rules you need/want to work to. 4. The programs I wrote addressed the way we work, given the BPCS modules we use and how we use them. They seem to work fine for our company. Without some modification they almost certainly wouldn't be right for Sean. In my defence .... I know my programs aren't a total solution. When I wrote them we had particular problems and I wanted to address the areas where I felt we could benefit quickly. I archive data onto Archive files that remain on the box, I don't ever delete anything completely. I also have programs to quickly retrieve selected data (eg an order) from Archive to Live. I have enquiries and reports that work over the Archived data. I can think of a couple of files that I have missed re. Customer orders that I may need to look at, but I'm not sure what the 10 are you refer to and, given the way we work, if we would use them. We don't use Lot control or OLM. ITH history seems to continue to function OK. Yes, there are other areas where data can be archived that I haven't looked at yet. I only archive KMR records for Forecasts that are in the past. Our senior Planner did some extensive testing and came to the conclusion that we could function without these. My programs have been running for about 6 years now and, but for a few teething problems in the early days, the archiving of the data doesn't seem to have caused any problems. BUT, I STRESS AGAIN.... IF ANYONE ISN'T SURE, BUY OFF THE SHELF FROM A COMPANY THAT DOES THIS KIND OF THING.

In our view, minimum requirements for archiving software include: >> Strict compliance with the BPCS rules for purging data ... plus ... >> Additional verification logic to ensure that data that may appear to be ready for archival is not removed when, in fact, -- it requires further processing, or ... -- it's necessary for data history integrity, or ... -- premature removal would orphan other data. >> Archived data must support interrogation/reporting using existing BPCS inquiry and reporting programs. Locksmith Archiving software satisfies those requirements. www.unbeatenpathintl.com/locksmith_bpcs/source/1.html When we compared Locksmith functionality with the functionality Tom Molyneux described for his code we found that Tom had: *** Missed some critical files (e.g. 10 missed files in "Customer Orders" alone) *** Missed some important areas (e.g. OLM, ACP, ACR, User Profiles, Item Master, Customer Master, Vendor Master and Lot Master.) *** Apparently missed some crucial linkages (e.g. can't archive ITH without validation to ensure that lot history is not lost.) *** Archived some data that shouldn't be archived (e.g. KMR) Warmest regards, Milt Habeck Unbeaten Path International North America: (888) 874-8008 International: (262) 681-3151 www.upisox.com +++++++++ +++++++ +++++++ +++++++ +++++++ +++++++ From: McGovern, Sean To: SSA's BPCS ERP System Sent: Monday, February 12, 2007 3:53 AM Subject: Re: [BPCS-L] Data Purging Would you consider sharing your code ?

Some time ago we had problems, not so much with disk usage as the fact that, if left to it's own devices, BPCS builds up data at a staggering rate of knots and standard tasks begin to take ages to complete as programs plough their way through millions of records. To alleviate this and before I knew what archiving tools were available, I wrote some programs of my own to take data off live BPCS files and put them onto archive files that could still be accessed by in-house enquiries and reports and retrieved back to the Live system in case of problems. From there it would be a short step to actually deleting data to make disk space. I archive the following data : Customer Orders : ECH, ECL, ECS and ESN Shop Orders : FSO, FMA, FOD, FLT and ESN Purchase Orders : HPH, HPO and ESN Pick List Pribt File : IPP Print Detail Work File : ZPD Material Requirements File : KMR Inventory Transaction History File : ITH Promotions & Deaks Master File : PDM Special Prices File : ESP Cost Master File : CMF You need to carefully determine your criteria to make sure you don't archive/delete anything you need. After consultation with our Accounts Department, we also archived some old years off the G/L files - eg GLH, GHH, GSB - that were completed and this took off millions of records. So, if you can find software that does the job for you - great. But if not, there are ways of doing it yourself.
