Multi connexion with an unique account on SAP R3 ?

Hello everybody,

I begin a new mission in AS (Application Support) and my new colleagues tell me they take a lot of delay because they have only one account SAP R3 (For example PGI).

My question :

I worked on SAP BW and in order to connect many users simultaneously, i used to connect them via Browser 3.X SAP BW.

So dear colleagues, do you know if a similar browser for SAP R3 exists ? In this way, i will be able to connect all my team even we have only one account...

Many thanks in advance for your return.
