Regarding help for power BI DAX

Hi Emranit 

You can use a measure to virtually summarize a table then multiple  virtual capacity column by 2.5, assuming there's only capacity value per day per machine. 

Machine Capacity =
SUMX (
    ADDCOLUMNS (
        SUMMARIZE ( 'Table', 'Table'[Date], 'Table'[Machine Name], 'Table'[Capacity] ),
        "@machine capacity", [Capacity] * 2.5
    ),
    [@machine capacity]
)

Otherwise you'll need to calculate the max capacity per machine per day virtual before multiplying it by 2.5

Machine Capacity2 =
SUMX (
    // Iterate over each unique Date–Machine combination
    ADDCOLUMNS (
        SUMMARIZE ( 'Table', 'Table'[Date], 'Table'[Machine Name] ),
        
        // Add a computed column for capacity × 2.5
        // CALCULATE is needed so MAX('Table'[Capacity]) is evaluated
        // in the filter context of each Date–Machine row produced by SUMMARIZE.
        "@machine capacity",
            CALCULATE( MAX( 'Table'[Capacity] ) ) * 2.5
    ),

    // Sum all values of the computed column
    [@machine capacity]
)
