Isolate Manufacturing items PO from R&D items PO to the same supplier

Hi All,

I have a business requirement where in we would like to segregate the PO for same item (Eg: Item A) to the same supplier but one for Manufacturing and another for R&D. This way we can segregate them when running our ASCP plan. The planning engine should only be using the PO which is required for Manufacturing and not the PO which R&D has raised.

I am thinking which is similar to using different order types in Sales order. Its possible to select what sales order types are included in ASCP plan.

If there is any other way how to segregate the demand of R&D from Manufacturing that is also welcome.
