Queries with Hierarchically Displayed Axis and Conditions
If you define conditions for queries in which you display the axis hierarchically, make sure that you expand the hierarchical display up to the characteristic that the condition is to affect. You have to make the setting Expand to <characteristic> in the context menu for the associated axis (rows or columns) in the Query Designer. You can also make this setting using the Web during runtime. In the context menu for the Web application, choose Query Properties and make the appropriate setting under Preparation of the Data (see Query Properties).

Also note that manually expanding the nodes during runtime is not enough. The drilldown level must be set using the Expand to <characteristic> function so that the condition can be applied.

You can find more information under Query with Hierarchically Displayed Axis and Conditions.

With the set value, the unassigned nodes of a hierarchy in the query are not displayed. If the value is blank, the other nodes are displayed. The unassigned nodes of a hierarchy are the master data of the InfoObject for which the hierarchy was created and which are not contained in the hierarchy as a node.
