When the area structure is defined in the Area Dialog Box it defines the levels at which all the tables in the Tabulation application will be tallied. This can be modified for individual tables using the Tally Attributes for a Table.
The last section in the menu allows the selection of a lowest area break level for this table only. By default it will be set to the lowest area level available.

In the example above, if a certain table is to be produced only at the province level then that item would be selected as the Lowest Break Level instead of district.
