Nilesh,
The External is used exactly like a static qualification is used, except
it's dynamic....if you had

'Field1' = "This" AND 'Field2' = "That"

but if you instead wanted it to be dynamic, in the qualification you would
put

EXTERNAL($zTmpField$)

and in zTmpField you would populate the string

'Field1' = "This" AND 'Field2' = "That"

it's as simple as that.
