By default, VSReport8 uses the ConnectionString and RecordSource properties to create an ADO recordset that is used as a data source for the report. However, you can also create your own recordsets and assign them directly to the Recordset property. In this case, VSReport8 will use the recordset provided instead of opening its own.
You can use three types of recordset: ADO, DAO, or custom. This documentation refers to these recordsets as "custom recordsets". This doesn't mean the ADO and DAO recordsets are different from regular ones, they are simply provided by the application rather than being created by the VSReport8 control.

NOTE: All recordsets used with VSReport8 must be bookmarkable, because the control needs to be able to save and restore cursor positions in order to detect group breaks and calculate aggregates. |
