Why don't you create the new field in the script?
LOAD * INLINE [
SIM Card, 10
if(Mixmatch(Name,'CellPhone','Cellphone Charger','SIM Card'),'Cell Phone',
,'Others')) as Category
And now you can use Category as a dimension instead of using the If(MixMatch(...)
Thanks for your quickly response .
to create a new filed in LOAD Scripts is a great workaround for this issue,
but I am looking forward a new way for users to create group when they create their own dimensions.
For Instance, By Age group ,some users use 10 years age group, some might use 5 years age group ,or someone else will use under 17 as Juvenile, and for those older than 17 will use 5 years age group.
