For tables that use relational data, you can add a column that shows a selected
measure as a percentage of a grand total. For relational crosstabulation tables, you can
show a selected measure as a percentage of a grand total, a column total, a row total,
or a subtotal. For multidimensional crosstabulation tables, you can show a selected
measure as a percentage of a grand total, a column total, a row total, a column subtotal,
or a row subtotal.
