Store NameDevice Usages
Store 1KP 113
Store 1 KP 218
Store 1KP 315
Store 2 SD 11
Store 2SD 2 32
Store 2SD 314

 

Expected outcome : 

 

Rank 1 : KP 2 

Rank 2 : KP 3 

Rank 3 : KP 1

 

Essentially i just want the ability to filter devices that start with KP from a list of Devices and Rank these based on usages.

    JamesBurke So like this?

    Rank = RANKX( FILTER( ALL('Table'), LEFT([Device],2) = "KP" ), CALCULATE(SUM([Usages])),, DESC )

      Rank = 
      RANKX(
      FILTER( ALL('Emporia Devices'),
      LEFT('Emporia Devices'[Device Name],2) = "KP" ),
      CALCULATE(SUM('Emporia Device Usage'[Usages KWH])),, DESC )
       
      This does not filter the device names to only rank KP Stores, it ranks all and not by Usages for some reason.

        JamesBurke How about this?

        Rank = 
IF( LEFT('Emporia Devices'[Device Name],2) = "KP",
RANKX(
FILTER( ALL('Emporia Devices'),
LEFT('Emporia Devices'[Device Name],2) = "KP" ),
CALCULATE(SUM('Emporia Device Usage'[Usages KWH])),, DESC ),
BLANK()
)
