- Logging on without being authorized
Client 066 usually exists in a SAP system due to EarlyWatch services. Often this
client does not have master users. If it is true, anyone can log into the
system using the client 066, user SAP*, and password PASS. Enjoy yourself.
- Specialcopy and paste
Click on the area and press CTRL+Y. It allows you to copy many lines at once
and paste them afterwards.
- Long messages on footer
Click on the message and hold the mouse button. After moving the mouse to the
left side.
- Direct input logs
The transaction BMV0 (direct input logs) shows all direct input logs.
- Graphics on SAPscript
The program RSTXLDMC can be used to upload graphics (file extension .tif on
PC files) into individual standard text.
- Adding icons
Check the icon code using transaction ICON. A technical view can be found at
the include named «ICON». Sequences of characters begin and
finish with the symbol @. Even plain files under operating system can contain
those strings.
- Filling up an empty date field quickly
Strike the key F4 (or click on matchcode symbol) and press ESCAPE. The current
date is automaticly set.
- Setting up module FI/CO without using IMG
Almost all parameters can be set using the transactions ORFA (Asset Accounting),
ORFB (Financial Accounting), and ORKS (Cost Center Accounting).
- Displaying check object when not authorized
Soon after the lock try to access the transaction SU53. It reports the last
objects verified and also the respective values.
- Table analyses between two systems
The contents of a table between two systems can be checked through the transaction
OY19.
- Correction and transport system
The transaction SE10 provides the easiest way to manage any request/transport
and corrections.
- General command field formats
| /n | Skip to the next record if you are processing one batch input session
|
- Report command field formats
| %pri | Print the current report
|
- Helpful reports
| RSCLTCOP | Copy tables across clients
|
- Unconditional mode when importing or exporting a request/transport
Run the command R3trans
-u under user «SysID»adm.
- Main return codes of tp program
- Scheduling of system maintenance jobs
| RSBTCDEL | Clean the old background
job records |
- Locking the whole system
Using the command tp locksys «SysID» only the user SAP* will be allowed to login.
The command tp unlocksys «SysID» cancels the lock.
- Connection between SAP R/3 and operating system
The command sapevt can be used to trigger an event from the operation system. Thus, a job
previously defined within R/3 will be released.
- SQL code help
Run the command oerr ora «error number» under user ora«SysID».
- Oracle import and export explanations
Run the command imp help=yes under user ora«SysID». This format can also be used with exp,
impst, and expst.
Of course it does not guarantee a successful implementation. It is a great
deal of summed up aid, though.
- Team integration has to be enhanced
- Set high standards of performance for implementation team
- IT teamsand users have to work closely during the implementation
- New ways of thinking and acting must not be discarded
- Do not underestimate the user training needs
- Project management should be on the critical list
- The nearest SAP branch should be your partner
- Consultants are not always the key to succeed
- Consultants are a good source of knowledge. On the other hand, letting them make configuration
changes the transfer of knowledge will be harmed
- Foreign consultants usually do not know country-specific details
- Deepening your basis knowledge is always useful
- Avoid changing standard R/3 objects as much as possible
- Always follow the SAP rules to give names to your own objects
- Establish SAP connection as soon as possible
- Exchange information with other companies
- Focus on interfaces with non-R/3 applications
- Plan the whole environment carefully (servers, network, protocols, etc.)
- Development and production environment should be totally independent
Some special features allow you wide modifications without changing standard
SAP R/3 objects. Those
techniques are not as widespread as they should be. In fact they are powerful
tools.
- Field exit
After entering a value in a field, it can be checked through a field exit. The
system makes the field value available to be checked and changed in an
ABAP/4 function.
- User exit
Points previously set in the system that let you evaluate data. The fields available
are also previously defined by SAP. All fields value available can be checked
in an ABAP/4 program.
- Validation
It allows solid data entry regarding special rules. According to previous
rules, the system can evaluate an entry and a message can appear on the
user’s terminal if a check statement is not met. A validation step contains
prerequisite statement and check statement. Both of them are defined using
Boolean Logic or calling an ABAP/4 form.
- Substitution
Fields contents can be changed using substitution. When data are being entered,
the data can be substituted by another value regarding rules previously
defined. A substitution step contains prerequisite statement, substitution
value and substitution exit. All of them are defined using Boolean Logic
or calling an ABAP/4 form.
- Set
Values or ranges of values are specified under a set name. Sets are easier to
create and maintain instead of using tables. They give you more flexibility
when maintaining your system.
- Key words
It allows changes on field description according to data element. The short
key word used on most screen to identify the corresponding field contents
can be changed too.
- Requirements & formulas
ABAP/4 forms that can be used to handle pricing procedures, rounding rules, copy
and data transport Sales activities.
- System gets stuck
It happens mostly when archive area is overloaded. Run the program brarchive
with deletion option to release disk space.
- Short dump
Not always the problem is technical. Try to create all SAPoffice users through
transaction SO32 (create all SAPoffice users) and review your application
data carefully.
- Field exits are completely ignored
Make sure your SAP profile parameter contains the option abap/fieldexit = yes.
- Transaction SE16 (table contents) does not work properly
Make usage of the menu option to regenerate the display program. You can also
try changing key words according to field names. Choose Option -> Parameters
users.
- Rollback segments are too small
Before increasing up the rollback segment size you should verify your programs.
Very often the problem belongs to them.
- Files for rollback segments are already enormous
Check the rollback segments configuration. It has to match the allocated area
on tablespaces. Changes have to be done using Oracle tools.
- Extended help under windows does not link correctly
Check the file sapdoccd.ini under your presentation server. It must be
present in the main windows directory and should assign to help files directory.
- Release procedure with classification does not work
As a matter of fact you are not the only one to notice it. It hardly works.
Before using release strategy you should apply all notes on OSS. Pray might
be useful too.
- Transport area is overloaded
The command tp clearold «SysID» cleans up the transport
area according to parameters previously set on the plain file TPPARAM.
- Instance does not establish communication
Shutdown the whole system and check the Interprocess Communication Facilities. Any
references should be found. Either the command IPCS (UNIX) or showipc
«INSTANCE NUMBER» (SAP) show all message queue, semaphore
set and shared memory identifier. Before trying again you have to remove
them using the command IPCRM (UNIX) or cleanipc «INSTANCE
NUMBER» (SAP).
| Note: | Research based on version
3.0f under Unix, Oracle data base and Windows. |
Simple changes can rise your system security. Usage of SAProuter is a good choice
when correctly implemented. Login through SAP LogonPad (from version 3.0f
onwards) improve the access control. SAP profile parameters shall also
contain:
- Rdisp/gui_auto_logout = 1800
The user connection is closed after 30 minutes without usage.
- Login/fails_to_session_end = 3
After 3 wrong password the connection is automaticly closed.
- Login/fails_to_users_lock = 5
After 5 wrong password the user is locked.
- Login/min_password_lng = 6
Password length at least 6 characters.
- Login/password_expiration_time = 90
Password expires after 3 months.
Indeed these powerful ABAP/4 functions are very interesting and can bring some
advantages. Improve your home development easily. They belong to standard
objects and should never be changed.
