The parameter needs to be set as a variable visible during the evaluation of the SQL statement of the view - IOW, a private variable to the piece of code from which you call requery() of your view.

The filter in your case didn't work because of the order of instantiation - the dataenvironment is created before any other objects (as they may be bound to its tables/fields), so it's just too early, the form (which is instantiated) last doesn't exist yet. You may filter it later - but still, doing a view is much better:

vp_parameter=thisform.accnt
requery("myviewalias")
