Assign materials to particular Asset Number

Hello Experts,

I wanted to restrict the materials showing in the workorder as per the Asset Number. Otherwise, i need to assign X number of maintenance spares to a particular Asset Number(as one time setup like BOM) and if this Asset Number is used in work order then it should show only assigned Materials. I tried Copy from BOM option but still need a best and efficient way to offer to my client.

Kindly put your thought point on this and help.

Thanks..
