How to choose the record with the highest value by group

[Anonymous]

Hi everybody,

I would like to ask, how to choose the last record in table. I have table with many rows. I would like to recognize and choose only rows, where the value is the highest.

Example:

ID | Group name | Value

0 | All | 0

1 | Woman | 1

2 | Man | 1

3 | Woman's T-shirt | 2

4 | Woman's shoes | 2

5 | Woman's socks | 2

The result is:

3 | Woman's T-shirt | 2

4 | Woman's shoes | 2

5 | Woman's socks | 2

AND

2 | Man | 1

because group Man doesn' t have higher value in column Value.

Do you know, how to do it? In real life it looks like tree, where you have groups and sub-groups. And you know ID employee (column ID) and you know his manager (because you have other columns as Manager, where is ID employee). So there is know superior and subordinate relationship.

I tried filter values by highest value, but I lost group Man with value 1. I tried change table from star to snowflake.

Do you have any ideas, how to solve it?

Thank you very much for help.

Mary

Hi @Anonymous ,

Please check the following step as below.

1. Create two calcualted columns in the fact table.

new group = 
IF (
    'Table'[Value] = 0,
    BLANK (),
    IF ( SEARCH ( "Woman", [Group name],, BLANK () ) = BLANK (), "man", "woman" )
)

max value = 
CALCULATE (
    MAX ( 'Table'[Value] ),
    FILTER ( 'Table', 'Table'[new group] = EARLIER ( 'Table'[new group] ) )
)

2. Create a calculated table to get the excepted result.

Table 2 = 
SUMMARIZE (
    FILTER (
        'Table',
        'Table'[new group] <> BLANK ()
            && 'Table'[Value] = 'Table'[max value]
    ),
    'Table'[ID],
    'Table'[new group],
    "value", MAX ( 'Table'[Value] )
)
