You have imported a new calculation view into a folder that contains an .hdinamespace file. This calculation view consumes one data source, which is a table. When trying to build the calculation view, the build fails with a namespace-related issue.What could be the reason? Note: There are 2 correct answers to this question.

The imported calculation view and its data source have different namespaces.

The namespace used within the calculation view to reference the table is different from the actual namespace in the identifier of this table.

The .hdinamespace specifies 'sub-folder':'append', so calculation views can only be created in subfolders.

The imported calculation view and its data source have different namespaces.

The namespace used within the calculation view to reference the table is different from the actual namespace in the identifier of this table.

An .hdinamespace file is defined in the src folder that specifies a different namespace property than the one in the identifier of the calculation view.
