Table Interface / Web: value from free characteristic

Hi,

i am using 2 queries. In the first query i got the free characteristic "calendar year month". Now i created a link with table interface to jump to the second query. With this link i would like to filter query 2 with calendar year month from query 1. How can i get the value from the calendar year month? With drill down there is no problem to get the value in method CHARACTERISTIC_CELL. But with free characteristics this is not so easy.

Any ideas?

Regards,
