Hi - probably a very silly question, but how do i access some properties/collections which aren't in the properties dialog of a particular task? For example, I would like to pass as parameters columns mappings for a table (Destination Data Flow component), not do it through the graphics. For the migration excercise i would like to have 1 source data flow component and 1 destination data flow component and i pass in from a parent package the tablename, mappings, conversions etc. Surely this is a decent way of doing the migration? Or is this overkill? Anyway - getting back to the point, I can't see any of the required properties - e.g. available input cols, available dest cols etc. Or are they not properties?! Thanks in advance...! Cheers, Jon
