For the demand. I have an open SO for 4 delivery dates for one purchased part. The buyer has already opened a PO with four lines on it buying the part and scheduling the delivery to coincide with the date of need. I would expect the plan to see the open PO and count it as a scheduled receipt. Instead, when I run the plan, it suggests I cancel the four lines on the existing PO, and open a new PO with the same four lines… The vendor number in the item master is the same vendor number on the open PO. What would cause this? I welcome your comments…
Hi Something in the demand will have altered since the PO was loaded and the rest is down to item and system settings. For instance is the item set to lot-for-lot with a zero reorder cycle? Have a look here as well: http://www.mbsonline.org/forum/topic.asp?TOPIC_ID=10469
The item is a buy part WITH A req. method of purchase; it has no safety stock, no min-max, no reorder points or quantity. It is lot for lot. The dates the system suggests are exactly the dates on the existing order. If something changed, I would expect to see a ‘change’ suggestion to the existing order and not a ‘cancel’ one. Moving schedules in or out on existing orders is preferred and more cost effective and efficient that creating new ones. Come to think of it, all I ever see are New and Cancel Msgs. why would that be? Also, I am running MPS and MRP, my setup is correct so I can run either or both, and yet the worksheet DOES NOT get populated with a yes checkmark for any of the items in the MPS column. From the documentation, I thought that the finished goods from the sales orders would have been candidates for that. We do not use any forecast file
Hi Julia Because of the complex nature of this setup as you will have already read many many circumstances exist where you will get a cancel and new and not a change - some users have requested to set the system up in ths specific manner. I would suggest you get your NSC in to look at this, alternatively you will have to list every item setting, the manufacturing set up flags and all of the parameters on the sales and purchase orders - naturally this is not easy to analyse in this medium. If you are never getting a change I suggest you look at the reorder cycle setting on the items (as you said you are set to lot-for-lot), the planning flexibility field on the works orders, and the dampner settings in the set-up. However these will only come into affect if something changes which you are saying it does not. I presume you have had no modifications in this area?
Thanks for your input, I do enjoy reading your suggestions to all the questions. I have already posed the MRP issues to my NSC, but have not received a response. They do not have heavy duty manufacturing talent at this time, this is a show stopper for us, and we have 23 more companies to implement! I will resend my request to them today. Thanks, J.
Hi Julia If you get nowehere with your NSC, although I am sure you will, come back and I am sure we can sort something out - remote dial in? Or just listing the item, demand and supply settings so I can try and replicate what you are seeing. This will probably be easier to do over email, so drop me a line if you wish.
The Base Functionlity of Navision whatever is happening is Correct with respect to the Best Practises. Why i say this – if u had an Exp with othe ERP System it works in the similar fashion for Eg: 11i ,SAP & JDE . whenever there is a new demand/Run an MRP and you try to calculate the Net Req the Apps will definitely suggest for a New PO with the same lines of the Old PO what ever u have mentioned . Julia if your Tech Person and if u look into the Code Unit you will find the Apps works with out any flaw. You cannot Change & Run the Application by Changing the to your Business Operation .You need to Change your Business to the ERP system – Thats why an Org selects an ERP system keeping in mind the “Change” or "Transformation"in the Business Practises . The Functional Consultants are the Best People to match the need of the Org . And Coming back to the Changes whatever your trying to do with your NSC . I am pretty sure that they will screw up the Entire Apps and you will be left with a mess. Oooops!!! Navision is not meant of Heavy Duty Engineering Companies. If you say your a Heavy Duty Engg Company . Then you will be missing so many things – like – No Engineering BOM,No Sub-Contracting Reconciliation,No Scrap Disposal,and what not… Therefore ??? Better pull in Expert Manufacturing Consultants and map your Business needs with the Small Duty Navision Software …These are only Opinions please E & O
Julia do you know what is the consequence happened for the posting which i had posted – have a look at the “UNDO” … That guy had made a patch and now he is debugging the match ----“hahahhaha…” finally he will land up in Stopping the “Business Operation” – Does’nt work .
Hi Julia Did your NSC get to the bottom of it? I am unsure of the last two postings - more opinion based I suppose!
