Questions: What are the maximum number of sessions per User in SAP?
By default the maximum no. of windows which one can open in SAP for that system is 6. So, in essence a user can open 6 sessions in 4.7x.
Like, one set this values in rdisp/max_alt_modes parameter then he can change this parameter using RZ10 in instance profile and use extended maintenance for changing this.
Most of the companies prohibits these no. of sessions but not increase it since they can result unecessary load.
There are some parameter that doesn\'t need a restart inorder the changes to take effect.
My suggestion is kindly review the parameter configuration and determined this if it is dynamic or not.
Dynamic means once you restart the system this will revert back its original value.
If it is not dynamic then, this require a restart inorder the changes should take effect.
