Where-use of /BIC/M* table

Hi,

Is there any way to find out, where the master data table /BIC/M* has been referenced in the transformation or user exit?

The reason I'm asking is that, I would like to change the structure of one custom InfoObject, however the master data table of this InfoObject has been used in various transformations by looking up this table into internal table for further processing.

So before I make such change, I would like to check the relevant transformation to make sure there is no syntax issue for the structural change.

Any ideas?

Thanks,

Ivy
