Creating A Bw Query In Sap Business Explorer Query Designer - IBM Cognos User Manual

Before you begin
You can use Cognos Transformer to import both dimensional and fact data from an
SAP BW query source. The following instructions describe how to rebuild an SAP
BW cube as an IBM Cognos Transformer cube. To do so, the SAP BW query
package must be in a specific format.
There are three stages to importing a SAP BW query to access both dimensions
and facts using IBM Cognos BI:

You must create a query that includes the cube that you wish to import. We
recommend that you base the query on a single InfoCube in the database. A query
based on multiple sources may result in SAP BW errors during data retrieval.
After creating the query, you can create a variable "Create a Variable" on page 341.

example, Columns or Rows.
The characteristics you select will define the metadata in the Cognos
Transformer cube. The characteristics must adhere to the following restrictions:
v You must have at least a single optional variable to segment the data.
v Select a characteristic that is representative of the data source. The
characteristics can be either key figures, which will become measures in
Cognos Transformer, or dimensions, which will become the Cognos
Transformer dimensions.
v Do not assign any of the characteristics a display hierarchy, either explicitly
or by a variable.
v All key figures in the SAP BW query must be numeric.
v Do not select the Currency/Unit characteristic.
v Ensure that all selected key figures use the same currency.
v Only include characteristics in the SAP BW query that you wish to extract
using Framework Manager. Including unnecessary characteristics increases
data volume, thereby adversely affecting performance.
v Characteristics must be copied to the Columns or Rows fields of the query
definition. If copied to the Free Characteristics or the Filter fields, the
characteristics show as dimensions when importing from the package but the
stream extract processing is not able to fetch the values.
v If you have filters defined, they must reference only dimensions that have
been included elsewhere in the query definition.
