Mutiple products mfg by same recipe

Hello ,

I have 4 different products which are made on same m/c .I created a common recipe group for it.

The bill of material will be different for all the same , only mfg m/c and time will be same.

Do i need to create a different recipe for each products or can work with same recipe group.

The bom for all the materials will be different .

How do i create the recipe ?
