Upload File Page (Report Manager)
Use the Upload File page to publish a file from the file system into the report server database. Uploaded files are represented as items in the report server folder hierarchy.
Uploaded .rdl files are published to a report server as reports.
Uploaded .smdl files are published as report models if they contain data source view information. If they are missing a data source view reference, an error occurs during the upload. Data source view information might be missing if you upload an .smdl file from a Microsoft Visual Studio report model project. In report model projects, data source view information is stored in a separate file rather than in the .smdl file itself.
Model files that do contain data source view information (and can therefore be successfully uploaded) are those that have been previously published to a report server and then saved from the server to a file on the file system. If you open the General Properties page of a model and click Edit to open the model, you can save it to a file and then upload it as a new model on the report server. The .smdl file that you subsequently upload will have all of information that is necessary for model publication.
All other file types that you upload are stored as resources. This includes .rds files that contain report data source connection information. Uploading an .rds file does not produce a shared data source item on the report server.
When you upload an item, it is placed in the current folder. After the upload is complete, you can move the item to a different location.
Report models are not supported in SQL Server Express with Advanced Services.
