Yes. We can change the logo in the right-hand side of the initial screen.
The logo picture can be in any bitmap format, as long as the MIME types in maintained well.
Go to transaction SMW0 and choose “Binary data” option.
Maintain the MIME type (if you’ve not maintained yet) in menu Settings → Maintain MIME types.
Create new MIME type as you wish, with the extension of the bitmap.
For example, if your picture is in JPEG type, you can create type “image/jpeg” with the extension of “*.jpg” and “*.jpeg”.
Then create new object repository, for example Z_SAP_LOGO, and locate your own logo picture.
You still need to put a little customizing in table SSM_CUST to activate your logo.
Go to transaction SM30 and change table SSM_CUST.
Add new entries name of “START_IMAGE” and fill the value with “Z_SAP_LOGO” which is created in SMW0.
Save the table view.
Now, every time you login into SAP, your own logo will appear.
Additionally, you can adjust the logo to the window size automatically, or center it in the right-hand side.
Just put entries of “RESIZE_IMAGE” and fill the value with “YES” (center size) or “NO” (window size) in table SSM_CUST.
