Importing the model from ERwin

In order to import a model created in ERwin, you first need to export the model from ERwin to an XML file and then copy the XML file to the Compose Server machine. Note that when you import a model from ERwin, you need to create the Mappings ETL scripts manually. You can either do this by creating global mapping as described in Managing global mappings below or you can create the mapping ETL directly in the Data Warehouse panel.

For more information on creating the ETL mapping(s) in the Data Warehouse panel, see Creating and managing the data warehouse .
