Use characteristics as key figure in Input query BW IP

Dear all

i already found many blogs where this feature is described

Use 'characteristics as key figures' in input query BW-IP

Now we did it BUT we cannot use it as we get this error . We use Bex Analyzer.

"Key figure ZXXX is not input ready in this filter and drilldown combination"

Now i just read in an old blog (2014): "BEx Analyzer does not support this feature, 'characteristics as key figures' there are always display only."

is it still a problem with bex analyzer? we can only use this feature with AO?

thank you

Melanie
