A Single Value for Column Cannot Be Determined

[CNYUser]

Good Day,

I'm using this to try and create cohorts using Version: 2.121.644.0 64-bit (September 2023) Desktop

Site Last Touched Days Cohort = IF('Account Summary - TC'[Last Touched Days Site] <= 30, "A:30 Days", IF('Account Summary - TC'[Last Touched Days Site] <= 90, "B:90 Days", IF('Account Summary - TC'[Last Touched Days Site] <= 180, "C:180 Days", IF('Account Summary - TC'[Last Touched Days Site] <= 365, "D:365 Days", "E:Over 365 Days") ) ) )

I'm getting A single value for column 'LAST_TOUCH_DATE' in table 'Account Summary - TC' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

The data type is a whole number; format as whole number and summarization is Sum.

Any ideas on how to correct?

Thank you so much!   that worked 🙂

@CNYUser In a measure, you need to wrap any column reference in an aggregator like MAX, MIN, SUM, etc. Also, I would switch to using a SWITCH(TRUE(), ...) statement instead of nested ifs but that's not the issue with your formula.
