Multiple Vendor for interchangeable Spare

Hi Experts,

Could you please help me to provide solution for below scenario related to SAP PM & MM.

I have 1 Valve and this valve we can purchase from three different vendors.The question is:

1. Shall we create 3 different MM code.Which is confusing for end users and also to difficult to maintain Min-Max Level.

2. If we create one MM Code then how we maintain three vendor for one MM Code and how while PO creation procurement team will decided from which vendor this material to be purchased.

Appreciate your expert advise.

Thanks,

Kavvya.
