Josef.Select your source cabinet, then in the match code section select "File Cabinet Database". Select the same file cabinet. You can then match on "Doc Id" equals "Doc Id".

thank you for pointing this out to me. I got confused by the new name being Doc ID instead of DWDOCID.
That happened to me too. By the way, the "File cabinet database" option is a lot faster than the old external database method.
