I am not familiar with version 4.05 - but a modification or using BOM structures is not necessary in version 6.0.04. By using the Alternate Item INV180 relationship and the Item Status Code INV195 - the system can automatically substitute one item number for another at order entry time. The item that is substituted will be what MRP plans for (based on the planning records for that item). There is no need to 'fool' the system by using BOM structures or re-stocking inventory under a different number. The order line item is updated at order entry time automatically. A message is displayed to the data entry personnel at order entry time that indicates the substitution was made, and a note automatically added to the order entry line by the system that states item xyz was substituted for item ABC. It is fairly simple to set up and use. -----Original Message----- From: MacWheel99@aol.com [mailto:MacWheel99@aol.com] Sent: Monday, February 25, 2002 3:30 PM To: email@example.com Subject: Re: Alternate items Here is a suggestion ... I am sure there are other ways ... what I think is important to come up with a consistent way that is understandable to all your employees, and has suitable safeguards against human error. Book customer order for item # 11.123 ... in item or customer notes MPN ESN mention that 11.123 customer item is same as M123 in internal inventory & production, and decide where to print that info, such as documents used by shipping department to locate inventory ready to be shipped. BOM for 11.123 would be 1 @ M123 ... in that item notes you might mention that this is same as 11.123 & you have to track it the 2 different ways for the 2 different purposes customer order for 11.123 will drive MRP to have you produce M123 look into inventory transaction effects to see if your version of BPCS supports a transaction that would be like INV510 except instead of moving inventory from one location to another, you moving it from one item to another, redesignating 11.123 as M123 ... you may want a modification in which a person keys in the quantity & one of the item #s & up pops the corresponding item# & you say which way it is going between the two of them. You will need capability of other direction if customer returns 11.123 for repair if there are any alleged quality problems that slipped by You might put in the last routing step of M123 a reminder for someone to do that transaction to transfer what was produced to 11.123 MacWheel99@aol.com (Alister Wm Macintyre) (Al Mac) _______________________________________________ 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.
