Schema Tab (Dimension Editor Schema View)

Use the Schema tab to display the dimension tables. Joins are indicated by lines connecting the key columns between the tables.

In the Schema tab, you can organize the structure of the dimension in a graphical display, add additional tables and levels, and browse the data in the dimension tables.

To view all columns in a table, lengthen the table window vertically, or use the scroll bars. You can also widen the table window to view long column names.

Note  Changing the structure of a dimension causes the results of previous dimension processing to be invalidated. After the structure of a dimension has changed, you must process the dimension to re-create the data.
