Hi, I did the following to create a self-referential data source: 1. In Virtual DataPort, create a new [JDBC data source](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#jdbc-sources). 2. From the dropdown list, select the appropriate version of the Denodo Virtual DataPort database adapter (e.g. Denodo Virtual DataPort 7.0) which will fill in the driver class path and the driver class. 3. Provide the database URI and valid credentials for the Virtual DataPort server. Now, I can use ["Create Base View from Query"](https://community.denodo.com/kb/view/document/Using%20the%20Create%20Base%20View%20From%20Query%20Option?category=Data+Sources) on top of this self-referential data source. You can take a look at this Community Q&A of a use case related to self-referential data sources in Denodo: * [Extract the origin of a data source in metadata for report view](https://community.denodo.com/answers/question/details?questionId=9060g000000bmSMAAY&title=Extract+the+origin+of+a+data+source+in+metadata+for+report+view) Hope this helps!
