SAP BW data sources may have problems with sections
in reports under different circumstances:
If a section in a report uses the lowest-level query item in a ragged hierarchy, such as the children of the not assigned node, the following BAPI error may appear:
BAPI error occurred in function module BAPI_MDDATASET_SELECT_DATA. Value <valueName> for characteristic <cubeName> unknown

The solution is to remove the section from the lowest-level query item.
