Grand total for rows only in pivot table

[sharshra]

I understand grand total for rows can be added in pivot table with calculated fields. The calculated field is not impacted by selection or no selection of grand totals option. Does the option to keep grand total on columns only has any relevance? Even if I keep grand totals for columns only, total in calculated fields are still displayed. It makes no difference if I select or don't select grand totals on rows only.
