SAP Note 11013 - Transporting profiles and authorizations.

Symptom

Question:
How can profiles and authorizations be transported between clients
or systems?

Solution
First create a correction using Transaction SE01.
Then call up profile maintenance: Tools -> Administration ->
User maintenance -> Profile -> Restrict work area; press ENTER,
-> Profile -> Transport. All existing active profiles are then
displayed in alist where you can select the profiles to be transported
(or all profiles). After you press ENTER, you are prompted to
enter your correction number. Press ENTER once more. The system
asks you whether all dependent objects (lower-level profiles and
authorizations) are to be included in the transport.
If you want to transport the profiles without dependent objects,
you can also include selected authorizations in the correction
(access via authorization maintenance).

Use Transaction SE01 to release the correction to a transport request.
Note # 10101 explains how you transport objects from a source client
to a target client or from a source system to a target system.

Please note: The transport overwrites profiles and authorizations
with the same name in the target system. Therefore profiles with
the same name in different systems and clients should have the same
content.
If you want to change an SAP standard profile, please first copy
the profile and then change the copy.
You can assign arbitrary names to your profiles except those reserved
for SAP, i.e., the profiles and authorizations whose name have an
underscore as the second character or the profile names SAP-ALL
and SAP_NEW... .
The SAP profiles are overwritten by every upgrade, i.e., changes
that you have made in the SAP standard profiles will be deleted.

Key word: Transport auth.
