JavaScript effect that will let you edit any webpage

2007-02-05T06:45:00.000-08:00

This is a pseudo-hack.. you're not really changing anything on their server, but it lets you play around with websites layout and objects that are usually locked. You can edit text, move pictures, etc.
Only works in Internet Explorer as far as I can tell, since Firefox disables javascript by default for security reasons.

1) Go to any website

2) Delete everything in the address bar

3) Paste the following code in the address bar:

Code:

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

4) Start playing

International Link Outage - Official TMNET Statement
by Vijandren Ramadass
Wednesday, 27 December 2006 02:12 PM

ImageWe wish to inform our customers that the Internet service is currently experiencing a degradation in performance caused by several outages at some of the international links.

This is attributed to the Richter 7.1 magnitude earthquake that struck off the southern coast of Taiwan at 12.07 a.m. on 27th December 2006, which caused the APCN2 (Asia Pacific Cable Network 2) submarine cable fault between Shantou, China and Tanshui, Taiwan and between Lantau, Hong Kong and Chongming, China.

This has caused outages at several TM Net international transit and peering links, mainly to the said countries. As a result, Internet users in Malaysia and other parts of Asia may be experiencing some delay when assessing content and websites hosted outside of Malaysia, especially in U.S., Japan, China, Taiwan, Korea and Europe. TM Net has taken immediate action to divert traffic through other back-up links to reduce the traffic congestion.

The international providers are carrying out immediate restoration works to rectify the problem. We will be making further announcements when the service has resumed.

TM Net Sdn Bhd apologizes for any inconvenience caused whilst at the same time, we would like to assure you that we are doing all that is necessary in order to restore the service as soon as possible.

Customers can call TM Net Customer Interaction Centre at 1-300-88-9515 (24 hours) or 1-300-88-1515 from 8:00 a.m. till midnight or e-mail us at custcare@tm.net.my for further enquiries about this matter.

How to troubleshoot authorization issue

2006-12-21T19:01:00.000-08:00

1. When user receive an authorization error such as the below dialog box, request the user to enter /nSU56 or /nSU53 to display more details on the authrization issue.

2. In Su56, expend the menu and you will see the object value and transaction type. In this scenario we know user do not have authorization on object value "0111" and transaction "V"

3. We now know that user is not authorized for object "C_PROJ_TCD", value "0111" and type "V".

4. Use T-Code S_BCE_68001425 to search for the authorization object. In this scenario we enter the username and authorization object and it will display the role.

5. Below is the results. Now we have to find the correct role which we need to give authorization too. If you are not sure, consult with your consultant.

6. Open /nPFCG to edit the role.

7. Enter the role name.

8. Click on Authorization tab and click "display authorization data"

9. Expend the menu and locate the object or use the "FIND" button to search for object "C_PROJ_TCD"

10. Below are the authorization you need to provide accordingly.

11. In this case, we select "0111 which is Basic WBS dates"

12. Save

13. Click on generate profile button

14. Now do user comparison

15. Ask user to re-login and try the transaction again.

Addtional Info
If you know the Authorization object and would like to search which transaction is using it, you can open this transaction from SAP menu.

Speeding Up Windows

2006-11-23T02:25:00.000-08:00

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

2006-11-21T02:41:00.000-08:00

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
command field formats

/n	Skip to the next record if you are processing one batch input session
/bend	Cancel a batch input foreground process
/nend	Close all R/3 sessions and logoff
/nxxxx	Call the transaction xxxx in the same session
/o	Generate a session list
/oxxxx	Call the transaction xxxx in an additional session
/i	Delete the current session
/h	Turn the debug mode on
/$tab	Reset all buffers (for System Administrators)
/$sync	Synchronize instances buffers (for System Administrators)

Report command field formats

%pri	Print the current report
%pc	Download the current report
%sc	Call the find function
p+	Go to the next page
p-	Go to the previous page
p++	Go to the last page
p--	Go to the first page

Helpful reports

Unconditional mode when importing
or exporting a request/transport

Run the command R3trans
-u under user «SysID»adm.

Main return codes of tp
program

0	Successfully done
4	Warnings occurred
8	Errors occurred

RSPO0041	Removing old spooling objects
RSSNAPDL	Clean the old ABAP error dumps

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.

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.

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.

After
3 wrong password the connection is automaticly closed.

After
5 wrong password the user is locked.

Password
length at least 6 characters.

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.
