Data drill down a table

Hi sushdutta 

Please try this:

Table:

First of all, create a calculated table:

Table 2 = SUMMARIZE('Table','Table'[Acc],'Table'[Customer])

Create a Slicer with 'Table2'[Customer]:

Then add a measure:

MEASURE =
VAR _vtable =
    SELECTCOLUMNS (
        FILTER (
            CROSSJOIN ( 'Table 2', ALLSELECTED ( 'Table' ) ),
            'Table 2'[Acc] = 'Table'[Acc]
        ),
        'Table'[Customer]
    )
RETURN
    IF ( MAX ( 'Table'[Customer] ) IN _vtable, 1 )

The result is as follow:
