Are they calculated in stored functions in the database? If so, you can do one of two things:
1. If you're using the "standard" Crystal methodology of linking tables together in the report, you should be able to create a SQL Expression for each of these fields that you need. A SQL Expression in this case would just use the same syntax from your database that you would use to pull that "field" in the Select clause of a query.
2. Instead of linking the tables together, you could write a "Command", which is the full SQL Query that you would use to pull all of the data for your report.
