Getting summary data in Hierarchical

Question

Hi,
I have two tables:
A. Employee Data with the following columns
EMPLOYEE ID
Org_unit_id
Salary
B. Organizational hierarchy
ID
ParentID
CompanyID
I need to get Sum of salary aggregated to each unit, their parent unit and Company level in a single Query.
Please note that organization hierarchy can be spanned to multiple levels.
Example:
Employee Data
Employee ID Orgunit ID Salary
1 101 200
2 102 300
3 201 400
4 202 500
Org hierarchy Data:
ID Parent_id Company
100 NULL 10001
200 NULL 20001
101 100 10001
102 100 10001
201 200 20001
202 200 20001
Expected result:
Company ID sum(sal)
10001 101 200
10001 102 300
10001 100 500
10001 NULL 500
20001 201 400
20001 202 500
20001 200 900
20001 NULL 900
