Hi Manoj,
the empty details in the viewer are confusing to me. I'd expect some error messages.
The SCMS_DOC_INFO seems to be o.k. Status 2 = o.k.
What happens in function module ARCHIVOBJECT_DISPLAY. This function module is called when a document should be displayed. You can try it in SE37.
Also you can set a break point and call it from OAWD. Maybe some interface parameters are missing.
Regards,
Benedikt
