@Satish_Kumar,

 

Please create the measure as a Calculated column with the same formula. Wherever we use calculated measure, it will return a single value. It expects aggregation function to return a value.

 

Thanks,

Siva

@SivaMani

 

Thanks for replying.....

 

You want to me recreate the same column as a measure.

But why it shows me an error I did the same to lookup my Lastfy and it was done successfully.

Is it a calculated measure or column?

@SivaMani

 

Actually, i am not able to create last month as a measure.

And as you told me to do I tried but I think we cannot use the same formula to create the measure.

If I am wrong then please correct me.

Satish 

 

@Satish_Kumar,

 

You requirement is,

Last Month.PNG

Right?

@SivaMani

 

Yes!!!!

 

But I have to make a lookup with another table also to demonstrate their values according to years and month.

Use the Last Month DAX which you created earlier,

 

LM = LOOKUPVALUE(Testing[MonthName],Testing[MonthOrder],Testing[MonthOrder]-1)

 

It will work

@SivaMani

 

Sorry!!

 

But it is not working.

Create calculated column instead of measure.
