>You can define a Local View (I hate them :o) or Cursor Adapter and put some input parameters into select clause. Then Base the Grid on that View/CA. When the user selects day and Work Center just add these values to parameters and refresh the view/CA.

The user doesn't want to select a day/work center. They want to basicly see 7 days and mutliple workcenters all at the same time. So it would almost be like an excel document that in side the cell contained another excel document.
