sapbi_rig_cp_copy_clipboard and sapbi_rig_cp_paste_clipboard are used. After migrating to netweaver 7.5 the copy&paste does not work any more in IE browser when we are in Portal context. It is still working when we execute the webtemplate directly. Does anyone have an idea about the reason for this behaviour or a solution?
Can you check if the document mode is different when you are accessing in Portal context than executing the web template directly.
Second, please check if you are getting any errors in the console using developer tools in IE.
This should shed more light on your issue.
