same scope of check/check control for ECC & gATP?

Hi Experts,

Say for example I have 100 products in ECC. 50 products I want to do availability check in gATP & remaining 50 material I would like to do availability check in ECC itself. To differentiate the material between ECC and APO I have maintained MRP type 'PD' in MM for the products which need to do the availability check in ECC and 'X0' maintained for the products which need to do the availability check in gATP.

The question arises - Can I use the only one Scope of check  (check control in APO)/Availability check in MM for the both the PD (products which need to do availability check in ECC), X0 - product which need to do availability check in gATP.

say for example -

for some product availability check 01 which need to check availability in ECC and gATP

for some product availability check 02 which need to check availability in ECC and gATP.

Can I use above check control/scope of check for the products which need to do availability check in ECC and as well in gATP. But MRP types are different to each other. PD is referrers to ECC material and X0 referrers to APO material.

Thanks,..
