Custom Form and MAPI

[Fernando Barajas Corona]

Hi all;
 
        I have a WF scenario using template "Workflow for requisition
release", wf_req_rel...
 
        Approvers use outlook with MAPI SP and it's working well, but they
want to see the WI in another form...
 
        Is it possible using a custom form instead of sapgui... ?
 
        Which are the steps we need to follow to replace the form(sapgui)
with a custom form ??
 
 
        Any help is appreciated...
 
 
Thanks in advance.,,,
