How to set an alternate item inside a formula in AX ? [*-)]

What does it mean? Can u eloberate?

I, too, have the same question. Within a formula, I should be able to use my alternate function identified in the item set up. However, when setting up backflush properties, I have difficulty getting the results needed to switch from a depleted item to the alternate. How is an alternate identified in the formula lines, please?

What do u mean by “alternative” are you trying to assign an alternative substitute in case of scarcity of ingridiants of formula?
