When the vp_ddate variable appears in the Locals window, what is its value? After the value is set in the business object's Requery method, continue to step through into the data behavior object's Requery method. Make sure the vp_ddate variable is visible and has the correct value right when the actual Requery() is issued. Also, check the currently selected ALIAS() in the Watch window.

If the View Parameter window doesn't appear when USEing the view manually, it should also work inside of the business object. At the point where the Requery() is physically issued, it's a simple matter of "does the vp_ddate variable exist?". If it doesn't, then the view parameter window will be displayed.

Regards,
