Checking FAX/Email (SOST) via ABAP or Function Module

Hi.

I'm wanting to check email/fax send status for a given date using Perl SAP::RFC module.

The only way I've found so far of checking is with SAPs own SOST/SOSV but the reports behind these can only be run in dialoq mode i.e. attached to a GUI.

If I try and run via SAP::RFC I get errors to say 'GUI not attached'.

How can I check the status, similar to what SOST would show, without having to actually run the commands?
