Hi Sean,
there's no concatenate function as of 7.4 SP5.
A workaround in OpenSQL (if that's the combination you use), you could use the columns of your choice in the projection list like (I use literals in the example for simplicity):
{
'a'as a,
'b'as b
}
and concatenate later by means of OpenSQL:
select a&& b from <cds_view> into ….
However, if you want to use the view in an ALV this does not help you, I know…
Cheers,
Jasmin
