I started by trying it for just one table and three users:
I created a workbench with a reader for each of the different users and a writer to the new user, and everything worked well.
As I want to automatize as much as possible, I used parameters for the user names and passwords, wrote them in a command file and started it as a batch.
But like that I still have to have a reader defined for each user in the FME Workbench. Is it possible to create the readers "on the fly" in the batch file? Or could I loop with the same reader through a list of my users / passwords?
Thanks in advance
