MdxScript(Model) (37,5) Calculation error in measure

Hi,

I created a measure that is supposed to be used in a slicer. However inserting it in the slicer field, I get the following error: "MdxScript(Model) (37,5) Calculation error in measure. 'table1'[WA_LIBOR_Spread]: Column[Value] is part of composite key, but not all columns of the composite key are included in the expression or its dependent expression.

WA_LIBOR_Spread =
SWITCH(
    SELECTEDVALUE('Value'[Value]),
    "Facility Commitment Amount P1",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                'table1'[P1_COMMITMENT_USD]
            ),
            SUM('table1'[P1_COMMITMENT_USD])
        ),
    "Facility Commitment Amount P2",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                'table1'[P2_COMMITMENT_USD]
            ),
            SUM('table1'[P2_COMMITMENT_USD])
        ),
    "Facility Commitment Amount Change",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                (COALESCE('table1'[P2_COMMITMENT_USD], 0) -
                 COALESCE('table1'[P1_COMMITMENT_USD], 0))
            ),
            SUMX(
                'table1',
                COALESCE('table1'[P2_COMMITMENT_USD], 0) -
                COALESCE('table1'[P1_COMMITMENT_USD], 0)
            )
        ),
    "Outstanding Balance P1",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                'table1'[P1_FAC_NET_OS_USD]
            ),
            SUM('table1'[P1_FAC_NET_OS_USD])
        ),
    "Outstanding Balance P2",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                'table1'[P2_FAC_NET_OS_USD]
            ),
            SUM('table1'[P2_FAC_NET_OS_USD])
        ),
    "Outstanding Amt Change",
        DIVIDE(
            SUMX(
                'table1',
                'table1'[LIBOR_SPREAD] *
                (COALESCE('table1'[P2_FAC_NET_OS_USD], 0) -
                 COALESCE('table1'[P1_FAC_NET_OS_USD], 0))
            ),
            SUMX(
                'table1',
                COALESCE('table1'[P2_FAC_NET_OS_USD], 0) -
                COALESCE('table1'[P1_FAC_NET_OS_USD], 0)
            )
        ),
    BLANK()
)

where
Value = {
    ("Facility Commitment Amount P1", NAMEOF([P1_COMMITMENT_USD]), 0),
    ("Facility Commitment Amount P2", NAMEOF('table1'[P2_COMMITMENT_USD]), 1),
    ("Outstanding Balance P1", NAMEOF('table1'[P1_FAC_NET_OS_USD]), 2),
    ("Outstanding Balance P2", NAMEOF('table1'[P2_FAC_NET_OS_USD]), 3),
    ("Facility Commitment Amount Change", NAMEOF('table1'[Commitment Amt Change]), 4),
    ("Outstanding Amount Change", NAMEOF('table1'[Outstanding Amt Change]), 5)
}

I'm using direct query mode, and Value is a separate table, that is also used in another slicer, to allow the users to filter the data of the report.

Any idea on how can I fix this?
