Importing a Data Model

The File Import function is developed to allow importing of the data model files defined by external model editors like Visual Studio (edmx files) and the metadata files types (xml) into the Service Builder to create a data model. This feature can be used in the following scenarios:

• To import a metadata/edmx file for a new project. In instances where you create a project and import a file.

• To import a metadata/edmx file for an existing project, which already has a data model created (re-import). In this case, the existing data model will be overwritten.

Ensure that the virus scan profile /SCET/GUI_UPLOAD is Active and selected as Default Profile in the SAP system.
