Import configuration error

Hello

There is a Oracle error when I open a zip file on import configuration windows .

ORA-06502: PL/SQL: numeric or value error: Bulk Bind: Truncated Bind

It’s about a Custom Event  nammed “0^FGAEVQUA004^MrbPartInspection”

I checked parameter “Define the characters which should not appear in key fields” , it contains “(..)&%_<>=;~”

The event already exist in an application package .

Thanks for your help
