Overflow Error Occurs When a Value in a Crosstab Is More Than 19 Characters

In a crosstab report, values support a maximum of 19 characters, including the decimal point. If a value exceeds 19 digits, an overflow error occurs. By default, the decimal precision is set to 7 digits, which restricts the number of integers to 11 digits.

To use more than 11 integers, you must edit the qfs_config.xml file in the install_location\configuration directory. For more information, see the section about reducing decimal precision in the IBM® Cognos® Analytics Administration and Security Guide.
