Please any one can help me to convert this below code into Setanalysis
if( not isnull([Platform]),[ flag] &[Id] ))
Note:- [ flag] &[Id] - Due to this am getting allocated memory exceeded in the chart in QlikView 11
So am thinking that set analysis can help this out.
I think I'd create a new field based on [ flag] & [Id] in the script. Is that doable?
That could be the last option..
I would almost always try and push as much logic into the script as possible. Saves on server resources in expressions etc (unless you are creating lots of superfluous data of course!)
Have you tried
If(([Platform]<>NULL),[ flag] &[Id] ).
Retrieving data ...
