Urgent Help Please, Error with Nested Table

Question

Hello All,
I'm trying to create data mining models based on some medical data. I have combined two tables (Patients) and (tumors) into one table (cancer_patients). In the (cancer_patients) table there is one column (tumors) as nested table column. So I got the following error (ORA-22913) about the nested table. I need an advice about how to fix this error in ODM please
This is the code of the tables
CREATE TABLE "DSS2_MINING"."PATIENTS"
   (     "PATIENT_ID" VARCHAR2(10 BYTE) NOT NULL ENABLE,
     "REGISTRY_ID" NUMBER(10,0),

Hi
i was using AWM since 9i just because it creates OLAP metadata with a new API called CWM2, and Oracle Enterprise Manager was using a propietary API .
With AWM 10.1.0.4 building your OLAP metadata is very simple, you can define your Dimensions, cubes, measures and even you can load your data from your source system.
You can refer to the Oracle® OLAP Application Developer's Guide where you can find more information on this tool.
And relative to your error i will recommend that you build on a dimension-by-dimension basis and try to validate your OLAP Metadata.
