Description: When two instances of erwin DM r8 and r9 are running on the same computer, with two different data models open, the query tool will fetch data from the data model opened first for both instances of erwin. The result of the query tool will be for the data model opened first. Why is this happening?
Solution: You can only have one instance of erwin DM Query Tool reporting at a time on a computer by design. The way to get the data from the other instance of erwin Data Modeler's Model is that the first erwin Data Modeler's Model will have to stop the Reporting, by clicking, Tools | Options | Reporting - Stop ODBC reporting and then the other user will have to start reporting (or can report correctly).
