Master Planning Action Messages

Report

Posted on by kpm

Master Scheduling is generating action messages on planned orders. For example, it may produce a "Cancel" message on a planned order. Firming that Cancel message creates a purchase order, which doesn't seem to make much sense. Is there some setting to bypass the creation of action messages on planned orders? What is the purposes of those messages? Is there any documentation that discusses the rules behind the creation of planning messages in general, and describes the consequences of firming those messages?

RE: Master Planning Action Messages

Not at all ridiculous, if you would not to implement the first suggested action to increase you will be short of material. The complexity of the system generate these kind of "strange" actions when it's not properly setup. I guess you should disable messages for increase and your problem will be solved.

RE: Master Planning Action Messages

Another scenario where you'll get a cancel action on planned supply order is if the parent order needing the supply has a cancel action on it. For example, someone releases a production order to build something that was not suggested by MRP/no demand. Since MRP doesn't read our minds, it won't know whether to support this parent order by planning the components, or assume we will pay attention and cancel the parent. Therefore it supports both scenarios--planned component order but also flagged for cancellation. It's up to us to pick which of the two actions we will take--proceed with the components or cancel both the parent and component orders.

You'll get a Cancel message on a planned order (or a purchase order) if the system has set an Increase message on an earlier order.

I can see the point of cancel messages on say a purchase order or production order if you delete a sales order (that created the demand) - but I'm not sure that they are used much.

I have disabled "Decrease" the Actions for Cancel of Purchase Orders do disappear as stated in this thread. When I run the Actions Report, I still see a lot of Cancel lines. Does anyone take advantage of this functionality?

Re: Master Planning Action Messages

You can disable the action message for "decrease". Becuase a cancel message is a decrease message, this will stop the cancel messages for planned orders but you will also miss any action messages to reduce quantity of existing orders. Otherwise in the past years with customers I have seen the users just live with it and filter out any planned orders with a cancel message. When you firm them you are going to over-order (although the next MRP run would generate a cancel message for your firmed order again) . Nothing has changed in 2012 regarding this behavior.

Have any changes been made in AX 2012 with regard to creating planned orders with an action to cancel? (I notice this blog started in 2010) I am running into this in AX2012 and just wanted to see if any new options exist. Thanks!

I noticed that several of the futures messages we get are related to Safety Stock - Min.Max. Anyone else notice this and how have you dealt with it? I cannot get my head around why the system won't release the safety stock instead of pushing the order out. Why doesn't it just plan another requisition or planned order. Also, it works very different on purchased parts and manufactured parts. Our purchased parts are set to Today + Procurement time. However, this setting does not work on manufactured parts. The only option on manufactured parts is today, which you will never accomplish, especially if you are using FIFO.

Re: Re: Master Planning Action Messages

Planned purchase orders are generated based on 'Just in time' inventory - so (like in Brian's example above) if you have an existing purchase order covering a existing demand, and a new demand is created [for a later delivery date] you have two options: Either process two purchase orders, order reciepts, and purchase order invoices, or process one, larger purchase order. But in the second case your average on hand inventory increases. Which is best? Lots of small quantity transactions, or fewer, larger transactions with a higher average inventory carrying cost? There is no simple answer to this, so it's a value judgement, and one thing the action messages are doing is indicating that you have to make the decision.

But the system's not perfect. Why for instance do you get an action advance message on a future dated purchase order receipt which is late relative to the demand it's covering but a futures message on the demand?

Re: Re: Master Planning Action Messages

I absolutely agree. It is ridiculous to generate cancel messages for planned orders. Why plan it in the first place? We have greatly minimized ours with the positive and negative days, however.

Re: Re: Master Planning Action Messages

Like most people using master planning I think it is ridiculous to generate cancel messages for planned orders. The system creates that planned order in anticipation of the user NOT acting on the action messages.... it clutters the system with planned orders you have to ignore. it was a very bad design idea. No parameter will get rid of them, we have explored every avenue. With the positive and negative days the user has complete control when the system will suggest to use an existing order and when it will ignore existing orders and create a new planned order. The sobering reality is that it ALWAYS creates that planned order, in one case without action mesages, in other cases not. Brrr. We have to change the code.
