Many Manufactures use this parameter as it was intended to indicate if the fitting with the specified dimentions exist in their catalogue or not. It's stupid that they then have to add an aditional custom shared parameter to replicate the same behaviour (or the oposite) just so we can schedule and/or filter...
We end up with dozens of equal shared parameters when we have a great one already in the program. Please revise this so we and the manufactures can make better and ligher families.
PS: while you are at it, expose all other still missing parameters too - there is a bunch of wish list ideas just like this one for many other OOTB parameters.
