When you create a new rule project item, follow the naming conventions.
Make sure that you use the Java™ naming conventions when you create a name for your rule project items. You can use spaces because they are processed into valid characters when you execute, but do not use spaces at the beginning of a name.
The name of a rule project item must not:
Be empty
Be longer than 255 characters
Start or end with white space characters
Contain the characters ",.,:,*,/,<,>,?,\, or |
Contain a character that has a ASCII or Unicode code below 0x1f, included
