How to find Infoobject is in Free Characteristic or in Row in Bex using SAP tables

Hi,

I have a list of 2000 queries wanted to know particular infoobject is present in Free characteristic or in row of query ,pls provide me some tips how i can find it.

I have tried using table

RSZSELECT

RSZELTDIR

RSZELTXREF

RSRREPDIR

With smart use of above table i can find out whether infoobject is used in query or not, but still no success in finding whether infoobject is present in Free Characteristic or in Row , i don't want to sit and open one query at a time in query designer or in metadata to find these details.

Regards,

Ajit Mishra.
