What does the file name need to be to get the View Report action to appear on Articles? This is working for incidents with the file name "Incident.rpt" but I cannot get the action to appear for articles with the file name "Article.rpt". The report does work in Console, so I don't think it's the report itself.
I don't think Service Portal was ever designed to provide that functionality unfortunately. However, the new Self Service product based on the Web Access platform as well as the existing Web Desk application should both be able to provide the ability to print a report from most windows from 7.4 onwards. 7.4 is due to be released later this year.
