Variable mass UOM for parameters
Some non-mass measures, like cup or package, do not account for the mass of various items or forms of an item. For example, the mass of one cup of shredded carrots is different than for one cup of sugar or one cup of sliced carrots. One standard relationship between mass and cup does not apply in all cases.
count UOM type,
         but you must use a mass equivalent  to process weight-based rollups such as nutrition:- 4 jumbo shrimp per salad
 - 4 small shrimp as garnish
 - 1 slice of cheese per sandwich
 - 1 8oz can of tomato sauce
 
You can create parameters with the Parameter
            Type
         type 9 UOM Conversion Factor and type 16 Variable
            UOM to process weight-based rollups.
See Creating the parameter for more information on creating parameters for weight-based rollups.
See Variable mass units of measure for more information on variable UOMs.
