Pivot Table Too Large?

My source data table is 74 columns and 1,297 rows. I am trying to create a
pivot table with multiple columns from the source data as the "data" in the
pivot table. When I try to do this I get an error that says...
"Excel cannot make this change because there are too many row or column
items...."

Is there a limit on the size?

Any suggestions?
Thanks!
