Copy selection and paste into new columns

Hello, I have a set of columns with data for multiple products by rows. I need to split up this data by creating new identical columns with product name suffix and copy over only the matching product data from previous columns. I just need help to copy over appropriate data. I was trying to do this with selections and copy paste, but I am not sure how to. Region of interest is starting from dt << Select Where onwards.

Names Default To Here( 1 );
dt = Current Data Table();
colNames = dt << Get Column Names(String);
//Select set of columns to split
for (i = nitems(colNames), i > 0, i--,
     if (!contains(colNames[i], "SPC"),
           remove from(colNames, i);
     );
);

//Add new columns with product name suffix and copy/paste properties
Summarize(unique_values=by(:Products));
colNames2=colNames;
for (k = nitems(unique_values), k > 0, k--,
	for (i = nitems(colNames), i > 0, i--,
		colNames2[i] = colNames[i] || " " || unique_values[k];
		dt << New Column( colNames2[i] );
	); 
	for( j = 1, j <= nitems(colNames), j++,
		colProps = Column( dt, colNames[j] ) << Get Column Properties;
		Column( dt, colNames2[j] ) << Add Column Properties( colProps );
	);
<U><STRONG>	dt << Select Where( :Products == unique_values[k] );
		dt << selectColumns(colNames);
		dt << Copy;
		dt << selectColumns(colNames2);
		dt << Paste;</STRONG></U>
);

 

Data Blending and CleanupRe: Copy selection and paste into new columns

Hi, If you want to copy and paste value based on row selection, you can write code like the following.

I hope it helps.

dt << Select Where( :Products == unique_values[k] );
r = dt << Get Selected Rows();
val = As Column( colNames[i] )[r];
For( h = 1, h <= N Row( val ), h++,
 As Column( colNames2[i] )[r[h]] = val[h]
);
