Inorder to start scripting the SAP applications using the Loadrunner tool, we have to enable the scripting mode available in the SAP application apart from the normal script enabling setting.

Please use the TCode – RZ11

Navigate to the page it allows and change the settings to ‘FALSE’ for the below mentioned parameters.

a. sapgui/user_scripting_set_readonly and set the value as “FALSE”
b. sapgui/user_scripting_force_notification and set the value as “FALSE”



In Loadrunner script, we use block size per vuser for using the huge range of unique values in a parameter. But during the test, if the execution failes inbetween its very hard to re-allocate the block size again by checking the unused values. In-order to solve this issue, we can use the LR_ADVANCE_PARAM function in loadrunner. Please find below the usage format to implement this.

int x,y,v,i;  // declare these variables as integer
v=atoi(lr_eval_string(“{VuserID}”));  // get the VuserID and store it in v
i=atoi(lr_eval_string(“{ItNum}”));  // get the Iteration number and store it in i
 x=v;  // For the first iteration, x = VuserID
 x=6;  // For the second iterations onward, x = No of Vusers  + 1 (assuming Vusers = 5)
lr_advance_param(“CreatedCustID”);  // parameter file name (keep settings as Sequential Once)



return 0;

Machine A : PC which you are using to active remote desktop connection in another PC

Machine B : PC for which remote desktop connection has to be activated.


 Step 1:

From Machine A :  Goto Start -> Run -> regedit. Open the Registry window of Machine A.

(Note: User ID logged in Machine A should have ADMIN rights in Machine B)

Step 2:

Click “Connect Network Registry“

Step 3:

Enter the computer name of Machine B, for which we have to change the settings and Click “OK”


The destination machine (Machine B) will be connected with our current logged in machine (Machine A).


Step 5:

Goto the below mentioned path and change the fDenyTSConnections to “0” and click “OK”.

 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services

 Step 6:

After doing the following changes, right-click the remote machine (Machine B) name and click Disconnect.

(NOTE: If suppose the above mentioned registry value is not found, then create a DWORD parameter with a value ‘0’.
