## Max by group by not working

Hi All,

Please can I know why my max by group by is not working?

I reffered to various threads in here and they have done the same , but doesn't work for me.

I need to find the maximum of 'Changed date' by employee, but it returns the maxium for the table.

You are using on the same table that is causing an issue. Ref -https://docs.microsoft.com/en-us/dax/allexcept-function-dax

Try using employee from the employee dim

## Re: Max by group by not working

Hi,

I am a newbie to power BI and DAX,  couldn't understand where the test107measure column/measure came from in the formula  ?

`Test107 = CALCULATE(SUM(Test107Measure[Sales]),FILTER(ALL(Test107Measure),Test107Measure[Client]=SELECTEDVALUE(Test107Measure[Client]))) `

## Re: Max by group by not working

Should be something like this in your case

`Max Employee = CALCULATE(max(sheet1[change Date]),FILTER(ALL(sheet1),sheet1[employee]=SELECTEDVALUE(sheet1[employee]))) `

So it might work as a measure
