In some of your analyses, you may notice that certain dimension hierarchies have a value called “Not Assigned” on Level 0 of a hierarchy, with the other values not appearing until the bottom level.

  • SAP NetWeaver Business Warehouse


Work with your SAP BW administrator to resolve this data modeling issue. By default, a "Not Assigned" node is added to the hierarchy.

For example: suppose there are 1000 characteristic values for the characteristic “Material”. A hierarchy with material groups from a total of 100 materials is defined for it. The remaining 900 (1000-100) characteristic values, are positioned under node Not Assigned.


This issue occurs when there are characteristic values that do not appear in a hierarchy.
