## Aggregation Function?

I'm trying to create the table above. Group and Item are dimensions. % is a measure calculated as the average value of binary column at the item level. How can I create the Max% column where it shows the maximum % of each Group?

I feel like it should be an aggregation function, but i'm really struggling to get anything to work. Any help would be greatly appreciated!

## Re: Aggregation Function?

use this expression in a straight table with your dimensions:

=aggr(NODISTINCT max(%),Group)

## Re: Aggregation Function?

The challenge is that % isn't the lowest level of aggregation. The % is calculated as Avg(% Flag).

% Flag is a column made up of 1 and 0 values.

I'm trying =aggr(NODISTINCT max(Avg([% Flag])),Group) but it's just returning null values.

## Re: Aggregation Function?

Then If you are using % as expression before calculating MAX, then you can use the column name instead of formula and check.

Example:
=aggr(NODISTINCT max(column(1)),Group)
