Use the DROP
DIMENSION
statement to remove the named dimension.
This statement does not invalidate materialized views that use relationships specified in dimensions. However, requests that have been rewritten by query rewrite may be invalidated, and subsequent operations on such views may execute more slowly.

Oracle Database Concepts for general information about dimensions
The dimension must be in your own schema or you must have the DROP
ANY
DIMENSION
system privilege to use this statement.
Specify the name of the schema in which the dimension is located. If you omit schema
, then Oracle Database assumes the dimension is in your own schema.
Specify the name of the dimension you want to drop. The dimension must already exist.
Dropping a Dimension: Example This example drops the sh.customers_dim
dimension:
DROP DIMENSION customers_dim;
