You must have to create dataSet for crystal report and configure them with your data entities, while return data from your DAL(Data Access layer). When you will create crystal report, it will ask for dataSet, then select the appropriate dataSet you have created for that report, asfter creation, that dataSet will be listed in your field explore for use.
