Hi Rahul,
Can check at SMQ1,LBWQ,RSA7 have any records for your data source?
if yes then run delta info pack multiple times and load data tin BW Qua.
Once you see 0 count at RAS7/SMW1/LBWQ for your data source then again delete and refill set up tables thru OLI9BW. After tht you can check records for your setup tables at SE11 or NPRT or RSA3 thru extraction.
Lets know the result.
Thanks
