With the SAP HANA Live extension assistant, you can extend query or reuse views delivered by SAP. The tool is an eclipse plug-in for the SAP HANA studio.
Extending reuse views
You can extend reuse views using this tool. The extended views are created as new reuse views in the package you selected. The tool lists all the underlying columns from all underlying tables of a reuse view. You can select the column that needs to be added as an output of the view and a new extended reuse view is created. The newly added view column can only be of the type Attribute.
Extending query views
You can extend query views using this tool. The extended views are created as new query views in the package you selected. The tool lists all the underlying reuse views of a selected query view. For each of the reuse views, unused columns are displayed. You can select the required columns to be added to output of the view from the underlying reuse view. To extend query views, you can select underlying reuse views or extended reuse views.
Extending existing extensions
You can also extend views for which an extension already exists.
You can only select packages if you are authorized to create or activate content in these packages. SAP does not recommend that you modify any views created by the tool using the Modeler perspective. Note that, if you do, the tool can no longer be used to modify the views.
