Hi mmar141 ,

If you mean the data type in Table1, Table2 and Table3 is Date, but in the new created table is text, here's my solution.

1.Delete the relationships betwen the four tables.

2.Modify the measure to:

Measure =
SWITCH (
    MAX ( 'Table'[TableName] ),
    "Table1",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table1' ), 'Table1'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table1' ), 'Table1'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAXX (
                FILTER ( 'Table1', 'Table1'[Date] = CONVERT ( MAX ( 'Date'[Date] ), DATETIME ) ),
                'Table1'[Calculated Pass/Fail]
            )
        ),
    "Table2",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table2' ), 'Table2'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table2' ), 'Table2'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAXX (
                FILTER ( 'Table2', 'Table2'[Date] = CONVERT ( MAX ( 'Date'[Date] ), DATETIME ) ),
                'Table2'[Calculated Pass/Fail]
            )
        ),
    "Table3",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table3' ), 'Table3'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table3' ), 'Table3'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAXX (
                FILTER ( 'Table3', 'Table3'[Date] = CONVERT ( MAX ( 'Date'[Date] ), DATETIME ) ),
                'Table3'[Calculated Pass/Fail]
            )
        )
)

Get the correct result:

I attach my sample below for your reference.

Hi mmar141 ,

According to your description, here's my solution.

1.Create two tables.

Sort Date column by Index column, then make relationship between Date table and other tables with Date column.

2.Create a measure:

Measure =
SWITCH (
    MAX ( 'Table'[TableName] ),
    "Table1",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table1' ), 'Table1'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table1' ), 'Table1'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAX ( 'Table1'[Calculated Pass/Fail] )
        ),
    "Table2",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table2' ), 'Table2'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table2' ), 'Table2'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAX ( 'Table2'[Calculated Pass/Fail] )
        ),
    "Table3",
        IF (
            MAX ( 'Date'[Date] ) = "%",
            DIVIDE (
                COUNTROWS ( FILTER ( ALL ( 'Table3' ), 'Table3'[Calculated Pass/Fail] = "P" ) ),
                COUNTROWS (
                    FILTER ( ALL ( 'Table3' ), 'Table3'[Calculated Pass/Fail] <> BLANK () )
                )
            ),
            MAX ( 'Table3'[Calculated Pass/Fail] )
        )
)

In a matrix, put TableName in Rows, Date in Columns and measure in Values, get the correct result:
