  1. hi....
    nice doc...
    can u please explain the difference between RZ10 and RZ11.

  2. Hi..Through Rz11, we can view the sap parameters default value, current value and profile parameter value. Default value means the value obtained after system setup. profile parameter value is the value present in RZ10 profiles. Current value means that value that is set for a parameter through Rz11 tcode(i.e. value set for a parameter dynamically).

    Through Rz11, we can set value for a some selected parameters and those values will be lost after restart of the application server and system again starts with values in profile.

    Through Rz10 transaction, we can set permenent values to a parameter, whose values take effect only after restart of the application server as after restart profile file parameters will be read by server.

    To summarize, through Rz11 we can set values for dynamic parameters for temporary purpose and these values will be lost if application server is restarted. If you would like to change those values permenantly, we need to set through Rz10 and values take effect only after system restart.
