Open the sub report designer and use the following binding to the report's DataSource property
Property path: DataSource
Thus when added in a SubReport item, the report will get its data from the DataObject
of the SubReport item. Using the Parent key word you can go up the hierarchy of elements and get the whole report data e.g. =ReportItem.Parent.Parent.Parent.DataObject
for a sub report placed in a Detail section of report without groupings.
I hope this helps you.
