Need help creating Running Total & Rank

Munch00 Definitely makes a difference. Here are the adjusted formulas and the PBIX is attached below.

Rank Measure v1 = 
    VAR __Segment = MAX('Raw file v1'[SEGMENT])
    VAR __BU = MAX('Raw file v1'[BU])
    VAR __Line = MAX('Raw file v1'[Line No.])
    VAR __Table = SUMMARIZE( ALL('Raw file v1'), [SEGMENT], [BU], [Line No.], "__TotalAmt", SUM('Raw file v1'[Total Amt]))
    VAR __Table1 = ADDCOLUMNS( __Table, "__Rank", RANKX( __Table, [__TotalAmt]))
    VAR __Result = MAXX(FILTER(__Table1, [SEGMENT] = __Segment && [BU] = __BU && [Line No.] = __Line), [__Rank])
RETURN
    __Result
