Thanks for your reply.

The datasets that will be "pushed" to the report don't follow the exact structure of the database tables, since are created from joins between multiple tables.

I like to use datasets and the "push model", instead of views or sps, since I like to have full control over the data.

What about "field definition" files. Are worth to look more into it? How can I create them? (I'm using the .NET version of Crystal Reports).

Thanks,
Stefanos

In the brief but eloquent words from our architect:

"It was the old technology (Field Definition). Don't use it."

Well, if you must create a report without using strongly typed DataSets or a database, then here is a doc on how to create *.ttx files for use with crdb_fielddef.dll:
