Want to avoid physical reserve on materials received...

Hello everybody, after running Master Planning and firming items to purchase order, and receive them, the items planned are automatically physical reserved by the production order that was created, in my scenario, I do not want them to be reserved, so I select in production paramenters Reserve-Manual, but it is still physical reserving those materials, after receipt…

Am I missing any other parameter, any clue on this? Many thanks!!

Are you sure they are reserved, don’t you mean marked instead?

Is it a requirement based coverage group?

Looking into the “Inventory Available” section, the column Physical reserve shows the full quantity that was received. And if I want to transfer the stock to another warehouse, it doesn’t allow me, it says that there is not enough inventory available (becouse it is already reserved in the warehouse that was received). The inventory dimension has warehouse as mandatory…

Yes it based on a coverage group (for production materials). I’m translating from a spanish version so may find some different sintax in the english version.

So by entering a sales forecast for the finished item, the mps creates the production order for it and all the materials required, these materials are the one that are reserved for the production order that I also firmed-up. In a recent scenario, if I receive the components before firming the production order, they are not reserved… that was why I put in the production parameters Reserve-Manual, but it is still reserving the materials.

In the Master Planning paramenters, I change in the Standard Update tab, Firm-Marking update = None, it is still doing the same…

Yes, it is a Requirements based group.

When you firm it would obey the reserved flag in the parameters. Not sure if this is written at the time of the order, doubt it, but changing the parameter would oly affect the next planning run, so you need to test this on brand new orders. I am not sure but if it is a requirement coverage group this may also have an impact as it will stamp the sales and production order relationship, which would imply reservation.

I suggest you initially try it manually with a new order - not MPS. Take it all the way to start - the picking will then reserve. It should not do it before this.

Then run the same through MPS, it may reserve because you are tying the supply anbd demand by the requirement type.

Let us know how you get on.

Thanks a lot Adam and Fabricio, it was ver y strange as within the same environment, the model didn’t work for me but works fine for other user, the materials were not reserved after firming the production orders. It -seems- to us that the parameter that made this effect was in the Inventory Management module, Inventory parameters, Transport tab, Automatically reserve items (unchecked)…

The rest of the scenario was always the same so that is our conclusion.

Thanks again, Héctor

Thanks Hector, nice catch.

Guys… after more tryies the cause of all was the Warehouse dimension, that was checked for the “Coverage plan by dimension”. If it is checked the master planning calculates the requirements for the warehouse stated in the bill of materials, and once the materials are received are automatically reserved in the same warehouse, all the planned quantity, so there might be nothing else available to move to another warehouse (that was our situation).
