Reprocess IDOC with the same user

Hi,

Inbound IDOCs can be reprocessed from BD87 but they are reprocessed "online", with the user you are logged on.

Is there any way to reprocess the IDOCs with the same user (communication type user) they were originally posted?

We are testing the authorizations of this communication user, so we need the IDOCS to be reprocessed with the same user...

Thanks in advance,

Jon
