Hi,
I have a datable like this:

the name of the last column is "Quality".
I would like to create new column in the same datatable with these informations:
Column Table( Grouping Columns( :Quality ), Statistics( Row % ) with Grouping Columns( :Product, :Year, :Month, :Week, :N° date ).
I know I can create a new table from Tabulate but I would like to have all these informations in the first data table, it will be more practical to build different graphs with only one data base.
is it possible?
thanks for your help.
best regards
