If you want an easy way to understand what situations are distributed and where they are distributed (without having to get into the situation editor for each one), this technique may prove useful.
You can create 2 custom queries that go against the TEMS. The first is:
SELECT DELTASTAT, UNIQUE(SITNAME) FROM O4SRV.ISITSTSH WHERE DELTASTAT = 'S';
This will show a list of what situations are distributed.
The second queries is:
SELECT NODEL, OBJNAME FROM O4SRV.TOBJACCL WHERE OBJNAME = $SITNAME$;
This will work to show where a situation is distributed (passing a variable SITNAME).
You can go from the first query on the first workspace to the second using a link and passing SITNAME as the variable for the drill down. Above is an example of what you would get.
This is a good exercise in custom queries and using workspace links. Here is a URL that describes the set up in more detail:http://www-01.ibm.com/support/docview.wss?uid=swg21454974&myns=swgtiv&mynp=OCSSZ8F3&mync=R
