Record count difference between PSA and WDSO !!

Hi Folks,

I have been loading data from2LIS_02_ITMextractor to a Write Optimized DSO.

After the load, I found that the record count is showing a huge difference. 65 Million records in PSA and 33 Million records in WDSO.

DSO was empty and we have loaded all requests as " Request by Request ".

I compared the number of requests between PSA and DSO. All the requests from PSA were loaded except the requests in PSA which says

" NO data Exist in PSA".

1) There is no Filter in DTP

2) No Routine

3) Allow Duplicate Records is Checked

4) Checked with record count  based on Document Date. There were some records missing.However Im wondering I see all the request being loaded to DSO.

5) Transferred and Added records shows same on all the requests in DSO.

Please assist with this issue.
