The entire 192.168.x.y space is reserved for 'networks not connected to the internet'. Meaning it's private space you can use however you want - your own private island.
What you have bumped into is two islands that think they have the same names.
So what the SAP people were telling you was to change the name of your island. Which is basically the x. It can be ANY number from 0 to 255, but 0 and 1 are the most commonly used.
Why do you have to do all of this? So that when you fire up your VPN connection to SAP, your PC can tell the difference between 192.168.1.y and 192.168.2.y - different x's are different islands...
Changing this is a slightly tricky process, because as soon as the livebox router accepts the change, you will lose your connection.
In the livebox configuration pages you need to look for ANYTHING that has that 192.168. address. Sometimes the router's address and the DHCP range (these are the addresses it will give out to your computers) are on separate pages.
Change the DHCP range first - tell the livebox to give out addresses on the new island.
THEN change the livebox address.
Then you need to have each of your PCs change it's address. There are two ways - BFI and fancy. Me? Go for Brute Force and Ignorance. Just restart each of them.
As they come back up, they will ask the livebox for an address and get one in the new range.

>> I tried this in the Livebox
OK did you change the DHCP scope on the livebox OR change your CLient PC's IP addresses too - cause just canging the Livebox from 192.168.1.1 to 192.168.0.1 without doin anything else would cause...
>>everything stopped working, internet access of any sort on desktop and laptop.
