QUESTION 54
You have imported a new calculation view in a folder that contains an .hdinamespace file. This calculation view consumes one data source, which is a table. When trying to deploy the calculation view, the deployment fails with a namespace-related issue.What could be the reason?Note: There are 2 correct answers to this question.

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

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

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.

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