Hierarchy level logic

[glycine76]

Hello, 

Let's say I have a data structure like this

Level 1        Level 2          Status

A                    A1              Approved

A                   A2                 Approved

A                 A3                  Approved

B                    B1             Review

B                     B2              Approved

B                   B3                Review

C                  C1                Approved

C                 C2                Approved

C                C3                       Approved

Only when all items in level 2 are approved, level 1 items are approved. So how do I write a measure to count how many level 1 items are approved? 

Thanks for the help in advance!

@glycine76 ,

There are many ways... You can try this:

FinalStatus = 
VAR t = 
    ADDCOLUMNS (
        DISTINCT ( Table[Level 1] ),
        "approved",
            VAR c_level = CALCULATE ( SELECTEDVALUE ( Table[Level 1] ) )
            VAR level1count = CALCULATE ( COUNT ( Table[Level 1] ), Table[Level 1] = c_level )
            VAR statusCount = CALCULATE ( COUNT ( Table[Status] ), Table[Status] = "Approved" )
            RETURN
                IF ( INT ( statusCount = level1count ) = 1, 1, BLANK () )
    )
RETURN
SUMX ( t, [approved] )
