Wrong entry of date while uploading time data in infotype 2011

Dear Experts,

We upload the excel file containing date and clock in (P10) and clock out(P20) through a custom program to infotype 2011.The end user has uploaded the excel file with wrong dates for a payroll area.How do we delete the records so that we can upload the time data once gain?

There are around 500 records uploaaded with wrong dates.Do we have any Tcode to delete the wrong data?

Thanks in advance

Regards
