The filter is applied next time you change to one of the RFC views. It stays in effect until you change it.
If you set the filter before logging on, then the data downloaded and displayed initially is filtered accordingly.
However, if you change the filter after connecting and after the data is already displayed in one of the RFC views, then you must refresh the view or
change the filter.To refresh the view with the new filter, choose either ViewàRFC àFunctions or ViewàRFC àFunction Groups.
The filter that is in effect is shown at the top of the hierarchy in the RFC tab.
