Not displaying the sub levels if only one sub level in Matrix visual

Hi Arshadjehan ,

Sorry for misunderstanding your request. Here we cannot filter the matrix directly, we can create measure to work on it.

sum of be = 
VAR dis =
    DISTINCTCOUNT ( 'Table'[sub2] )
var be = SUM('Table'[BE])
var a = IF(dis = 1
            && ISINSCOPE ( 'Table'[sub2] )
            && OR (
                SUM ( 'Table'[Release] )
                    = CALCULATE ( SUM ( 'Table'[Release] ), ALL ( 'Table'[sub2] ) ),
                SUM ( 'Table'[Release] ) = 0),TRUE())
var  b = 
IF(dis = 1
            && ISINSCOPE ( 'Table'[sub2] )
            && OR (
                be
                    = CALCULATE ( be, ALL ( 'Table'[sub2] ) ),
                be = 0),TRUE())


RETURN
    IF (
        a&&b,
        BLANK(),be
        
    )
