Formulas within Master Recipe

Hi all,

I am currently looking into Formulas and Master Recipes,

Using transaction C203 you can see the BOM with its associated values that make up the recipe. You can also look at any formulas associated with the material and its BOM.

I know the BOM is held in tables STPO and the formulas are held in table KALC.

What I cant seem to figure out is how the Materials on the BOM are linked to the materials on the Formula screen as in some instances I've seen the order can be different between the two.

Also I'm have been trying to figure out what KALC-ROW_ID is made up of, I think this is key to mapping between the two but cant seem to find any related help.

Any Help much appreciated.

Hiten.
