Tip 1: Don’t go too far down the data source tree to select fields. If you have a choice in data sources, choose the one that has the LEAST number of tree branches.
For example, both the Item and Bibliographic Record sources contain title and author information. Yet if the report to be created must include circulation modifier in addition to title, the Item data source is the better choice. To obtain the circ modifier, one must go down six (6) branches within the Bibliographic Record data source. For Item, only two (2) branches are necessary.
Tip 2: Stick to the recommended core sources, rather than choosing tables from the "Other Sources" section of the list.
Tip 3: The most common core sources are ILS User, Item, and Circulation. Try to start from one of these tables if you're not sure where to start.
