Hi All ,
Please explain this expression :
Only({1}(Match(Country,'USA','UK','BR','IN','AG')))
What is the significance of only to this expression ?
Regards
Shekar
The explicite use of the only function allows to add a set expression, which may help in ignoring user selections:
User selected Georgia. See the difference?
Only() converts an ordinary function call returning a single value into an aggregation expression (example for use in chart expressions where Only() is often implied.)
Highly context-dependent. Where is it used?
Hi Peter
Thanks for reply .
It was used for custom sorting of a Multibox to ensure that on user selection position of field value does not change .. Now can you help me understand , how it works .
I guess the main reason for usage is to allow the application of set analysis (which you can only use in combination with an aggregation function like Sum(), Count() .... or Only() ! )
I am attaching sample qvw .
Please explain only() in that context .

I got it now ... Only() for Demystified to me ..
Thank You Stefan ..
