I already demonstrated the answer to your question in my first response to your Discussion.  But to further exempliphy the issue, here is a script to illustrate the method.

Names Default To Here( 1 );

// Open a data table and use the variable "dt" as a pointer to the table
dt = Open( "$SAMPLE_DATA\big class.jmp" );

// Select all females in the data table
dt << select where( :sex == "F" );

// Create a subset of the data table and use the variable "dtSubset" as
// a pointer to the new data table
dtSubset = dt << subset( selected rows( 1 ), selected columns( 0 ) );

// Run a bivariate platform on the original data table, explicitly pointing
// to the table by using the "dt" reference to it
dt << bivariate( x( :Height ), y( :Weight ) );

// Run a Multivariate platform on the subsetted data table, pointing the platform
// to use the subsetted table by pointing to the reference variable "dtSubset"
dtSubset << Multivariate(
	Y( :age, :height, :weight ),
	Estimation Method( "Row-wise" ),
	Matrix Format( "Square" ),
	Scatterplot Matrix( Density Ellipses( 1 ), Shaded Ellipses( 0 ), Ellipse Color( 3 ) )
);

Look at the thumbnails at the bottom of each of the data tables created, and you will see that each table only has one platform linked to each table.  Thus showing that the correct table was referenced for the proper platform.

Hello, Jim
I understand what you writing.
But can you give me some example on how to point properly to the different data table?
Thanks.

My point was not asking if you had two different data tables, I assume that.  My point was are you making sure that your code is pointing properly to the different data table.  Are you using making sure that you are specifically pointing to the data table by name or by a unique reference pointer?  Thus my sample code where "dt" and "dt2" were referenced.
