SAP GUI – Visualize subscreen boundaries
As part of a project, we have tried to widen the screens of transaction IW33, as only a small part of the screen is used.It is quite difficult to find out exactly how the subscreens are nested in the SAP GUI.
A setting in the “Registry” of the local computer can help here.It activates the display of the individual subscreens in the SAP GUI.
The exact procedure is described in SAP Note 324687 – Visualize subscreen limits.
The settings can be set using the registry editor, which is installed as standard on Windows systems:
Registry Editor (regedit.exe):
HKEY_CURRENT_USER\Software\SAP\SAPGUI Front\SAP Frontend Server\ReleaseDebug\ShowBorders
ENABLED = 0 → deactivate
ENABLED = 1 → activate
If the keys ‘ReleaseDebug’ and ‘ShowBorders’ are missing in the path, these must first be created manually (as described in the note).
To do this, right-click on the “SAP Frontend Server” folder and then create and name two new keys via ‘New → Key’.
The registry entries must then be created and named within the folder via ‘New → DWORD value (32-bit)’.
The variables can then be set by double-clicking on the entries.
