Answer / eldho

We can do it in 2 ways.
In rdf, we can define a summary column (say
CF_COUNT)which counts the number of rows of a group, and in
the rtf layout create a text form field and put the help
text as <?if:CF_COUNT=0?>No Data Found<?end if?>
Other way, no need of summary column, in the rtf layout
create a text form field and put the help text as
<?if:
count(./LIST_G_SO_NUMBER/G_SO_NUMBER/LIST_G_SO_NUMBER1/G_SO_NUMBER1)=0?>No
Data Found<?end if?>

where
./LIST_G_SO_NUMBER/G_SO_NUMBER/LIST_G_SO_NUMBER1/G_SO_NUMBER1
is the expected path to the group, from the root of the xml,
that we define. This expression will count the number of
occurances of the group "G_SO_NUMBER1"
