Diagnosis
Single filters are currently not required for the parameters andcharacteristic hierarchy.
The corresponding functions have been suppressed, which means thatalthough you cannot generate these two categories, the functions willstill be available for implementation at a later date.
The category "filter group" (AND link) can always be mapped usingdynamic selections. The filter group is designed to enable dynamicselections from existing single filters to be grouped. Since it isbased on single filters, the filter group is also no longer required.

System Response
You cannot create filters with the categories "single filter" and"filter group".
However, you can still process existing filters in these categories. Inthis case, the system issues a warning message.
