Complex Fields Types
At the moment Crystal is not supporting complex fields like:

Complex Fields Names
There are some restrictions on the use of special characters and punctuation signs in some fields, and in particular:
Crystal doesn’t support column names that contain special characters like .(),%$…

Crystal doesn’t support periods inside the schema name
Crystal doesn’t support column names that include "/" for dynamic filters
