Exclude Values Filter

Hello Everyone,

I need to create  (not equal) filter in design studio, but i couldn't find a proper way to do this. Even in initial view when i use background filter; i can't specify the filter property "not equal".     By using setfilterExt (dimension, input string)  script, it seems that can be achieved as it is explained like :

InputString

The SAP Business Explorer Selection Syntax (Input String Syntax) allows you to specify more complex selections, for example intervals and excluding sections:

I have  created a structe at Bex,  and let's say i need to filter out the row  named "A" from the structure.

setfilterExt (my_structure, "!A");   didn't do the trick.  Also the data source didn't bring any other results.  Where am i doing wrong any ideas?
