Hi Uma_Dhandpani ,

It seems your description is a little bit different with above post, I've created a pbix based on your question:

Measure = 
IF (
    HASONEVALUE ( 'Table 2'[Currency Mode] ),
    IF (
        SELECTEDVALUE ( 'Table'[Attribute] ) = "BaseAmount",
        CALCULATE (
            MAX ( 'Table'[Value] ),
            FILTER ( 'Table', [Attribute] = "BaseAmount" )
        )
    ),
    IF (
        SELECTEDVALUE ( 'Table'[Attribute] ) = "Total amount",
        CALCULATE (
            MAX ( 'Table'[Value] ),
            FILTER ( 'Table', [Attribute] = "Total amount" )
        )
    )
)

pbix attached.
