If an external RFC program starts a communication that displays screens
(lists, graphics and the like), a 'sapgui' has to be started on the
local machine.
This program must be installed on the machine. The procedure for this
depends on the platform being used.
Windows 3.1, Windows 3.11:
Under the 16-bit version of Windows, this functionality is not
available.
Windows NT and Windows 95:
A 32-bit 'sapgui' must be installed on the machine. (not a 16-bit
version!)
The program can be installed anywhere because it is found using the
Windows registry. 'sapgui' registers itself there automatically.
Unix (Motif):
The 'sapgui' program is found by searching in the normal SAP tree (
/usr/sap/.../SYS/exe/run ).
If you want to look for 'sapgui' somewhere else, you can specify
another path by setting the SAPGUI environment variables. This is only
recommended for test purposes however.
Include for RFC GUI communication problems.
