displayLookup

Procedure that finds and displays a Lookup. This routine is published by the SmartViewer to populate the Lookup with the evaluated query data, if the query was successful. The queries were initially built in getLookupQuery.

Location: lookup.p

Parameters:

INPUT TABLE FOR ttLookup Notes: None

This allows all lookup queries to be built at the cost of a single AppServer call.
Note that this is not run at all in ADD mode, unless the Lookup is manually fired.
