This article answers following queries :
- What is a SAP parameter?
- Different types of SAP Parameters?
- How to identify whether a parameter is dynamic or static ?
***************************************************************
In SAP, parameters are used to set the configuration and define the functionality of an sap system like number of workprocesses, buffer size, locktable size etc.
Basically there are 2 types of parameters :
- Static
- Dynamic
Static are the parameters those won't take effect immediately the value is set. Restart of an sap system is required for them to take effect.
Dynamic are the parameters those will take effect immediately in the run time. Restart of an sap system is not required for them to take effect.
Parameter can be differentiated whether it is dynamic or static by checking in RZ11 transaction of SAP.
In Rz11, type the parameter and display it. In the screen , there will be a check box with description as "Dynamically switchable". If that check box is ticked, it means that it is dynamic parameter and value can changed in run time without restart of the system. If it is not ticked, then it is static parameter and it needs restart of a sap system for the changes to take effect.
In latest version SAP systems also, we can verify this through RZ11 tcode. Output might be bit different as shown below :

Hi Durga,
Can we change Dynamic parameter value using Tcode RZ11?
Thanks
Ravi
Hi Ravi,
Yes. Dynamic parameter value can be changed using RZ11 tcode.
Hi Durga,
I can not change values in rz11 . It has only display button.
Thanks
May be the parameter you have selected is static parameter.
So, to change static parameter value go to RZ10.
Hi Durga,
can you please tell me some dynamic parameters. becoz
i have checked in rz11.........>display....>dynamic swithcable check box......>but i did not find any dynamic parameter yet..mostly static parameters are there...
thanks®ards

rdisp/max_wprun_time is dynamic parameter..
Please find below some dynamic parameters:
rdisp/max_wprun_time
rdisp/TRACE
rdisp/gui_auto_logout
rdisp/j2ee_start
rdisp/keepalive
rdisp/max_priv_time
rdisp/max_alt_modes
rdisp/wppriv_max_no
ThanQ
Hi Frnd, You can only change dynamic parameters through Rz11. If it is static parameter, you have to change it through Rz10 profiles.
We can check a parameter is dynamic or static in Rz11. If "Dynamically switchable" checkbox is ticked in Rz11 then that parameter is Dynamic otherwise it is static.
can u post some of static parameters
hi sir i cant able access any tcode to a user its displaying not autorised to use tcode
Guess the user you using don't have roles assigned for the corresponding Tcodes you are trying.
Go to SUIM & compare the user roles with a well working user profile & assign all the missing roles through SU01.
Static Parameters:
rdisp/wp_no_dia
rdisp/wp_no_btc
rdisp/wp_no_vb
rdisp/wp_no_vb2
rdisp/wp_no_enq
rdisp/wp_no_spo
hi,
table TPFYPROPTY contains all dynamic switchable system parameters

super blog
Hi Durga,
I understand we can change,
Static parameters via RZ10
Dynamic parameters via RZ11.
But If we change a dynamic parameter, and if sometime later the SAP system is restarted...will the changed dynamic parameter remain same in the system ? or do we need to make changes again ?
I believe dynamic parameter changes remain reflected as long as the system is up and running.
Kindly enlighten me.
#Your blog is super awesome. Amazing !
Hello Durga,
Your document is very useful for me, can you send me system refresh and system copy concept.
Hi Durga
can u please tell me aboutnumber of workprocesses, buffer size, locktable size ?
Akash, the change wont remain the same with Dynamic Parameter, you need to make the changes again...
very nice!thanks...........
Really Superb information. Thank you so much Durga Sir.
in 2018 we still learn thanks to you Durga!
How can we distinguish between static ad dymanic parameters of an abap system??any fm or tables we cn depend?or os level cn we know??
How to distinguish between static ad dymanic parameters of an abap system??any fm or tables we cn depend?or os level cn we know??
from which tcode we can check the changed parameter?
Recent changes in parameter can be checked using TU02 tcode.
