[otrs] : using the ITSMChangeDelete.pl procedure

Hi I'm testing OTRS ITSM Change Mangement to implement a change management solution at a italian customer site.Now, after some testing creating change requests, workorders and so on, I would to clear the configuration without 'dropping' the database and re-create it from scratch. The problem is around the lack of 'Delete' function for Change Request items. I discovered into the bin directory a *ITSMChangeDelete.pl* module and I'm wondering if I can use it as a Generic Agent operation. I'm a newbie with perl language and I have some difficult to read the code and understand how to use it ( what parameter, etc.). Has anyone used that procedure or know some details how to use it? thanks -- Stefano Boccanera
