I guess I’m just not understanding very well. You can use a table as your data item in the report if that’s what you mean.
When you say you “want to use the record as a field”, that is not possible. Records are NOT fields, they are made of fields. You have to choose exactly what fields you want to display and put each of those fields in a different text box in the body section of your report.
If you are trying to setup a report try using the Report Generation Wizard to generate a sample report or generate something to start with. Or design an existing report to see how it is done. Report 10046, Customer Register, is one that shows you a lot without being confusing.
And again, you should really read the NAV documentation for development or report design. You can find it on PartnerSource or CustomerSource.
