When I startERwin and goes to the Target Server window.Teradata is greyed out and I'm unable to select this. However DB2, Oracle are both fine. I'm not the only one having this issue in our group.
Go to Help-about ERwin Data Modeler, you will see your ERwin is Community Edition, which has limited DBMS
support, and only allows 25 entities/tables.
You need to get a working license file for ERwin Workgroup Edition or ERwin Standard Edition, and apply the license file.
You can get your license through the following link:
or call +1 800 225-5224 option 2-1-2
