Following the link:

I have done the following:

IBM Cognos Administration --> System ---> Set Properties (System Drop Down)  --> Settings --> Advanced Setttings --> Edit

Added: Paramter: RSVP.CSV.DELIMITER   Value: ,

I have waited (way more than 30 seconds) but reports still run as Tab delimited.

Are there any other parameters I need to set?
Do I need to restart services/servers for this to take effect?

Any other thoughts would be greatly appreciated.
Thanks in advance,
Adam.
