## Calculating average of summed values

Hi everyone,

I have a table regarding the sales of our sales reps. that has the following structure:

 Sales Rep Year Month Sales Value A 2020 5 5 € B 2020 6 10 € B 2021 6 11 € … … … …

I would like to create an average growth of each sales rep so I can say something like "Sales rep E's sales grew by 8% while on average the sales of sales reps A-D grew by 4%".

My initial idea was to use the SUMMARIZE command to create a table like this:

 Sales Rep Sales Value CY Sales Value PY Growth A 465 € 320 € 45% B 650 € 544 € 19% … … … …

...from which I was hoping to use the AVERAGE command to calculate the desired value. However, I am uncertain how to actually build a table like this with SUMMARIZE.

Can anyone please help? Or do I even overcomplicate the issue and a simpler DAX approach is possible here?

--------

Here is my current DAX attempt (where I am having difficulties including the growth column):

``````TEST =

SUMMARIZE(
Table,
Table[Sales Rep]
),
"CY",
CALCULATE(
sum(Table[Sales Value]),
FILTER(
'Date',
year('Date'[Date]) = 2022
)
),
"PY",
CALCULATE(
sum(Table[Sales Value]),
FILTER(
'Date',
year('Date'[Date]) = 2021
)
)
)``````

@ThomasSan This looks like a measure aggregation problem. See my blog article about that here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149

The pattern is:
MinScoreMeasure = MINX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
MaxScoreMeasure = MAXX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
AvgScoreMeasure = AVERAGEX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
etc.
