From Denodo Platform 8.0, the **option to view the Query Capabilities has been removed**. You can find this information in the [Removed “Query Capabilities” Panel](https://community.denodo.com/docs/html/browse/8.0/en//platform/upgrade/backward_compatibility/changes_in_the_denodo_platform_8.0/features_removed_from_virtual_dataport#removed-query-capabilities-panel) section.
If I would need to change the Query Capability of a view and make a column mandatory, I would do the following,
* Open the Base view > VQL.
* Copy the VQL of the Base view and paste it in the VQL shell.
* Edit the ADD SEARCHMETHOD <view_name> section of the VQL to change the obligatoriness of a column. For example,
***ADD SEARCHMETHOD <viewname>(
ADD <columnname> (any) OBL ONE
* Execute the VQL.
Now, open the base view, navigate to **Options > Search Methods** tab, you will find the column_name in the Mandatory fields row as shown [here](https://community.denodo.com/docs/html/browse/8.0/en//vdp/administration/creating_derived_views/advanced_configuration_of_views/search_methods_and_configuration_properties#search-methods-of-a-base-view).
For more information, you could refer to the [Example of how a search method is created with ALTER TABLE](https://community.denodo.com/docs/html/browse/8.0/en//vdp/vql/creating_a_base_view/query_capabilities_search_methods_and_wrappers/example_of_how_a_search_method_is_created#example-of-how-a-search-method-is-created-with-alter-table) section of Virtual DataPort VQL Guide.
Hope this helps!
