You need to add square brackets around the table name.
SELECT * FROM [Case]
But how do you get BusinessObjects to do that? Well, you could create a derived table that is just a simple select so that you can put those square brackets around the table.
I’ll have to research further to see if there are other options.
I am assuming you are using the Information Design Tool (generates .unx universes) and not the Universe Design Tool (generates .unv universes).
Within the data foundation if you right-click on a table you can specify a delimiter for that table and/or its columns. That will force double-quotes around every instance of whichever you pick.
