Regarding Data Mismatching

Hi gurus,

The Scenario is: Iam extracting data from CRM to BW in both sides Iam using ODS, and every time Iam using initial loads i.e deleting the data every time and loading the fresh data, but I got data mismatch between BW and CRM. The CRM records are lessertham BW records. Can any body give me the possible reasons and solutions for this.

Points will be Awarded.

Thanks&Regards,

Naren.
