EIS dataloads on ASO - missing data during dataloads

Question

We build are building an ASO application with duplicate member names. The member load works fine, but when I load the data, I am missing amounts so some measures are out of balance. In trouble shooting the data, I found if I load just the Agent (level 0) amounts balanced, so I changed the filters to:
1. loaded the Branch for the agent (next level in Heirarchy)- number still balanced
2. loaded the Mgmt Office for the agent (next level in Heirarchy)- number still balanced
3. loaded the Region for the agent (next level in Heirarchy)- number still balanced
But when I load all, I am out of balance. So I created 8 filters in EIS, and loaded the data in 8 steps. All the measures balance when I load in in 8 parts. Has anyone run into this issue?
Running on Windows 2003 Server 16 Gb RAM, 4 processors.
Stats from:
Essbase Input-level data size 10016
Dimension 13
Attrib Dim 3
Measures 32
Largest Dimension 16333 members 12842 stored
All other Dimension <50 members <50 stored
(4 Dim <10 members, 4 Dim bwtween 10-20 members, 3 Dim between 33-34 members, 1 Dim with 44 members)
Number of input cells 862292
Rows from SQL 264519 (4 months of data)

Answer 1

I am loading all the data for that filter and below, so the:
a. first load for just a single agent and check the data.
b. Second load was for the branch with that agent and all other agents in that branch
c. Third was for the Mgmt Office with the same agent and all other agents and Branch in that Mgmt Office
4. Fouth load was for the region with the same agent and all other agents, Branches, and Mgmt Offices in the Region.
Each of those data loads were ok, but when I loaded the Countrywide data (All 8 regions) in one single dataload then I had problems with balancing.
