How to settle qty to material and costs to cost center?

Hi,

We have a requirement to settle the quantity part of the production order to a non-valuated material and the costs part of the production order to a cost center.

Our question is as follows :-

1) During GR to inventory will the production order's costs balance remain as it is (since the material is a non-valuated material) so that it can be settled to a cost center (as a variance) during settlement? We expect only the quantity to be updated in the material master and not the costs during GR.

If the above does not work then in plan B, we can still use a valuated material and set the standard price to zero so that the full order balance will still remain in the production order so that we can settle it as a variance to a cost center.
