Procurement Type form CN33

[fortian]

When I transfer into the project an item of a BOM with item category L, using transaction CN33 I always get Procurement Type: PReq + Reservation for WBS Element.

I would like to get only Reservation, not PReq.

I thought that it had something to do with the Procurement Indicators, but it doesn't.

Could you give a help please?

Thanks

I've been reading:

But I'm not getting things clear.

We have two scenarios, when we by materials for the projects and when we by materials to sale them. We don't usually have stock so we normally generated PReq tu buy it. But if we do have stock we want to generated a reservation for the project.

We are using Procurement Type X and Special Procurement 20 (as we want to have PReq generated by the MRP and not reservations).

But when we add components to a project through CN33 and we use item category in L in the BOM we would like a reservation to be generated. Is that possible? Or is a nonsenses?

Thanks
