Exporting data from Directory with Modified Date Info

I have exported the list of groups from our Domino Directory to a CSV file.

I modified the view in Designer so it exports the administrator of the group. I also want to export the “Last updated” field but I can’t find that field in Designer. There are hundreds of feilds but no the one I need. Can someone advise as to which feild I can use or the LotusScript that would work.

Ultimately, we want to be able to have a list of all groups along with who administers it and when they last modified it so we can identify old groups that are no longer needed. Is there another way I can do this…other than manually look at each group?

Thanks,

Greg
