When users log on
SAP, you may want to setup a splash screen to display information about
the usage of the system and which clients are available for
which purpose. The following procedures have been adopted
successfully with SAP release 4.6Cand up.

This can be accomplished by
following these steps:
a) Use transaction SE61
b) Select Document Class 'General Text'
c) Enter name 'ZLOGIN_SCREEN_INFO'

d) edit your messages and icons
(see syntax in the example below)

Good luck!
PS: We do not give any support
if you have problems with this procedure.
You may want to check
the OSS for updated information for your release.
