Column Header names should contain current month dynamically

Hanuma_Srikiran,

You may use the following DAX to add a new table and then use the Matrix visual.

Table2 =
UNION (
    SELECTCOLUMNS (
        Table1,
        "ID", Table1[ID],
        "Attribute", DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 1, 1 ),
        "Value", Table1[PREVIOUS MONTH SALES]
    ),
    SELECTCOLUMNS (
        Table1,
        "ID", Table1[ID],
        "Attribute", DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ), 1 ),
        "Value", Table1[CURRENT MONTH SALES]
    )
)
