SAP will contact you to open the connections for them, so that they can prepare the system before the actual session takes place. In the session, they will see if the SDCC version is good enough so that they can download the data from your system into their internal system on which they carry out the analysis. Then they see if SAPOSCOL is running and enough history data is there in ST03n for them to carry out reasonable analysis. If everything is set, a download is scheduled on your system using SDCC for a day prior to the actual session. Finally, on the day of the session you open the connections for them again and provide them with userid and password. Normally, it is earlywatch in 066 client.
