Sorry I was away,
We migrated 10G forms to 11g also Winword 2003 to Winword 2007
It's erroring at this point
mm_obj := client_ole2.get_obj_property(template_doc, 'MailMerge');
Failing ---> client_ole2.set_property(mm_obj, 'Destination', 0); -- 0 is value of constant wdSendToNewDocument
Failing --->client_ole2.invoke(mm_obj, 'Execute');
Not able to read or open document use to work in previous version.
