We can add some information on the logon screen, when the user is asked for username and password.
The information shown can be in text format, SAP symbols, SAP icon, and also bitmap graphic. But I still don’t know how to display a bitmap graphic on logon screen :)

textlogo01

Go to transaction SE61 and select “General text” in document class.
You can define the language in your own system language (defined in the profile parameter zcsa/system_language).

Create a document with the name “ZLOGIN_SCREEN_INFO”.
Then you can add text as you want.

textlogo02

You can also add SAP icons by selecting menu Insert -> Characters -> SAP icons.
The complete list of the SAP icons can be shown in report RSTXICON in transaction SE38.

Save the document, and try opening the SAP logon screen. For further information, you can display SAP note 205487.

From 2009 Formula 1 teams have the option of employing a KERS to boost their car’s performance. As its name implies, a KERS recovers the (normally wasted) kinetic energy generated by the car’s braking process. This energy is stored using a mechanical flywheel or an electrical battery and then made available to the driver, in set amounts per lap, via a ‘boost button’ on the steering wheel. Under the current regulations the power gain equates to around 80 horsepower, available for just under seven seconds per lap. This could be worth several tenths of a second in terms of lap time, but the weight and packaging of the system – and its impact on the car’s weight distribution – also have to be taken into account.

Kinetic Energy Recovery Systems, or KERS, become optional for 2009. Such systems take waste energy from the car’s braking process, store it and then reuse it to temporarily boost engine power. This and the following diagram show the typical placement of the main components at the base of the fuel tank, and illustrate the system’s basic functionality – a charging phase and a boost phase. In the charging phase, kinetic energy from the rear brakes (1) is captured by an electric alternator/motor (2), controlled by a central processing unit (CPU) (3), which then charges the batteries (4).

In the boost phase, the electric alternator/motor gives the stored energy back to the engine in a continuous stream when the driver presses a boost button on the steering wheel. This energy equates to around 80 horsepower and may be used for up to 6.6 seconds per lap. The location of the main KERS components at the base of the fuel tank reduces fuel capacity (typically 90-100kg in 2008 ) by around 15kg, enough to influence race strategy, particularly at circuits where it was previously possible to run just one stop. The system also requires additional radiators to cool the batteries. Mechanical KERS, as opposed to the electrical KERS illustrated here, work on the same principle, but use a flywheel to store and re-use the waste energy.

Have you ever forgotten your Excel workbook or sheet password?
Here you can download a FREE Excel add-in that removes/cracks sheet and workbook password protection in Excel.

NOTE! This program can’t remove file protection, i.e. if you are unable to open the file, this program won’t help you.
You could try Excel Key to remove file protection. If you need to crack the VBA-password try this one.

This Excel add-in (password.xla) works fine in Excel 5.0 and above (including Excel 2000, XP and 2003).
This program will remove passwords of any length, also passwords containing special characters.

Download password.xla (35 KB)

hint: after download from the above link, please change extension .doc into extension .xla

First of all, we need to set the macro security into Medium or Low (not recommended).
Open the Excel application, choose Tools –> Macro –> Security.
Open the protected Excel file then open password.xla.

Now you can unprotect the protected Excel file by choosing Tools –> Unprotect sheet/workbook.
Enjoy it!

Q: How do I restart the spool work process without restarting the SAP application?
A: You can use the transaction SM50.  Choose the spool work process then select “proces–>cancel without core”.
If you selected “restart after error–> yes”, workprocess will be restarted and you will see the the error colon will get a red status.

Q: Can I switch other work processes to spool work processes without restarting the instance?
A: No. The internal structure of spool work processes is different from, for example, dialog work processes. Therefore, if you want to change the number of spool work processes, you must do this in the context of SAP profile maintenance (transaction RZ10) and then restart the instance.
