How to Disable Multiple Logins

To disable multiple user logins within the same client implement this parameter in the instance profile:
login/disable_multi_gui_login = 1

If you do not use this parameter in your system, users have the ability to ignore the warning window at the time they try to login to the same client. Activating this parameter in your system will make you look good if you get audited.
In case you’re wondering how to allow multiple logins for certain key users you can implement parameter login/multi_login_users. You can list the user IDs that should be ignored if the parameter above is active in your system.

About Me, established in 2008 September with a purpose of sharing SAP related information and materials, owned and managed by me, Y. Z. MERCAN

I have studied Industrial Engineering at Marmara University in Istanbul, TURKEY. It was in 2008 summer, I have been interested in SAP during my 60 days training at a Lux Furniture Manufacturer firm, B&T Design, which I’m still working at now. Lucky of me, the firm was on a Go Live phase during my training and i have attended in some end-user training meet ups, also taken on tasks before and after system Goes Live. So my SAP knowledge is reasonably limited compared to consultants, considering their project experiences. Although my company had succesfully completed Live Phase, since 2011 only Financial Accounting module managed to continue using SAP ERP. Production Planning, Materials Management, Sales and Distribution modules discontinued to be used in SAP.

Most of the information and materials distributed here are collected from other SAP related sites, where i daily follow, read and try to understand. Though being busy with my work, i try to update this site regularly with information for everyone who are interested in SAP.

I hope you always enjoy at
