在为 power bi 中的标志列创建计算列或度量时需要帮助

Question

I need help in Creating a Flag column based on the aggregated values of two columns in power bi, similar to group by in sql and Fixed{Columnname:Value} in tableau.

Amount_rc, Amount_rb are two numeric columns

Flag Condition:

Flag = 
IF(
    'Table'[rc]<>0 && 'Table'[rb]<>0,
    "rc nd rb",
    IF(
        'Table'[rc]<>0 && 'Table'[rb]=0,
        "rc not rb",
        "rb not rc"
    ) 
)

The above calculation is working at each record level. I want it to work at summarized level as below

Answer 1

Make a measure (not a calculated column) and wrap the columns with a SUM or MAX aggregate:

Flag = IF(SUM('Table'[rc])<>0 && SUM('Table'[rb])<>0,
    "rc nd rb",
    IF(SUM('Table'[rc])<>0 && SUM('Table'[rb])=0,
        "rc not rb",
        "rb not rc"))

(probably rc column should be rv , considering your screenshot)

Answer 2

I think you need 3 separate Measure to achieve your required output.

Measure-1

rc_new = SUM('Table'[rc])

Measure-2

rb_new = SUM('Table'[rb])

Measure-3

Flag = 
IF(
    rc_new <> 0 && rb_new <> 0,
    "rc nd rb",
    IF(
        rc_new <> 0 && rb_new = 0,
        "rc not rb",
        "rb not rc"
    ) 
)

Now add them to the table visual instead of adding rc and rb column directly.
