Create formula

Hi;

There are number of Items (Ingredients) created in inventory Organization with some differnce in their specification of quality, City and Supplier and all these items are used to produce a product for exmaple P1. When we make a formula to produce product P1 than we have to make different  formual on the basis of Ingredients. In this case number of formulas are increasing. Infact all these Ingredients are same but due to maintain inventory separately on the basis of quality, City and Supplier different items are created.

Now we are facing challenges to make multiple formula as inventory item is different. Is there any option or suggestion so that we can make a common formula to produce product P1. And at the consuming Ingredients we consume actual inventory item (Ingredients). Please advice.
