This is the initial height for the instance list (in pixels) for VLF-ONE business objects.
It is used only the first time the user ever opens the business object. Thereafter the sizing that the user adjusted the panel to is always remembered (even between sessions) so this property is not used, unless the user clears the browser cache and restarts.
If a filter is displayed at the LEFT or RIGHT of the instance list, and the filter's designed height is higher than the instance list initial height, then the filter's height will be used to size the initial panel height.
This property is in the Business Object Instance List tab.
