Hi Hans I am surprised you dont get action messages such as "expedite" on the purchase orders. Could it be these action messsages only apply on planned or firm planned orders, not on purchasr orders? On your second question, the net change will filter items with the activity code set to Yes (CIC.ICACT = Y). This CIC.ICACT gets reset to Y by other programs when there is activity on the item such as new orders, inventory transactions, etc. I have noticed before a planning parameter change, such as a minimum balance quantity change, does not change this flag to Y. So running a net change MRP after changing some parameters, did not yield the expected results. I prefer always running full MRP regeneration. I dont know which other programs or activities will change the value of CIC.ICACT to Y. > Daniel Warthold Business Analyst > Eicon Networks Corporation > > -----Original Message----- From: Hans.G.LOEF@xxxxxxxxxxxxxxxx [mailto:Hans.G.LOEF@xxxxxxxxxxxxxxxx] Sent: Tuesday, March 08, 2005 09:02 To: bpcs-l@xxxxxxxxxxxx Subject: [BPCS-L] MRP calculation and Net Change versus Regenerative We are running BPCS V 6.1 GA without any BMR but with a lot of own modifications but the MRP programs haven't been touched by this modifications. We are (once more) intending to improve the MRP usage of our BPCS. In general the MRP works well if all parameter / conditions are properly set up. First issue: Currently we face the following issue. Our central sourcing dept. would like to use only annual purchase order for raw metals e.g. a huge quantity to supply the yearly demand in one PO line on one due date. I did some tests in our TRAINING environment and BPCS MRP is reacting as follows (depending on stock situation) if the PO is settled up for Jan 1st. the requirements are decreasing the PO quantity through the year, and there is no other MRP action. PO is settled up for Dec. 31st. the projected on hand is going negative until the PO due date is reached, and there is also no other MRP action. PO is settled up with PO line per period (weekly/monthly) the projected stock on hand will be balanced per due date of the PO lines, but there is no MRP message. Following our expericend from shop order/planned order I was expecting that some MRP messages e.g. Cancel, De-expedite, Expedite, LT Violation, Past Due or Release. But none of them came up after the MRP calculation run (MRP600) for the P.O. mentioned before. -- the PO have been created via PUR152 as scheduled ones for raw material. Secondly: The difference between Net Change and Regenerative is that only items which need to be re-planned are treated during the Net Change. For me the result should be the same. If there is any need to change, the MRP will propose to act. The difference might be that "R" will crate new records in KFP/KMR and "N" will keep those which haven't any different order/demand situation as before and I guess that this is implicated by the Activity flag (see MRP300) or am I wrong. Thanks for any tip/advice concerning the above. rgds/mfg Hans-Georg Loef Impress central MIS Bahnhofstr. 16-17 56575 Weissenthurm Phone: +49 (0)172 516 36 45 e-mail: hans.g.loef@xxxxxxxxxxxxxxxx ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- -------------------- Discover Impress on http://www.impressgroup.com The information contained in this e-mail and any attachments is strictly confidential and may be legally privileged.
