Create a Cube Table in the Physical Layer
Manually create a cube table in the semantic model's physical layer when you can't import a multidimensional cube table.
Note:
Oracle recommends that you import cube tables rather than manually creating them.If you manually create cubes, you must build each cube one hierarchy at a
time and test each hierarchy before building another. For example, create the time
hierarchy and a measure and then test the hierarchy. Then when the cube is correct, you
create the geography hierarchy and test it. Creating and testing the cubes you create
manually in this sequence ensures that you've set up each cube correctly, and helps you
identify any errors as you add each element to the cube.
