In the Business Model and Mapping layer of the Administration Tool, double-click a logical table source. 2. In the Logical Table Source dialog, click the Content tab and perform the following steps using Table 10–2 as a guide. 3. If a logical source is an aggregate table and you have defined logical dimensions, select Logical Level from the Aggregation content, group-by list. Then, in the Logical Level list, select the appropriate level for each logical dimension table to which the logical fact table is joined. You should specify a logical level for each dimension, unless you are specifying the Grand Total level. Dimensions with no level specified are interpreted as being at the most detailed level.

4. To specify fragmented table definitions for the source, use the Fragmentation

content box to describe the range of values included in the source when a source represents a portion of the data at a given level of aggregation. Time Day Detail Account Organization Account Detail Opportunity Opty Detail Primary Visibility Organization Detail Employee Detail Assessment Detail Contact W_PERSON_D Detail FINS Time Day Positions Details Caution: Although you have the option to specify aggregate content by logical level or column, it is recommended that you use logical levels exclusively. If you must define content by columns, do the following: 1. Select Column from the Aggregation content, group-by list. 2. In the Table pane, select each logical dimension table that defines the aggregation level of the source. 3. In the Column pane, select the logical column for each dimension that defines how the aggregations were grouped. When there are multiple logical columns that could be used, select the one that maps to the key of the source physical table. For example, if data has been aggregated to the Region logical level, pick the logical column that maps to the key of the Region table. Do not mix aggregation by logical level and column in the same business model. Table 10–1 Cont.

This option is only for multiple sources that are at the same level of aggregation. For example, one logical table source might point to records for people with last names A-M, while a second logical table source might point to records for people with last names N-Z. 6. Optional To limit the number of rows the source uses in the resultant table, specify WHERE clause filters in the box labeled Use this WHERE clause filter to limit rows returned exclude the WHERE . You can enter the WHERE clause directly, or you can click the Expression Builder button to open the Expression Builder, create the WHERE clause, and click OK. See About WHERE Clause Filters for more information.

7. If the values for the source are unique, select the option Select distinct values.
