Remove reservations from quarantine orders

Hi,

Is there a way of making the daily MRP run ignore stock in our quarantine warehouse?

We have two warehouses - a main stores and it's equivalent quarantine warehouse. Purchase orders are received into main warehouse via quality orders, or into the quarantine warehouse if they fail the quality order.

Sometimes we have fialures in production that could not be picked at goods-in, and for those we then manually create a quarantine order. We use quarantine orders as it is a good way of recording the details of the failure.

My problem is that the quarantine orders create reservations between the quarantine warehouse and the main warehouse. When MRP is run on the mian warehouse it sees the stock in quarantine and assumes it is available to use, which I do not want to happen.

I have tried switching the quarantine warehouse coverage to manual and I have switched off reservations but then I lose works order requirements. None of these work.

I cannot figure out a way of making MRP ignore stock in the quarantine warehouse, so any advise would be appreciated!

We have AX2012R3, and I am a user with access to the set-up screens but not a developer.

Thanks

Andy

Hello Andy,

about the mrp as i know, you can not avoid the ignoring with customization, which i do not recommend, but for the failures in the production, why do not you use non conformities instead of quarantine orders.

Except of that you want the material is not sold or something.

best regards

Hi Albrecht

Thanks you for the reply, I had not thought about non conformances so I will investigate.

It is a shame that the quarantine order system does everything I want it to do apart from the problem with reservations!

HI Albrecht,

I have tried the non conformance but unfortunatelty they do not stop the stock being used or being visible to MRP. Thank you for the suggestion though

Your problem is that the system "has" to assume the stock in quarantine "will" be available once it has passed quarantine, otherwise you would purchase something, it would be received and would "disappear" and then MRP would urgently tell you to purchase more. So making it ignore the stock is the wrong way to go. The production order based issues you could raise at a production quarantine warehouse, this would have no cyclical relationship for Planning to see so would be ignored. As for the standard ones you need to assume all will come out of quarantine or build in scrap and safety stock into the supply chain.

Hi Steven,

Thanks for the replay - I appreciate that what I am looking for is not "normal". My problem is having material in quarantine that may or may not be usable at some point, but I don't want MRP to assume that it is.

For us, the risk of re-ordering regularly used material is a lot less than not re-ordering.

The reason for wanting to use the quarantine order is that there is a record of the failure - the nature of the problem, qty, etc - on AX, so we can easily see what we have in quarantine and why by looking at the open quarantine order list. I could just transfer the stock to the quarantine warehouse so there are no reservations, but then I lose the details of the failure on AX as there is no quarantine order and it would all have to be logged off line. Does that make sense?

I assume there is not way of referencing a quarantine order number on a warehouse transfer other than just naming the transfer journal after the quarantine order?

Cheers

Andy

Why not look at quality orders and stock status and look at the nettable MRP elements there. However you will constantly be told to reorder what you have the moment it is received, because if you do not want the system to assume it is usable that means you assume 100% failure rate so it would reorder every time. I would look at buffers and scrap factors in the supply chain rather than continual multiple reordering elements you dont need, but that is of course up to you. The other option is to customise MRP to ignore the Quarantine chain, which I would not recommend because of the constant reordering, but it is something you could investigate.

Thanks Steven.....I don't really want to go down the customisation route, I was more hoping there was just a box that could be unticked at user level or something like that.

I think it's going to be back to the drawing board!

Some systems differentiate between inventory pending inspection which is expected to be available to mrp, and on hold which is not expected to be available.

Conceptually if you in an item in quarantine and then raise a rework order then mrp would not be able to plan it against other demand. The expected receipt of the item once the order is closed will be seen by mrp as a future supply.

In practise I have not seen any customers use Quarantine orders. The suggestion by Steven of a separate warehouse ignored by mrp is the most practical solution. In effect it just means you use your own Quarantine warehouse than the one Ax uses - the work to move stock in and out of either is much the same . You don't necessarily need to move the stock physically it could be a virtual warehouse with same location structure.
