How to use multi-level BoM to create planning proposal in SAP Bydesign?

Hi, Experts:

I created a multi-level BOM as following.

And I want to create a planing proposal (or production requests) which BOM is expand to end-level,

e.g: the input products are P100201, P100436, P100001, and the output is P100301

But I just could create a planing proposal which input products are P1000201 and P100505 as following.

If have any set up or solution to create production proposal with multi-BOM?

Best Regards,

Mola
