Effective in version 10.2.2, and starting with the Winter 2019 March release of Informatica Intelligent Cloud Services, field names in complex file data objects that you import from an intelligent structure model can begin with numbers and reserved words, and can contain the following special characters:

\. [ ] { } ( ) * + - ? . ^ $ |

When a field begins with a number or reserved word, the Big Data Management mapping adds an underscore (_) to the beginning of the field name. For example, if a field in an intelligent structure model begins with OR, the mapping imports the field as _OR. When the field name contains a special character, the mapping converts the character to an underscore.
