One BOM with three resources in SAP PP-PI

Dear All,

We have one scenario that we have a one finish material BOM and there are three resources.

So how to we map in system so this is convenient and easy for ens users.

BOM A for finish material B and its produce from resource 1,2 and 3.

then how we can do in system.

According to me .

BOM A + Recipe 1 with resource 1 =PV01

BOM A + Recipe 2 with resource 2 =PV02

BOM A + Recipe 3 with resource 3 =PV03

but is complex for users when they create process order and do confirmation then they Confuse to select the process order.

Please suggest me ASAP.

Regards

Mahendra
