Build the project that contained the deleted design-time file Execute a DROP statement in an SQL console connected to the HDI container. Build the folder that contained the deleted design-time file . Execute the refactor function for the calculation view. A cube calculation view consumes a dimension calculation view. You rename the design time file of the dimension view but do NOT choose the option to rename the runtime view and adjust the reference. Afterward, you perform the following operations: A: Build/deploy the dimension calculation view as a single object. B: Build/deploy the entire SAP HANA database module. What is the outcome of the build/deploy operations? . A is successful. B Fails. A fails. B is successful. A fails. B fails. . A is successful. B is successful. You create a user-provided service to access tables in external schemas. In which file type do you assign the user-provided service to your database module? hdiconfig .mtar .namespace .yaml.
