How to Create Measure for Count by Condition

HI Noppadon,

Currently, Dax formulas not able to respond with common language condition strings.
I think you need to wire measure formulas with switch function and trace current case, then you can write multiple expressions for different case calculate.

Measure =
VAR currCase =
    SELECTEDVALUE ( Table[Case] )
RETURN
    SWITCH (
        currCase,
        "All Size Quantity in Item as 0", 'expression 1',
        "Some Size Quantity in Item less than or equal 0", 'expression 2',
        "All Size Quantity in Item Quantity > 0", 'expression 3',
        'default process'
    )

Write Conditional Statement Using SWITCH in DAX and Power BI
