I have a field alled workgroup that contains null values and the entire record does not return. How do I stop CR from surpressing null fields?

CR won't supress nulls by default. If you have set it to supress nulls, uncheck dupress nulls. Otherwise check your joins, selection formula etc

Agree.  Is this a single table report?

Are you doing any filtering of the data?

Yep, I get into that trap all the time until I remember to use an outer join.

If you link with inner joins on some field that has a null value, you won't get the data.

What I sometimes try if I am really lost, I take the query out of Crystal and run it on the database (SQL Server Enterprise Manager in my case) and take things out and change joins until the record appears, then I see where I was wrong.
Mostly happens Monday mornings and Friday afternoons :)

ALso if you a filtering on the subordinate table then Crystal changes all joins to INNER because it can't compare the NULL from no record to the value.
