Basis Administration Questions Answers
What is th difference between Sap lock and database lock?
A SAP lock is named enqueue lock, the enqueue is on a much higher level, e. g. a complete sales
document is locked there whereas in the datbase usually only row locks exist. Since SAP runs on more
database than Oracle (thanx god) one needed to have a mechanism, that is database independent and
on a higher level.
What is the diff between clients 000 and 001?
Client 000 is the SAP source client, client 001 exists only on certain installations (e. g. solution Manager).
I would like to know is there anyway to transport roles from Production to Development or Sandbox.
Goto PFCG and enter the role which you want to transfer to other system. goto utilities->Mass download
it will ask the path where to download/save that role on local desktop give the location and save it. Next
logon to the system where you want that particular role.
PFCG-> Role -> upload.
Give the path where the role is saved. it accepts and generates successfully.
What is the need of having Development system?
To develop and custamize SAP to companies requirement. say if you dont have DEV, after go-live(started
using SAP (PRD}) if you want to do some changes to application, you cannot do changes directly
toPRD server, which may cause problem the PRD server live data. so you do the required changes
on DEV first and test them on QAS, if it works fine
them transport the same to PRD.
Difference between Application server and Central Instance?
AS: Is just a dialog instance.
CI: Is Dialog instance + Database Instance.
What is Transport domain and Domain controller?
TD: is the collection of transport controller, trans directory and all other systems in the group.
TC: A system which will have trans directory, and in which the total landscape is designed and
maintained. in stms you can see all these.

What are SNOTES ? How to apply them in SAP ?
The name of the transaction is SNOTE. A note in general is a hint, documentation, error/bug description
and may contain code corrections, that are applied with the transaction SNOTE.
What is OSS ?
OSS is the old name of the nowadays sapnet which contains everything you need to run SAP a
program, patches, installation/upgrade documentation etc.
What are different modules used like EP, XI, CRM ,BW, etc?
Those are not different modules but different products.
EP = Enterprise Portal
XI = Exchange Infrastructure
CRM = Customer Relationship Management
BW = Business Warehouse (that is the old term), its now call BI(Business Intelligence)
What is the correct use of SPAM, SAINT, SPAD and SPDDtransactions. When should we use
each?
SPAM is for installing support packages, SAINT is used to install new addons. SPAD is for creating printers
(I assume you meant SPAU) and SPDD is for adjusting modification to dictionary objects.
Is it possible to update Support Release packages from OS level?
Noyou can import them but the full process will require additional steps the tools tp and R3trans
are not aware of. The way is to useSPAM - but SPAM has the possibility to schedule those imports in the
background.
After doing any Support Package update in SPAM, are there any further steps to carry out for
this update to take effect?
No, they are active immediately.
1. Why do we require a support package and why it is not incorporated with the new version
of SAP R/3?
2. What are add-ons and why do we require add-ons?
3. What is CRT and why we require it?
4. Who should decide which patch should be applied and when?
Support packages are a collection of fixes that have come out after the official release of an SAP software
solution.
Notice, though, that some support packages are preloaded with the system. R/3 Enterprise SR1 is a good
example of that.

An add-on is a component that can be loaded into an SAP software solution.
Examples: PI, PI_BASIS, SOA 1.0 (CGVMIC).
The CGVMIC is the Management of Internal Controls add-on, which is part of the Sarbanes & Oxley
Compliance Tool. New SAP releases come with some add-on preloaded, too. PI (Plug-In) is a good
example. It's used to exchange data with other applications such as BW and APO.
A CRT (Conflict Resolution Transport) is used when you have installed an Add-on and Support Packages
that conflict with each other.
Who decides about what patch should be applied and when? That's a good question. The answer is: You,
the customer.
I have one question about the SAP R/3 architecture: What distinguishes BASIS from the
Application Server? What is the role of Basis doing vs. the role of an Application Server? How
are these two linked & finally are ABAP/4 programs interpreted or compiled or both? Please
give me an insight into this.
Basis is part of the application server. But, think of Basis as the foundation of the SAP system. "Basis" hasto do with the installation and configuration of components that make the system work. About the
ABAP/4 language: programs are compiled to a program code that runs interpretively. The compilation
process is referred as "generation".
I'm updating my users with their correct User Type for the User Audit. Is there any listing
that identifies which tcodes are for which User Type? (Example: MM03-Informational,
MM02-Operational)
As you know everything is in R/3 tables.
So, you can get a list of "users by type" by querying
table USR02.
The field 'USTYP' indicates the type of user
(Dialog, Background, CPIC).
Once you get a list of users by type, you can use
transaction SUIM to get the list of transactions
assigned to users.
After running SUIM, select Transactions->Transaction Lists
According to Selection With User, Profile or Object->Executable
for user.
You can create your own SQL script to get everything in a
pretty automated way.
Tip: declare cursors
To help you out, see the following SQL queries
(which you can then improve by declaring cursors).

-- This query lists all user accounts that are type Background
in client 400 select * from USR02 where USTYP='B' and MANDT='400'
-- This query lists all activity groups in client 400 assigned
to the user
JOHNDselect * from AGR_USERS where MANDT='400' AND UNAME='JOHND'
-- This query lists all transactions assigned to
activity group 'AP_CLERK' in client 400
select TCODE from AGR_TCODES where MANDT='400' and AGR_NAME='AP_CLERK'
I'm confused about what Basis administration entails. Does it involve the J2EE and ABAP
engines? Please help me sort out my confusion.
Yes, Basis administration does involve the J2EE and ABAP engines, but not necessarily both at once. The
most common is the administration of the Web Application Server (Web AS ABAP system). The J2EE
applies to environments where Web development takes place.
As the Basis (technical) administrator you need to install, configure and maintain just about every aspect
of the system architecture. For information about J2EE please visit this link:

I am a new Basis administrator, and our systems are:
* SAP R/3 4.6C ( support patch: KA47, KB47, KH47 and KE84)
* Kernel 4.6D (Support Patch Level: 988)
* Solaris operating system is 64-bit, and Oracle database is 32-bit.
My questions:
1. How can I find out if our SAP kernel is 32-bit or 64-bit? I found only saposcol file is 64-bit,most of the files are 32-bit.
2. Do I have to download both DB-independent and DB-dependent files in order to upgrade
our SAP kernel?
3. Do I have to download all files in DB-independent and DB-dependent into our system? Or
just some files:
DB-independent: dw 1969, R3trans 1953, SAPEXE 1747, SAPEXE 1805, SAPEXE 1883,
SAPEXE1913 and tp 1967. DB-dependent: SAPEXEDB, SAPEXEDB 1805, SAPEXEDB 1883, and
SAPEXEDB 1913).
Run "disp+work -version". If you do NOT see anything saying, "compiled with 64-bit libraries," then your
system is running the 32-bit R/3 kernel version.
Also, I encourage you to take a look at SAP Note 192822 titled, "FAQ: 32-bit/64-bit R/3-Oracle."
I am going to quote a section of this note for you:
"For all current releases, the patches are stored in the SAP service marketplace
http://service.sap.com/swcenter_3pmain . After choosing Oracle, you have the option to go down the
oracle 32-bit or oracle 64-bit path. Please note that in order to decide which of the two to choose the

only thing tht matters is what bit version your Oracle software is. No matter whether your OS is 64-bit; as
long as your Oracle is still 32-bit you would go down the Oracle 32-bit path."
2. Yes. You need both. Otherwise, the system will not work properly or won't even start at all.
3. You need to download the latest versions or at least one version before the last one.
In the example above, you should download these files: DW_1969, R3trans_1953, SAPEXE_1913,
TP_1967 SAPEXEDB_1913 Then, you need to decompress each archive (.SAR) file using SAPCAR -XVF.
I would like to know which users have access to particular transactions. Is this possible?
Yes. There are several ways.
I think the easiest one is for you to run transaction /nSUIM. In this transaction (User Information
System), drill down to:
Infosystem authorization -User -Users by complex selection criteria -By transaction authorizations
Finally, enter the transaction in question and execute.
If you are running R/3 4.7, you can also run transaction /nPFCG.
Some of our users are not able to execute some transaction codes, eventhough the required roles are granted. How to troubleshoot?
Follow the below mentioned steps to identify the root cause:
Check if there is a user comparison issue. (The role name will be suffixed with Red light, instead
of green)
Check the object S_TCODE existence in the authorization object of that particular profile.
Check SU56 to know the objects/values available for the user.
If there is an issue with the 1st mentioned point, simply go to Profile Generator and perform a user
comparison, which will adjust the user master record. If the issue is with 2nd, you need to regenerate the
profile.
Incase, if you find that some of the objects are not loaded properly in SU56, you need to identify the # of
profiles assigned and ensure that they are below 312, as you cant assign more than 312 profiles to a
SAP User ID.
If the issue happens even with very few profiles, verify the Number of authorizations in User Buffers value
in the Instance profile. The value for Auth/auth_number_in_userbuffer parameter can be increased.
The size of the buffer must always exceed the maximum number of authorizations as authorization
checks are made only against those in the buffer.

The default value is 800, but this can be set to a value which is between 12000.
Other references: OSS notes 84209 and 75908
I am unable to login to SAP using SAP* user ID in the newly created client.What is the problem?
This issue happens if the login/no_automatic_user_sapstarparameter value is set to 1 in the Instance
profile.
Change the value to 0 to enable SAP* login.
Prior to version 4.0 this parameter waslogin/no_automatic_user_sap*.
How to restrict the users from opening more SAP sessions?
rdisp/max_alt_modes parameter should be added in the Instance profile. The default value of this
parameter is 6 and restriction should be done based on the performance of the system, number of users
etc.
How do you change the default SAP GUI client number in the initial screen?
login/system_client parameter should be added in the Instance profile. The default value is 000.You
need to make the change, save the instance profile and activate it.
How to restrict users from logging in to SAP from multiple systems?
login/disable_multi_gui_login parameter should be added in the Instance profile and the value should
be set to 1. By default it is set to 0, which will allows logging in from multiple systems.
This parameter is set to 1 in most of the Production environments. You can see the current settings in
RZ11.

What is GuiXT?
GuiXT is a standard R/3 tool used to personalize SAP screens using scripts, without changing the
underlying ABAP or business logic. GuiXT is compatible with R/3 releases from 3.0 to 4.7, SAP ERP
Central Component (ECC), and SAP NetWeaver Portal. You can apply GuiXT scripts to all SAP
transactions and implement company-wide or user-specific settings on your system. Traditional IMG
customization (transaction SPRO) is not required; you configure GuiXT settings in the SAPGUI
installation screen, which resides in your front end.

What are the various system profiles, and how to set the parameter values?
SAP has 3 system profiles:
Start profile
Default profile
Instance profile

Many of our users are experiencing CALL_C_FUNCTION_NO_AUTHORITYABAP dump. How can we resolve this issue?
The AUTHORITY_CHECK_C_FUNCTION is a function module which can be used to check the
authorizations required to execute an ABAP program. This is mainly used by the ABAPers while coding
programs that require critical authorizations to identify the access required by the users to execute the
program.
The CALL_C_FUNCTION_NO_AUTHORITY ABAP dump occurs if there is an issue with theauthorization. Verify the ABAP dump to identify the exact program and function module where the error is
generated. Following is an example error:
The termination occurred in the ABAP/4 program "SAPLXTRK " in
"GET_APPLICATION_TIMEZONE".

How can I give access to a group of printers?
The authorization object S_SPO_DEV can be used to give authorization to a group of printers. In the SAPUser menu, access to only 1 printer can be provided to the users. However, if multiple printers access is
required, the authorization object S_SPO_DEV can be included in a role and mentioning the values.
For example, if A* is mentioned, user will get access to only A* printers in the SAP environment. If access
to B* printers needs to be given to a seperate set of people, another role can be created with this
limitation.

What is the difference between V1 and V2 update?
In SAP, the update process will be performed in several steps. The time-critical part of an update is called
a V1 update, and the non-time-critical part is called as V2 update.
The V1 update will be handled by the UPD work processes (UPD: Update process for making V1 (time-
critical) database changes) and the V2 will be handled by the UP2 work process (UP2: Update process
for executing V2 (not time-critical) database changes).
To view the status of these updates, use transaction SM13. However, if you see any failed updates, find
out the root cause and advise the users to perform the task again rather than posting it back from SM13.

What is SNOTE? How to import the OSS notes?
SNOTE (SAP Notes Assistant) is available in SAP 4.6c after a plug-in and is by default from SAP 4.7EE.
Using SNOTE transaction code, you can directly install the Recommended Code changes in SAP system.
It creates a transport request which can be imported later on in the Quality and Production systems.
The advantage of SNOTE is that you need not get the notes added in the individual systems and can
have the change moved in to all the systems as per the guidelines.
There are two ways to import the OSS Note (SAP Notes).
1. Download the Correction to your system and import it.
2. Directly download from SNOTE transaction code (Only available from SAP 4.6c)

How to find if SAP is able to connect to Database?
o find out the status of connectivity, you can use the R3TRANS.EXE program. From the command
prompt, execute "R3Transd".
If you see a return code 000, it means that the database connection for the application is good.
R3trans will create an output file called trans.log which can help to diagnose if the return code is any
other value than 000.

Dialog work process Multiplexing
Generally large number of users log into SAP sytem. The dialog work processes (wp)
available to the users are limited due to performance & system limits. The objective of a
dialog work process is to handle the user requests quickly and display the results. Dialog
work process also takes large resources relatively to background processes for display
purposes. So it is not wise to have a dialog work process running for each user logged in. A
dialog work process is not assigned to a single user for longer time. When a dialog user fires
a request, the dispatcher assigns a dialog WP to handle the request. When the request is
processed, it relieves the work process from that user so that other users can use it. This
helps in handling requests from a large no of users with small no of dialog work process and
optimum use of resources.

Remote Function Call (RFC) in SAP
RFC is an SAP protocol to handle communications between systems which simplifies the
programming. A remote function call (RFC) is the call of a function module that
runs in a different system to the calling program. It is also possible to call afunction module in the same system as an RFC; normally RFCs are used
when the caller and the called function module run in different systems. Inthe SAP system, these functions are provided by the RFC interface system.
The RFC interface system enables function calls between two SAP systems,or between an SAP system and an external system. RFCs manage

3) Errors.
RFC describes an interface to call the function. In RFC communicationsbetween two SAP systems, the calling system uses an RFC definition in the
target system to access a specific function. The destination of an rfc call
might be R/2 connection, R/3 connection, internal connections, logicalconnections (like to logical systems) or TCP/IP (external systems)connections.
There are five types of RFCs in SAP
1) Synchronous RFC (sRFC)
It requires that the target system is active when the RFC is made.This type of rfc is used for communication between different
systems and between SAP Web AS and SAP GUI.
2) Asynchronous RFC (aRFC)
It doesnt require the target system to be active when RFC is made. Thisis used for parallel processing jobs and for communication between
different systems.
3) Transactional RFC (tRFC)
This is a variation of aRFC. The transactions are divided into stepsand are processes step by step. This is an asynchronous
transaction. This is helpful in scenarios where there is probability ofnetwork failure between the systems.
4) Queued RFC (qRFC)
This is a variation oftRFC. Here the individual steps are executedsequentially.
5) FastRFC
This is used for system internal communications. Interactions between
J2ee engine in sap & the abap runtime environment in the sameinstance are done using these RFC. This type of RFC is possible only
if both the source & target are on the same system.
The RFCs are managed using t-code sm59
Use t-code SMT1 to manage trusted systems

How to check if CUA is used
1) How do we know if Central User Administration (CUA) is used in a system?
You can quickly run transaction SU01 and see if the "Systems" tab is available. If it is then
CUA has been configured. Well there is another way to see whether CUA is used. Run
transaction code SCUA to see if there are any distribution models defined. Run transaction
code SCUL to see to view logs that are generated by CUA & if you have logged into a child
system, then goto transaction code SU01 and see, there will be no CREATE activity.
2) How to find derived roles under the master roles
1) Goto transaction SE16
2) Enter the table name : agr_define
3) Enter the master role in the second role field ( this field is in the second row) and
execute
4) Then you will see the derived roles based on the master roles

1. Login to the SAP service market place and download the SAP notes containing correction instructions to
the front-end.
2. Upload the notes from the frontend to the system using SAP notes assistant (Transaction SNOTE)
3. If you know the sap notes number you can download it by using assistant. Click on the button and
enter the SAP notes number.
4. Then the sap notes is implemented if its status is new ( click on button )
The uses of using note assistant are
1. It keeps a track of the processing status of all the SAP notes in the system
2. The notes can be de-implemented
3. It check consistency of SAP notes with the release of SAP system
4. It maintains the processing status of SAP notes
The notes assistant is an add-on. One has to import it from SAP service market place and install it in the system by using SAINT.
Note: When implemented SAP notes changes the ABAP code only. The ABAP dictionary objects are not changed. This has to be done
manually before implementing SAP notes so that the pre-requisites are met.

How to Determine the optimum No of Work Process
IF you want to find out the optimum no of work processes there are two ways
1) Goto transaction sm50 and click CPU as shown in figure
or press ctrl+shift+f6 . You will see the cpu total times of the work processes . If you have WPs whose CPU time is
very less (Say less than 0:20), you can decrease the number of WPS of that type . If the CPU time of certain type of
work process is high, you may decide to increase their no.
2) Another method is to go for transaction Al12 then click all servers as shown
Then you will see the total no of requests for each work process. If all the dialog work process have large no of requests then you can add
additional dia wps. If you have less dia wps with less requests , then you can decrease the no of dia wps.
This method is useful in deciding which operation mode to be used at a particular time.
