Mass cancel of PO's

Dear Friends

 

We migrated some PO’s which should not have been.  All these PO’s are approved, is there any way to get rid off those PO’s? We tried using API to cancel and it is working but is there any way to purge all these orders? And also what if there are any invoices against these orders? Is there any way to cancel the invoices as well pertaining to those orders?

 

There are almost 1400 PO’s out of 10000.

 

Thanks in advance

 

Thanks

Dilip
