Value Based Dimension causing Aggrega tion problems

Question

I am new to building cubes in Oracle Olap, and am having trouble with a particular cube. (I hope I get all the terminology accurate enough to describe the problem I am having). Our organization structure is hierarchical. For example, org 0001is at the top of the "tree" and has 5 children: 1000, 2000, 3000, 40000, A000. Each of those 5 orgs have children that rollup to them. The problem is that the org "tree" is uneven. For example, Org 4000 has children that go down 4 more levels where the 3000 org only has children that go to level 3. We have about 1500 total orgs in the company. The dimension table we have shows the org_number and its Parent_org. Thus, I created an org dimension in AWM and then a value_based hierarchy. I can maintain and view the dimension in AWM and it all looks fine. I can then map the org dimension in the cube and maintain it (the cube that is). The problem is that the totals for my measures (actual costs) in the cube are way too high. Any advice as to what the problem is? I have verified that every org is in the table only once and that each org only rolls up to one parent org. I should mention that costs can be incurred by any org in the structure, no matter what level the org is at. Thanks for your help.

Answer 1

Thanks for your reply. That was a helpful suggestion. I found what seems to be the problem,but don't know why it is happening. When I look at a particular leg of the Org in the cube (in AWM) I see the following totals (indented to show parent child relationship):
ORG--------------------Total
1000...................602.42
-------1030............557.48
--------------1034.....557.48
-------1060............ 44.94
--------------1063..... 44.94
When I Query the fact table I see the following totals:
1000................... 0.00
1030................... 159.05
1034................... 557.48
1060...................7,800.00
1063................... 44.94
To me, it looks like the total amount of the child is REPLACING the total of the parent. For example, the total in the cube for org 1060 should be 7,844.94 (7,800 + 44.94). Any reason why it doesn't sum correctly?
Also, the total for org 1030 should be 716.53 (557.48 + 159.05).
If you look back at my first post, I said that the overall total in the cube at the top level is way over the total in the table. That is still the case. This example that I have shown happens to be the opposite. The total I get when I query the fact table is greater than the total in the cube at this level. I hope that is not confusing.
