The only way is to make the other table to be made pretend to be belonging to the livelink schema.
For eg if you use this query for your tablekey thing
select * from dtree where subtype=0 the resaon it works is because livelink knows it as table in its database.
So using SQlserver or Oracle it should be possible to create an entry in the livelink schema for your foreign table. Livelink will not know its difference.Check with your DBA for the specifics about it
Several companies have asked for this feature including me,so you should have your company added to it.
I think you already know webforms can query external database tables and a kludged soln using workflows could be conceived as well
Well, if I called the wrong number, why did you answer the phone?
