How to delete data from staging table in LTMC Fiori

Hello,

I populated some records into the staging table through file upload method through Fiori app. During simulation system identified errors and hence would like to update a new record with updated content. Though I deleted the old file and uploaded new file, system was not reading the new file / record and still showing the old record on mapping tasks step. How to remove the old record from the staging table so that I can confirm the mapping task for the new record. I couldn't see any option to delete the records.

Could someone throw some insights.

The object used in testing is the Supplier

Thank you in advance.

Regards,

Venkat
