Mapping elements and creating hierarchies

For mappings of source tables to OLAP dimensions, you specify, which source elements to import later. When you specify the source elements, you do not yet create a hierarchical structure.

You create the hierarchical structure in the target dimensions. The source elements that you have selected in the mapping, may be imported from the Unified data sources tab in the data area of the target dimension.

In the target dimension, you assign source elements to target elements and thus create the hierarchical structure of the dimension. There are different possibilities to process source elements, for example, to assign several source elements to one target element, or to create a target element for each source element.

Note: To import data, you must create the OLAP cubes from several dimensions. With data connections for cubes you specify, which data are written into these cubes.
