Speeding Up Windows

1. Disable Indexing Services
Indexing Services is a program that perform index to your computer. When you do a search for something on your computer, it will search faster by scanning the index lists but this system service is completely unnecessary. To disable do the following:

• Go to My Computer
• Right click on C: drive
• Click Properties
• Uncheck “Allow Indexing Service to index this disk for fast file searching”
• Apply to all files and folders
• If Windows prompt that file is in use, click ignore to all

2. Optimise Display Settings
Windows XP original theme visual items can waste system resources. To optimise:

• Go to Start
• Click Settings ( if you can’t find it, go to the next step)
• Click Control Panel
• Click System
• Click Advanced tab
• In the Performance tab click Settings
• Then select Adjust for best performance
• Click Apply and Ok
• Windows will take 1-3 minutes to implement the new changes.

3. Speedup Folder Browsing
You may have noticed that everytime you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing significantly:

• Open My Computer
• Click on Tools menu
• Click on Folder Options
• Click on the View tab.
• Uncheck the Automatically search for network folders and printers check box
• Click Apply
• Click Ok
• Reboot your computer
  

4. Optimise Your Pagefile
If you give your pagefile a fixed size it saves the operating system from needing to resize the page file.

• Right click on My Computer and select Properties
• Select the Advanced tab
• Under Performance choose the Settings button
• Select the Advanced tab again and under Virtual Memory select Change
  

• Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.



• Click ok and restart computer

5. Disable Prefetch on Low Memory Systems
Prefetch is designed to speed up program launching by preloading programs into memory - not a good idea is memory is in short supply, as it can make programs hang. To disable prefetch:

• Click ‘Start’ then ‘Run’
• Type in ‘Regedit’ then click ‘Ok’
• Navigate to 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters\’
• Right-click on “EnablePrefetcher” and set the value to ‘0′
• Reboot.

6. Improve XP Shutdown Speed
This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown.

• Go to Start then select Run
• Type ‘Regedit’ and click ok
• Find ‘HKEY_CURRENT_USER\Control Panel\Desktop\’Select ‘WaitToKillAppTimeout’
  Right click and select ‘Modify’
• Change the value to ‘1000′
• Click ‘OK’
• Now select ‘HungAppTimeout’
• Right click and select ‘Modify’
• Change the value to ‘1000′
• Click ‘OK’
• Now find ‘HKEY_USERS\.DEFAULT\Control Panel\Desktop’
• Select ‘WaitToKillAppTimeout’
• Right click and select ‘Modify’
• Change the value to ‘1000′
• Click ‘OK’
• Now find ‘HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\’
• Select ‘WaitToKillServiceTimeout’
• Right click and select ‘Modify’
• Change the value to ‘1000′
• Click ‘OK’

7. Make Your Menus Load Faster
This is one of my favourite tweaks as it makes a huge difference to how fast your machine will ‘feel’. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.

• Go to Start then Run
• Type ‘Regedit’ then click ‘Ok’
• Find “HKEY_CURRENT_USER\Control Panel\Desktop\”
• Select “MenuShowDelay”
• Right click and select “Modify’
• Reduce the number to around “100″

8. Speedup Folder Access - Disable Last Access Update
If you have a lot of folders and subdirectories on your computer, when you access a directory XP wastes a lot of time updating the time stamp showing the last access time for that directory and for ALL sub directories. To stop XP doing this you need to edit the registry. If you are uncomfortable doing this then please do not attempt.

• Go to Start and then Run and type “regedit”
• Click through the file system until you get to
• HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem”
• Right-click in a blank area of the window on the right and select ‘DWORD Value’
• Create a new DWORD Value called ‘NtfsDisableLastAccessUpdate’
• Then Right click on the new value and select ‘Modify’
• Change the Value Data to ‘1′
• Click ‘OK’

SAP R/3 Tips and Tricks - by Ricardo Fernandes de Miranda

Lately I found a very helpful SAP website.
Resources from: http://www.sapfans.com/sapfans/saptips.htm

• 
  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.

• 
  Special
  copy 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

SAP
R/3 Hints
TOP

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 teams
  and 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

SAP
R/3 Enhancements
TOP

---

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.

SAP
R/3 Troubleshooting
TOP

---

• 
  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.

SAP
R/3 Security
TOP

---

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.

Note:	I do not have to waste my time telling you to change all default passwords.
	Make sure to have the master user SAP* in all clients otherwise anyone can log into your system. See Tips & Tricks.
