Why there aren't many record in 0FI_AR_4

Hi everyone,

i check the extractor 0FI_AR_4 in ERP Production system with the setting:

Request ID: Test

Data records: 999999

Display Extr.Call: 9999

Update mode: F

but there are only 40.000 records. i think there is something wrong here because our system has hundred of accounting post everyday, and we used the System more nearly one year.

Do you know what i did wrong here?

Thanks
