Select rows with largest value by one dimension

[lzzoe]

Hi All,

I am quite new to Qlik. I want to select rows with largest NUM in each ID_NO. I want to do this in chart preparation stage instead of data loading stage. I try to use "= Max(TOTAL <ID_NO> NUM)" but it does not work. Thank you

Current:

ID_NO	OTHER	NUM
112233	AB	5
112233	AB	7
112234	AB	1
112235	CF	8
112235	RG	10
112235	DG	7
112236	RY	6
112236	WA	8

To-be:

ID_NO	OTHER	NUM
112233	AB	7
112234	AB	1
112235	RG	10
112236	WA	8

Try this 
AGGR(MAX(NUM),ID_NO)

Hi Nagaraju,

may I ask where I should type this expression in?
