Problems in the creation of a MOLAP Cube with DBMS_AWM.

Question

I want to create a MOLAP Cube with the package DBMS_AWM. So I create the ROLAP Cube and the Dimensions with the Enterprise Manager Website, and all works perfectly. Then I executed the code to create the multidimensional dimensions and the multidimensional cube (awm dimensions/cubes), but I had some problems in the first dimension.
This dimension has the name D_DESTIN, and has the following hierarchy:
+DESTIN_DESC_H3
|
+---DESTIN_DESC_H2
|
+------DESTIN_DESC_H1
|
+---------DESTIN_DESC_H0
The name of the hierarchy is H_D_DESTIN.
The following code is the code that I used to create the first multidimensional dimension:
set serveroutput on
execute cwm2_olap_manager.set_echo_on;
execute dbms_aw.execute ('aw create ''WTESTE''');
execute dbms_awm.create_awdimension('EXEMPLO_OLAP', 'D_DESTIN', 'EXEMPLO_OLAP','WTESTE', 'WD_DESTIN');
execute dbms_awm.create_awdimload_spec('D_DESTIN_LOAD', 'EXEMPLO_OLAP', 'D_DESTIN', 'FULL_LOAD');
execute DBMS_AWM.SET_AWDIMLOAD_SPEC_PARAMETER ('D_DESTIN_LOAD','EXEMPLO_OLAP','D_DESTIN','UNIQUE_RDBMS_KEY','NO');
execute dbms_awm.refresh_awdimension('EXEMPLO_OLAP', 'WTESTE', 'WD_DESTIN', 'D_DESTIN_LOAD');
commit;
execute cwm2_olap_manager.set_echo_off;
execute cwm2_olap_manager.end_log
When I executed the code above, I got the following error:
PL/SQL procedure successfully completed.
SP2-0103: Nothing in SQL buffer to run.

I don’t know what is wrong. The ROLAP Cube is valid according to Oracle Enterprise Manager Website, and it is possible to consult its data with "OracleBI Spreadsheet Add-In"
What is wrong?

Answer 1

I executed the same code in a different user and the MOLAP Cube was created successfully.
But, I don’t know what is the privilege/role, that permits this second user to create a MOLAP cube with the package DBMS_AWM.
The privileges/roles of the first user are:
ROLES
======
CONNECT
OLAP_DBA
OLAP_USER
OWBR_EXEMPLO_OLAP
OWB_EXEMPLO_OLAP

The privileges/roles of the second user are:

Which privilege/role permits the second user to create a MOLAP cube?
