Allowing Multiple Login of users in Production system

Hello,
In my office there are total 4 employes which all use SAP but they all use one username and password so it isn't possible for them to work at same time. Only one employe can work, then after he completes his task he must log-off, and then other employe logs-in and so on... So Multiple Logon option is disabled. I would like to enable Multiple Logon option but as I read it somewhere Mult.logons in productions system of users musbe set to off?
I am not sure what do do because I need to have option for employes to lgoin at the same time with one username/password.
If this is not possible is there any other way to achieve this? Also is there any way that one employe can enter/view data and other three employes can login at same time only to view data?
Any help is appreciated and <removed_by_moderator> !
Greetings,
Adi

Hello Jurjen,
I have no intention to voilate any of license agreement, I had to do it once in emergency.
@David Berry
Hi David,
There are four users in my office but I am not sure of exact total number of SAP users in my company.
@R. Voerman
Thank you very much for this information. I will try this definetly. Could you tell when I enter this parameter, then
multi_login_users option is ON, right?
@Julius Bussche
You can also assign it selectively to more users than the length of the system parameter field allows...
Hello Julious,
how do I this in transaction SU01, what do I need to change?
It's no problem form me to change this parameter but I am not sure if this is good because of security issues?

Note:
"Multiple logons of users must be set to 1 in sap production systems. This can be allowed in DEV systems. But in production it must be restricted."

  • Best way to block multiple logins/same user ?

    What is the best way to block/prevent someone from logging in more than once at the same time with the same userID?
    I was thinking to post to a database whenever a user logs in/out but then every time a user does this there has to be a database call to see if that user is already logged in. This solution doesn't seem to efficient or maybe it is.?? Anyone with a better solution?

    I'm not sure what you mean. A user will log in, the form data will be authenticated against the db data, credentials will be stored in the session if authen was a success and sent back to login page if otherwise. I am imagining that I can put a flag field in the database LOGGED_IN with Y or N. So when user successfully authenticates I can insert a Y in the user's LOGGED_IN field and when the session gets destroyed insert a N. Does this answer your question?

  • Multiple logins or user access.

    I have games and educational apps for my daughter.  I'd like to let her play on it without worrying that she will get into other apps or my email or on the web.  Is there a way to have different logins? Or is there a way to only provide access to those apps I want to be available for her?

    There is only one login.  Yu can prevent her from using the email app by turning off the account in Settings>Mail...... and then setting a Restriction to prevent changing mail settings. You can also do some other things by Restrictions.  See:

  • RFC users locked after system copy in production system

    Hi,
    BW_User,MDBTC(RFC users) system users were locked in our BI Production system at the same time system copy activity was running in the Quality system(production to quality) so as per our colleagues concern after system copy they started Quality system with out changing background work-process 0 so some jobs were triggered which were copied from production system.
    Is there any cause to lock RFC users in production system for system copy? If there is any other reason where we can check logs
    Thanks

    Hi,
    Well maybe i am wrong to analyze your problem .
    Anyway I faced this issue to in our system before and we found that one background job was running  in a system that has basically  prompting an RFC connection to another system. In the t.code SM59 and there was wrong password was put in.We just reset the password and it was worked fine.
    You can try for this..

  • Multiple logins on one computer - Different accounts, same picture...?

    Greetings,
    Since the iPhone 3.0 recently released push notifications, I decided to open an account for my wife that she could use on her iPhone. From what I understand, iChat now allows multiple logins on each computer.
    I set everything up accordingly, noted that I am the admin on this computer, my picture pops into my ichat name. If I then enable her account on the same computer, her login also pops up next to my window. This is working according to plan.
    However, if I try to change the picture on her ichat window it also changes on mine. What am I doing wrong here?
    Cheers...

    Hi,
    iChat can not display different Buddy Pics for different Buddy Lists.
    This may change with Snow Leopard.
    Click the iChat Menu and use the Feedback option and post your wish there.
    iChat can use one of 4 Buddy pics.
    You can set a Pic in the iChat Buddy List by clicking on the current one and using the edit features.
    If there is not one in the Address Book for yourself And this tends to be the one selected in System Preferences > Accounts > Your account although you can set them to be different (Three choices so far) it will default to one for the account type (A Running yellow man for AIM, A Blue Globe for @mac.com names and the Cloud for MobileMe names).
    Apple have tended to suppose that if two or more people are going to be using a Mac that there are then Mac User Accounts set up on the computer and therefore there is no issue with Buddy Pics.
    The iChat Buddy List is held on the AIM server (AIM names, @Mac.com [email protected] ones).
    Part of the process is that the local Buddy list compares this to the Address Book and Add the Real names you have entered.
    So only this name in the Address Book on that computer will show Real names if entered.
    You can Export the Address Book on one computer and Import on the other to get them the same. (Or Sync via MobileMe if you have an Account)
    You are getting in to the realms of your wife's Buddies being in your Address Book.

  • Multiple Logins

    I have a Mac Mini at home and travel with an ibook g4. I want to call home but area on ibiik to "Allow multiple Logins for this Account" is so I can't check it. Now, if I login on the g4, it disconnects the mini at home. How can I talk with my lovely wife? (The mini does allow multiple logins).

    HI Steve G,
    I am sure he made sure both computers were Logged out of AIM before cahnging the settings in iChat > Preferences > Accounts > Account info tab

  • Disable Multiple Logins isn't working quite right?

    In iChat I do not have "Allow multiple logins" checked for my AIM account. However I am having no problems logging in on my computer, and with the AIM app on my iPhone at the same time. Both can send and receive messages. Ideally I would like to have logging in with one log the other out, and I thought that's what unchecking "Allow multiple logins" would do, but apparently not? Is it for something else? Are there any other ways to get the effect I'm after? Thanks

    Hi,
    Have either of you got iChat set to Allow the messages to be sent to a Phone ?

  • Uploading mitigating controls - UAT to production system

    Dear gurus
    Before i place the issue i would like to give some background: In the Production system of Complaince calibrator we have 3 systems assigned Production, UAT and Develeopment. We are the implementation team and are not authorised to assign the mitigating controls for users in production system , therefore before going live we have assigned the mitigating controls to same set of users in UAT system in the production system of compliance calibrator. Now the region has gone live and the same set of mitigating controls needs to be assigned to same set of users with same risks to production system users.
    Issue: Now there are over 100 users and its not feasible for us to manually once again assign the same mitigating controls to the users. is there a posiibility to automate this assignment or will we have to do it manually. In case we can automate then how? in case we have to manually do it what is the best way to cover the users faster.
    Thanks in advance
    Vani

    Thanks Frank, Would you advise which would be the better editor?
    Hi Alpesh,
    If i understand correct, you mean to say that its the same table, since its the same RAR production system, but currently while adding the mitigations I would have chosen the users as mentioned in UAT system that is attached to RAR production, but how do I make it as production system? If i go by what you say, I should add the user ids as per the production backend system in the same tabel and then it will automatically pick it while running reports for production users, is that correct?

  • How to allow multiple users login to a MAC PRO without interruption?

    I have a mac pro, which runs Yosemite, (2013 module) to be used as a server. However, I have difficult to let multiple users to use the mac simultaneously.
    Objective:
        One person uses the mac directly on his desktop, while the others to login remotely though VNC from PC (win 7/Linux).
        The users have their own workspace, and they will not interrupt each other.
    What I tried:
        I created two mange accounts on the MAC.
        Account 1 was used to directly login on the mac desktop.
        Account 2 was used to login to the mac from a PC though VNC. (I also tried this from a Centos workstation with the Tiger VNC viewer)
    Problem:
    When account 2 is login, the location monitor will automatically change to that account as well. Both accounts shared exactly the same screen, mouse & keyboard actions. It is impossible to let multiple users to use the MAC pro simultaneously without interruptions.
    If I use "hdiutil attach" to mount a dmg file though SSH with account 2, the folder will automatically show in the local desktop login with account 1.
    Question:
    I read something about the "Per-user screen sharing". It says, "You can remotely log into a Mac with any user account on that computer and control it, without interrupting someone else who might be using the computer under a different login." Is it possible to do this from a PC or Linux client?
    If the problem is simply due to the poor functionality of the build-in VNC service in Yosemite, I appreciate your help to suggest some other decent VNC server for Yosemite. I know the Vine Server (OSXvnc), but I failed to install it on the mac because it is incompatible with the Yosemite.
    Does the SSH is supposed to work in this way in OSX? I mean the local account can see the folder mounted by another account though SSH.
    If any specific version of Yosemite is required to allow multiple users to access a mac simultaneously? Just as the win 7 professional allow only one user to login in at each time. But with the remote desktop server of windows, multiple users are able to use the same computer at the same time without any problem.
    If you familiar with any of the above questions, please help. Any comments and suggestions are appreciated.
    I know the best way to get the solution is to direct call the apple support. However, it is really not easy to call them. Because it always results with long waiting time and then the people pick up the phone will transfer my call to an expert who will make me to describe the problem again.
    Since I'm not interested in the technique details of all the problems, it is also grateful if you would provide a direct instruction to let me setup the computer for the purpose.
    Thanks you very much for your kindly help.

    I cannot help with the screen sharing, although I have just tried it with a RealVNC client on an iPad and it seemed to work OK.
    However on the disk showing on all users desk tops have you unchecked the "ignore ownership on this volume" check box? You can check the drives permissions with CMD i command.

  • Compiz starting with GDM allowing multiple users

    So there's no way to launch compiz and support two different sessions?

It could be used in OBIEE Delivers which enables contact information, such as e-mail addresses to be retrieved from a database and used as delivery devices in Delivers instead of having the user's manually setup their own delivery device.

  • How to see, if some user has done multiple login at the same time

    Hi,
    i'm looking for a tcode to see, if some user has done multiple login in a date-range.
    Regards, Dieter

    It is also dependent on your license type, as it is populated at logon - prior to any Z-coding option - which will cause a lockout if attempted an access that way.
    I recently found a cool way to detect DB triggers and updates - very obscure...
    However I also "move around" during support in projects and don't always want to kick myself out. I guess SAP can "work-it-out" from the various fields of the table to map the user behaviour.
    Personally I dont believe that all of such information is appropriate for public domain, as all the SAP_ALLers out there combined with the types of authentication options are not always responsible with the information either.
    Thankfully, SAP has added a "salt" to the password hashes now. They offer RZ11 login/password_downwards_compatibility as a workaround...
    Take a look in your system!

  • Receiving error message "Login failed for user 'NT AUTHORITY\SYSTEM'" every minute on server which is the mirror

    Hello,
    I have 2 SQL Server 2008 R2 machines that are configured with database mirroring (using certificates as authentication), there is no witness configured.  My issue is that the mirror server is receiving at least one of the below pared messages every
    second and filling up my sql error log quickly.
    SYSTEM is the service account user for the MSSQLSERVER service. 
    [298] SQLServer Error: 4060, Cannot open database "<databasename>" requested by the login. The login failed. [SQLSTATE 42000]
    [298] SQLServer Error: 18456, Login failed for user 'NT AUTHORITY\SYSTEM'. [SQLSTATE 28000]
    The database has a status of: Affected database state is: Mirror, Synchronized/Restoring...
    When I checking the database mirror monitor, it shows that its mirroring ok and everything has green checkboxes.
    Is there a way to stop all these errors being logged, I'm assuming this isn't normal.
    Marcus

    Yes i have faced the same issues and tried everything and nothing was using this account, system was ended up with creating few GB's sql error log files everday.. and finally i had two options, 1 -- Rebuild the instance completely 2. Change the SQL Server
    Audit settings to Only successful logins and restart the instance.. ( May be your current sql server level Audit setting is set to Failed & Successful logins..
    Remeber my server was a DR so I have changed the SQL Server Audit settings to only Successful logins.. but production servers we will monitor both... :)

  • Multiple choices for User's Profile& Preferences System Code for GSM ?

      Hello,
    I’m LauraJ and I have a question regarding users being able to see in GSM the item codes for specifications entered by other business units users.
    When this user is making a generic search in GSM for the common specifications shared by multiple facilities, on the search page he/she is seeing only the system code from its facility; the codes entered by sister facilities users for the same specification are visible only if he/she opens the spec.
    I tried to change this into User’s Profile& Preferences System Code for GSM but I can choose only one option. How can I select multiple choices for System code?
    thanks in advance!

    In GSM and SCRM, you can only select one preferred System Code. But you can create an Enhancement Request for use to allow multiple.
