How do I make "Process Capability" with data table including limits and target?

[#1]

Could you tell me how to make Process Capability with a data table including LSL, USL, Target?

------------------------------------------------------------------------------------------------------------------------

I have the data table including LSL, USL, Target.

I use Column Dialog and select columns for Process Capability.

But... It doesn't work with error msg "Process Capability cannot be launched because none of the processes can be found in the data table."

Could you tell me how to fix it?

My some part of JSL is below.

//dt <- limits & target

For( m = 1, m < N Col( dt ), m ++,
	Eval( Eval Expr( Column(dt, m) << Set Property("Spec Limits", {LSL(Expr(lower_limit[m])), Target( Expr(target_val[m]) ),USL (Expr(upper_limit[m]))})));
);

//Select Test Item for Process Capability
colDlg = Column Dialog(
	Title( "Test Item Selct" ),
	ycol = Col List( "Test Item", Min Col( 1 ), Max Col(15) ), //
);

Show (colDlg["ycol"]);

pc =dt << Process Capability(
	Process Variables(:colDlg["ycol"]
	),
	Moving Range Method( Average of Moving Ranges ),
	Overall Sigma Summary Report( 1 ),
	Goal Plot( 0 ),
	Capability Index Plot( 0 ),
	Process Performance Plot( 0 ),
	//Order By( "Overall Sigma Ppk Ascending" )
);

Thank you.

Change

	Process Variables(:colDlg["ycol"])

to

	Process Variables(Eval(colDlg["ycol"]))

Full example

Names Default To Here(1);

dt = Open("$SAMPLE_DATA/Semiconductor Capability.jmp");

colDlg = Column Dialog(
	Title("Test Item Selct"),
	ycol = Col List("Test Item", Min Col(1), Max Col(15))
);

pc = dt << Process Capability(
	Process Variables(eval(colDlg["ycol"])),
	Moving Range Method(Average of Moving Ranges),
	Overall Sigma Summary Report(1),
	Goal Plot(0),
	Capability Index Plot(0),
	Process Performance Plot(0)
);
