Delete All Purchasing info record in a client

Hi everyone

I have a question about how to delete All Purchasing info record in a client.

I use SARA and object " MM_EINA " to do it.

However it just can archive the info record with marked deletion flag indicator.

Does any ways to set all purchasing info record with marked deletion flag indicator?

Or Is a report available to archive all pur. info records ignoring the deletion flag?

Tcode ME15 just can set deletion flag to one record each time. It is painful to set hundred of records.....
