ADM100 Lesson: Configuring SAP Logon
Figure 6: Setting Up SAP Logon
The Server... button allows you to create a connection to a specific instance
of an SAP system. As with the Groups... button, information about the
instances that are available for selection is collected from the message
server.
With the New... button, you can create a connection to an SAP system that
need not be listed in the sapmsg.ini and services files. Therefore, you enter
all of the system information that is relevant for a logon here yourself.
The name of the host on which you want to contact an instance, and its
system or instance number is essential. The instance number specifies the
last two digits of the 4 digit port address through which the dispatcher
of the specified instance can be contacted. The first two digits are fixed,
and are 32. This means that port numbers between 3200 and 3299 are
possible. The ports 3298 and 3299 are, however, assigned to the niping and
saprouter programs by default (although this can be changed). For more
information about this, see the SAP Library for the SAP Web AS with the
search term “3298”.
You can also specify a SAProuter string for new connections to be
created. Through this connection, a SAProuter is then assigned the task
of transferring data. SAProuter strings can also be specified using aliases.
These aliases are decoded using the saproute.ini file.
Hint: If you do not want to allow users to edit the system entries,
you can use the SAP Logon Pad program.
Which files are stored where? The following list shows the files with their
possible storage locations; in the case of multiple possible locations, the
search sequence is shown:
