Assigning the value sets dynamically based on parameter values

Hello,

I am having a custom Concurrent program with 2 parameters

 

Sequence –

Name

 

The parameter ‘Sequence’ has a value set which is a static list containing 2 values ‘BEFORE’ and ‘AFTER’.

My requirement here is if you select ‘BEFORE’ in the first parameter, the second parameter should show me list of values A through D.

If I select “AFTER” in the first parameter, the second parameter should show me list of values M through Z.

 

IF parameter1 (sequence)= “BEFORE” THEN

   Parameter2 (name) should show value set where user can pick a value between A through D

IF parameter1 (sequence) = “AFTER” THEN

  Parameter2 (name) should show value set where user can pick a value between M through Z.
