Sub Queries using Add Command

Hello All,

I have been asked us to develop crystal reports Using Add Command. We have 2 main queries and 2 sub Queries for Condition\Filter.

Is it possible to use 2 commands (One for each main Query) ? Once we add these two main queries using Add command option

but still we need to work on the joins i believe then when can I pass sub queries?

Can someone explain the scenario. I am not aware of this method.

Best Regards

Sandeep
