That add in is very fussy.... The usual problems are the following.
1. The two files being compared cannot be traced back to the same
originatiing file. For example, if I start a file in January and then make
monthly updates, I should be able to compare July/August because they can be
traced back to the same parent (January).
2. When you run the utility, it also asks for a table to use as the basis
for comparison. I have a bad habbit of add/delete columns from the views
which changes the structure of the tables (shame on me). If the structure of
the underlying tables is different, this may also cause problems.
If you suspect number 2 is the problem, you may want to try replacing the
tables in your file with the ones from the Global.mpt. You can do that with
Tools/Organizaer. Pull the tables tab and then copy from the Global.mpt on
the left to the file tables on the right. See if any of that helps.
Sometimes I create a new table called "Compare" and make sure they are the
same in both files.
Let's hope our Redmond Friends can make this a bit more stable soon.
