Restrict value of one variable corresponding to value passed in other.
I have query regarding BEx Authorization for the given selection screen of any variable for any report :
I have three parameters/variables( Circle ,SSA and Exchange) which needs to be passed from User. Circle(state)->SSA(City)->Exchange(Sub Locality). I want to restrict the value of second and third variable corresponding to the values passed in first variable. For e.g. : if a value Madhya Pradesh is passed as a Circle then SSA selection screen should show only
City or SSAs of Madhya Pradesh only. Same case with selection screen of exchange variable also.
