Hi Guys,

I have a requirement to show the report title in two lines based on the Input Selection screen .

title would be:                     text of WBS element

                                      progress report   start date  and enddate.

End date and Start date are too input selection  on the bex query.  Please let me know can we do this is BEX Query designer or need to develop in Workbook.

Thanks in advance.
