Finding unique / distinct values from a row

I have a table like this  : I wanted to know the number of storage connected to VM ( Datastore name contains the storage name )

Server NameDatastores.1.1Datastores.2.1Datastores.3.1Datastores.4.1Datastores.5.1Datastores.6.1Datastores.7.1Datastores.8.1
VM1PureStorage05PureStorage05PureStorage05PureStorage02PureStorage02PureStorage02PureStorage05PureStorage05
VM2PureStorage05PureStorage02PureStorage05PureStorage05PureStorage05PureStorage05PureStorage02PureStorage02
VM3InfiniStorage09PureStorage06PureStorage06PureStorage06PureStorage01PureStorage01PureStorage06PureStorage06

 

 

I am looking for an output like this  :

Server_NameNo_of_Storage_connected StorageArray
VM12PureStorage05 ,PureStorage02
VM22PureStorage05 ,PureStorage02
VM33InfiniStorage09,PureStorage06,PureStorage01

 

 

Could you please help me to find a way to do this  ?

@Saul_K tweak the measure to filter out N/A:

 

Storage Count = 
VAR __Table = 
DISTINCT ( 
    UNION ( 
        VALUES ( 'Storage'[Datastores.1.1] ),
        VALUES ( 'Storage'[Datastores.2.1] ),
        VALUES ( 'Storage'[Datastores.3.1] ),
        VALUES ( 'Storage'[Datastores.4.1] ),
        VALUES ( 'Storage'[Datastores.5.1] ),
        VALUES ( 'Storage'[Datastores.6.1] ),
        VALUES ( 'Storage'[Datastores.7.1] ),
        VALUES ( 'Storage'[Datastores.8.1] )
    )
)
RETURN
COUNTROWS ( FILTER ( __Table, [Datastores.1.1] <> "N/A" ) )


Storage Array = 
VAR __Table = 
DISTINCT ( 
    UNION ( 
        VALUES ( 'Storage'[Datastores.1.1] ),
        VALUES ( 'Storage'[Datastores.2.1] ),
        VALUES ( 'Storage'[Datastores.3.1] ),
        VALUES ( 'Storage'[Datastores.4.1] ),
        VALUES ( 'Storage'[Datastores.5.1] ),
        VALUES ( 'Storage'[Datastores.6.1] ),
        VALUES ( 'Storage'[Datastores.7.1] ),
        VALUES ( 'Storage'[Datastores.8.1] )
    )
)
RETURN
CONCATENATEX ( FILTER ( __Table, [Datastores.1.1] <> "N/A" ), [Datastores.1.1], "," )

Isn't it enough simple after you unpivot the table?

ThxAlot_0-1693655994237.png



Expertise = List.Accumulate(


        {Days as from Today},


        {Skills and Knowledge},


        (Current, Everyday) => Current & Day.LeanAndPractise(Everyday)


)



Thanks for the response.  I am very new to Powerbi and not good with the unpivot option, I will take a look. Thank you for the suggetion.

@Saul_K Usually you want unpivoted data but with the current structure, you can add the following two measures to get the result;

 

Storage Count = 
VAR __Table = 
DISTINCT ( 
    UNION ( 
        VALUES ( 'Storage'[Datastores.1.1] ),
        VALUES ( 'Storage'[Datastores.2.1] ),
        VALUES ( 'Storage'[Datastores.3.1] ),
        VALUES ( 'Storage'[Datastores.4.1] ),
        VALUES ( 'Storage'[Datastores.5.1] ),
        VALUES ( 'Storage'[Datastores.6.1] ),
        VALUES ( 'Storage'[Datastores.7.1] ),
        VALUES ( 'Storage'[Datastores.8.1] )
    )
)
RETURN
COUNTROWS ( __Table )


Storage Array = 
VAR __Table = 
DISTINCT ( 
    UNION ( 
        VALUES ( 'Storage'[Datastores.1.1] ),
        VALUES ( 'Storage'[Datastores.2.1] ),
        VALUES ( 'Storage'[Datastores.3.1] ),
        VALUES ( 'Storage'[Datastores.4.1] ),
        VALUES ( 'Storage'[Datastores.5.1] ),
        VALUES ( 'Storage'[Datastores.6.1] ),
        VALUES ( 'Storage'[Datastores.7.1] ),
        VALUES ( 'Storage'[Datastores.8.1] )
    )
)
RETURN
CONCATENATEX ( __Table, [Datastores.1.1], "," )

Thanks a lot , that helps . I am very new to power bi and my questions may feel silly 🙂  I have one more ask,how we can ignore 'Null' / 'N/A' values when you run the above query ? I had null values before, but I changed  it to N/A. 

 

The below is the sample table. 

 

Saul_K_0-1693833050347.png

 

As there is N/A value in most of the row, it calculate that as a value and add it in to count and storage array output.

 

 

Server_NameNo_of_Storage_connected StorageArray
VM12PureStorage05 ,PureStorage02
VM23PureStorage05 ,PureStorage02,N/A
VM34InfiniStorage09,PureStorage06,PureStorage01,N/A
