Shaik,
What is the final data you are seeing in the DSO? It should be the right numbers..
The delta type of 0BBP_TD_SC_1 DS is based on the type ‘AIMD’ (after images with deletion indicator via delta queue).
Check in your change log table and see how the records are updated in the DSO.
Check in SCN, there are more documents explains about the delta types .
Hope this helps...
