Adomas,

Will can branch the execution inside the SP (to do not calculate what is
not necessary) if you pass an inout parameter saying what parameters you
will need.

you could use a Bitmap integer to represent the parameters you will
need, there is and UDF that performs bitwise operations.

see you !
