Need Suggestion on the following scenario in a standard cost environemnt

Hi All,

Please suggest me the best suitable option:

Manufacturing Process involves botanical solvent extraction.

Now in the facility , we have 3 different extraction lines with different capacity, through put and nominal cost.

Standard cost will be derived based on any one of these lines, which we select as costing recipe.

Now , for manufactuing, is it good to have 3 different routes and recipies or 1 recipe and in production batch user will go and update the actual resource and its usage dynamically?

Please suggets.

thanks

Abhik
