Hi Ric
Unfortunately you cannot wrap the text in the data area of the pivot table, only the text in the column header area of the pivot table can be split between two lines using "\n".
If you have string displayed in the data area of a table your only choice would be using "\n" in the composite table with the "Multiple Lines" option checked for the string parameter in the "Columns" tab in the table properties.
Best regards,
