Lets say, we have three parameters A, B and C. B is dependent on A, C is dependent on A and B. If A value is entered, then we can list only the values of B which are related to A. If User is not entered A value then how can we list all values available in B? In the sameway for C also ( If A and B values not entered then it should allow to select a value from all available values in C)?
I don't want to put default "ALL" value and then use this in other value sets to get all values. Is there any other way using some dummy parameters? I searched in threads but couldn't find relevant.
