How to create solved fact table and corresponding cube

Question

Hello,
I want to create cube with solved fact table. It means, i need to feed data for higher levels of dimension also from fact table instead of aggreting from base level.
I am using star schema and AWM 10g R2 for creating cube.
If anyone knows how to do this, i would be very benificial.
Thanks

I have generated parent child script using cwm2_olap_pc_transform.create_script. After running this generated script, it has created 3 table/view.
My Base Parent Child table is like this:-
drop table PARENT_CHILD;
create table PARENT_CHILD (PARENT varchar2(30), CHILD varchar2(30));
insert into PARENT_CHILD values ('Eligible', 'Compliant');
insert into PARENT_CHILD values ('Eligible', 'Non-Compliant');
insert into PARENT_CHILD values ('All', 'Eligible');
insert into PARENT_CHILD values ('All', 'Ineligible');
insert into PARENT_CHILD values (null, 'All');
After running generated script thru cwm2_olap_pc_transform.create_script, it has created :-
Table - PARENT_CHILD_SOLVED
View - PARENT_CHILD_SOLVED_view , PARENT_CHILD_view
This script also inserted data in above table/view. (5 rec in each). Table/View structure is like this:-
SQL> desc PARENT_CHILD_view
Name Null? Type
GID NUMBER
CHILD1 VARCHAR2(30)
CHILD2 VARCHAR2(30)
CHILD3 VARCHAR2(30)
Data:-
0 All Eligible Compliant
0 All Eligible Non-Compliant
1 All Eligible
1 All Ineligible
3 All
SQL> desc PARENT_CHILD_SOLVED
Name Null? Type
GID NUMBER
CHILD1 VARCHAR2(30)
CHILD2 VARCHAR2(30)
CHILD3 VARCHAR2(30)
Data:-
0 All Eligible Compliant
0 All Eligible Non-Compliant
1 All Eligible
1 All Ineligible
3 All
SQL> desc PARENT_CHILD_SOLVED_view
Name Null? Type
GID NUMBER
SHORT_DESCRIPTION VARCHAR2(30)
LONG_DESCRIPTION VARCHAR2(30)
CHILD1 VARCHAR2(30)
CHILD2 VARCHAR2(30)
CHILD3 VARCHAR2(30)
Data:-
0 Compliant Compliant All Eligible Compliant
0 Non-Compliant Non-Compliant All Eligible Non-Compliant
1 Eligible Eligible All Eligible
1 Ineligible Ineligible All Ineligible
3 All All All
I tried to create dim and cube based on this. I am not sure whether its correct or not! Though validate_dimension API call shows that it is valid.
Script for Dim:-

My Fact Table is :-
DROP TABLE HCP_PC_FACT CASCADE CONSTRAINT;
CREATE TABLE HCP_PC_FACT (
SHORT_DESCRIPTION VARCHAR2(30) NOT NULL,
GID NUMBER NOT NULL,
CHILD1 VARCHAR2(30) NOT NULL,
CHILD2 VARCHAR2(30) ,
CHILD3 VARCHAR2(30) ,
MEASURE_COL NUMBER NOT NULL);
Data in Fact Table:-
insert into HCP_PC_FACT values('Compliant',0,'All','Eligible','Compliant', 100);
insert into HCP_PC_FACT values('Non-Compliant',0,'All','Eligible','Non-Compliant', 200);
insert into HCP_PC_FACT values('Eligible',1,'All','Eligible',null, 300);
insert into HCP_PC_FACT values('Ineligible',1,'All','Ineligible',null, 400);
insert into HCP_PC_FACT values('All',3,'All',null,null, 500);
I am not sure how to create level, level attr, dim attr for such dim.
All CWM2 validation API shows that my all dims, cubes are valid but when I try to create presentation thru JDev it hangs after selecting Parent-Child Measure.
Any complete working exapmle will be helpful.
P.S. One more query I have can we have one solved and one un-solved dim in the same cube/measure?
