How can I copy a specific data value from a table, so I can paste it into something outside BusinessObjects?  For example, I don’t want to have to keep re-typing the PennID when looking up a person in SRS.

You can only do this in Webi, it is not available in InfoView:  Right click on the specific data value, select 'Copy as text', then go to your outside application and paste it.

Note: If you are not authorized to use Webi, an alternative is to export the report to Excel, then copy/paste from Excel.
