Avererage in column with variant data type

Hi all,

I am stuck in the matrix table in PowerBI.

See data below.

Column VALUE is formatted as numbers, TEXT as text and U_RPT_VALUE also as text.

TEST_NUMBERNAMEVALUETEXTU_RPT_VALUE
721195Component 10.10.1< 0.2
721178Component 100.0< 0.2
721188Component 24.334.334.33
721183Component 300.00< 5.9
721182Component 300.00< 5.9
721181Component 30.560.56< 5.9
721192Component 40DoneDone
721198Component 5755755755
721199Component 5730730730

Now I want to have a matrix table with the average of each component.

The problem is that because the column contains data and text you can only choose count, first etc

This will give the incorrect data for Component 5. 

 

So I created Measure = AVERAGE(Sheet2[VALUE]) but that will show incorrect values for component 3

I'm trying to build someting like:  If(U_RPT_VALUE contains < then show U_RPT_VALUE else (Measure = AVERAGE(Sheet2[VALUE]))

However, I cannot get it working due to the different data formats.

 

Do I make it myself to complicated and is there an easy way to accomplish this?

Thanks for the support!

Sander

Hi @SanderB 

 

Try the below

Measure = 
VAR _text = SELECTEDVALUE( 'Table'[U_RPT_VALUE] )
VAR _search = SEARCH( "<", _text, 1, 0 ) > 0
RETURN IF( _search, _text, AVERAGE( 'Table'[VALUE] ) )

Try the below

 Hi @Mariusz ,

 

Thank you very much, the use of a measure like that is totally new for me 🙂

It works perfect in the example, but on the complete database I get the "Expressions that yield variant data type" error. 

This is caused by the Table[U_RPT_VALUE]

There is a lot of data in this table, dates, <,>,negative numbers,-, text and empty

 

Is there a way make this usefull? Otherwise I can create a new column and filter all the stuff out and see if it works

 

It works! Corrected the column and it is perfect!

Thank you very much!

Hi @Mariusz ,

 

Only one small question about AVERAGE.

Is it possible to have the decimal places dynamic?

I thought that the FIXED function will do this, but this does not work.

 

Measure = 
VAR _text = SELECTEDVALUE( RESULT[Merged] )
VAR _search = SEARCH( "<", _text, 1, 0 ) > 0
RETURN IF( _search, _text, FIXED(AVERAGE(RESULT[VALUE]),(RESULT[PLACES]),1))

Thanks,

Sander 

 

HI @SanderB 

 

You need some form of aggregation around RESULT[PLACES], try MIN or MAX like below.

 

Measure = 
VAR _text = SELECTEDVALUE( RESULT[Merged] )
VAR _search = SEARCH( "<", _text, 1, 0 ) > 0
RETURN IF( _search, _text, FIXED( AVERAGE( RESULT[VALUE] ), MAX( RESULT[PLACES] ), 1 ) )

Hi @Mariusz,

I looks like the FIXED function does not work there.

It will only give zero's and the filters are not working anymore, even without dynamic reference.

FIXED(AVERAGE( RESULT[VALUE] ),4,1 ))
 

Hi @SanderB 

 

Can you give an example?

Measure that is working with the incorrect decimals:

Measure = 
VAR _text = SELECTEDVALUE( RESULT[Merged] )
VAR _search = SEARCH( "<", _text, 1, 0 ) > 0
RETURN IF( _search, _text, AVERAGE( RESULT[VALUE] ))

Measure that is not working:

Measure = 
VAR _text = SELECTEDVALUE( RESULT[Merged] )
VAR _search = SEARCH( "<", _text, 1, 0 ) > 0
RETURN IF( _search, _text, FIXED( AVERAGE( RESULT[VALUE] ), MAX( RESULT[PLACES] ), 1 ) )
