The simple meaning of a stage variable is just like a
global variable.During processing the execution starts with
stage variables then contraints and then to individual
columns.If ever there is a prerequsite formulae which can
be used by both contraints and also individual columns then
we can define it in stage varaibles so that it can be
processed once and can be used by multiple records.If ever
we require the formulae to be modified for each and every
row then it is advisable to place in code in record level
than stage variable level
