If you have an object type that does not need to be processed in the Data Warehouse, you can suppress processing by manipulating table WH_LAST_REFRESH in the target database. In that table, find the row where column ENTITY_CODE matches the object type definition. (If such a row does not yet exist, add the row.) Then update column LAST_REFRESH_DATE in that row to a date value that is far in the future, for example, January 1, 3001.
