Troubleshooting and Limitations for SAP

This section describes troubleshooting and limitations for SAP GUI and SAP-Web protocols.

General SAPGUI limitations

  • For LoadRunner users: If a business process in SAP GUI 7.30 includes selecting an item from a Combo-list, the business process may not run properly in LoadRunner versions 9.52 and higher.

    Workaround: Add the path of the SAP GUI installation folder to the Windows PATH environment variable.

  • Recording is not supported for the SAP GUI Security dialog box.
  • Recording is not supported for standard Windows dialog boxes (for example Save or Open) which are opened from the SAP GUI client.

  • If you encounter a warning during SAP GUI recording: "Sizing conflicts exist on the screen…" it may affect replay.

    Workaround: Disable the warning in the SAP GUI application:

    1. Click the right-most button on the SAP GUI toolbar (or click Alt+F2) to open the Customize Local Layout screen.
    2. Select the SAP Internal sub-menu.
    3. Clear the Enable dialog box for screen size check box.

I was able to record a script, but why does replay fail?

In LoadRunner, make sure that the LoadRunner Remote Agent is running in Process mode. Service mode is not supported. For more information, see Run SAP GUI Scripts from the Controller.

Why were certain SAP GUI controls not recorded?

Some SAP GUI controls are supported only in their menu or toolbar contexts. Try performing the problematic task using a different means—through a menu option, context menu, toolbar, and so on.

Why can't I record or replay any scripts in VuGen?

  1. Verify that you have the latest patch of SAP GUI 6.20 installed. The lowest allowed patch level is patch 32.

  2. Make sure that scripting is enabled. See Configure the SAP Environment.

  3. Verify that notifications are disabled in the SAP GUI for Windows client. Click the Customizing of Local Layout button or press ALT+F12. Click Options and select the Scripting tab. Clear both Notify options.

What is the meaning of the error popup messages that are issued when I try to run the script?

Certain SAP applications store the last layout for each user (such as which frames are visible or hidden). If the stored layout was changed since the script was recorded, this may cause replay problems. For Example, in the ME52N transaction, the Document overview Off/On button will change the number of visible frames.

If this occurs:

  1. Navigate the transaction to the same point as it was during recording, before starting replay. You can use the Snapshot viewer to see the layout in which it was recorded.

  2. Add statements to the script that bring the transaction to the desired layout during replay. For example, if an optional frame interferes with your replay, insert a verification function that checks if the frame is open. If it is open, click a button to close it. For verification examples, see Enhance SAP GUI Scripts.

Can I use the single sign-on mechanism when running a script on a remote machine?

No, VuGen does not support the single sign-on connection mechanism. In your SAP GUI client, open the Advanced Options and clear the Enable Secure Network Communication feature. Note that you must re-record the script after you modify the Connection preferences.

Can VuGen record all SAP objects?

Recording is not available for objects not supported by SAP GUI Scripting. See your recording log for information about those objects.

Are all business processes supported?

VuGen does not support business processes that invoke Microsoft Office module controls, nor those that require the use of GuiXT. You can disable GuiXT from the SAP GUI for Windows client Options menu.

When I go to the Auto Logon node of the Recording Options, why is the list of server names empty?

This sometimes occurs when using SAP GUI Client 7.20. To resolve this issue, copy the saplogon.ini file from %APPDATA%\SAP\Common where %APPDATA% stands for the environment variable specifying the Application Data folder located directly below the user profile folder. Paste the file to the %WINDIR% folder (C:\Windows).
