SAP BO - max current connection per system

Hi Guy,

In BO CMS Authorization settings for SAP, in "Options" tab, there is a setting call "Max concurrent connections per system". By default, it is set to "10". It is for the current connections from BO to backend BW system. Let's suppose that there are 10 users are running reports that are accessing BW system to retrieve data. What will it happen if new user open a workbook in BO? Will he/she be waiting?

How can I check the current connection either in BO or BW? So, I can see if 10 is enough or not.

If I change the parameter in BO, do I need to restart the SIA agent to make it valid?

Thanks

Steven
