Hi,

Yes. It will not work in 9.0 version.

Please refer SAP Notes:

1815509 - New enhancement "License Abuse Prevention" in SAP
Business One 9.0

Symptom

Currently, SAP Business One license could be abused in several ways:

1. Different persons login to the same company (taking advantage the dual
login feature).

2. Different persons login to different companies using the same user code
(but different password).

3. In hosted environment, several customers can connect remotely to different
companies with the same Business One user and password. The abuse is done by the
hosting provider, who maps windows user to SQL DB and give the same Business
One user and password to all his Business One customers.

These scenarios impact significantly the Business One license structure.
Therefore, since SAP Business One 9.0 PL01, a new enhancement is implemented
with the name "License Abuse Prevention".

Please note this enhancement will replace both "dual login"
feature in earlier versions and "logon limitation" in 8.82
version.

Solution

Now the license manager will verify the user name together
with the 3 parameters: workstation IP, windows user and windows
session ID.

The purpose of this solution is to ensure that one user can
only connect to SAP Business One via one
single session. Once the user logins via a second session, the
first session will be locked. A session can be either a new
windows login on the same machine (with the same windows user or a different
windows user) or a login from a second station.

DETAIL:

For one Business One user, it can login successfully if all of 3 parameters
are same. It means from one session, one user can login to unlimited number of
companies and/or unlimited logins to the same company.

However, if any of these parameters are changed when the same user logins,
the system will treat it as a second session, then the first session will be
locked.

EXAMPLE:

SAP Business One user (let's call it UserA), when it logins to Business One
alone for the first time, the system already records its parameters:

a. Workstation IP

b. Windows User

c. Windows session ID

Now for the following operations:

1. UserA opens a new Business One in the same workstation and logins to
another company database: It is an existing Business One user
name. All of 3 parameters are not changed. Login successful.

2. UserB login to Business One via the same workstation: It is a
new Business One user name. Login successful.

3. UserA login to Business One via another workstation with the same Windows
user account: It is an existing Business One user name, but
parameter a and c are changed. Login
successful but the previous session will be locked.

4. UserA login to Business One via the remote connection to
the same workstation with the same Windows user account: It is
an existing Business One user name, but parameter
c is changed. Login successful but the previous session
will be locked.

LOCKED:

As mentioned above, when another session of your logged user is connected,
your current user session will be locked for all the companies, like when
pressing File->Lock Screen menu in Business One.

System message will pop up:

Your session has been locked because another session was started
using the same user ID. To continue, exit or lock the other
session.

EXCEPTION:

User "manager" is exceptional and it can
login via two sessions at the same time. This is for supporting
implementation scenario, where usually SAP consultants use "manager" account
without interrupting or taking other users' license.
