1.i have a dataenviroment with the connection set.
2.1 command added with the required query.. This is the parent command.
3. I Add a child command to the parent command.Set the query and the relation with the parent.

eg.
data enviroment.
connection
command1.
command2

this is the heirarchy..

Now @ run time
i want to change the query for the command 1 and want the relevant data from command2.
Thus display records on my report.
