SAP Admin Tricks & Tips.

1. Problems with username/passwords while setting JCO's?... try with the password in UPPERCASE.

2. Going home in a hurry?, use transaction /nex to close all your sessions at the same time in specific application server you are logged-in.

3. In an R/3 screen, use %pc to download any TCode full page in any format you want.(.htm, .txt etc). Also use TCode /nSO21 to specify the default download location (this is very useful as saving all files to the sapworkdir can be little annoying at times)

4. Show Work Process usage over time by running SM50 -> List -> CPU. This shows CPU usage in minutes since startup. If all of your DIA WP's show time, then consider adding more.

5. If you want to select text on your SAP screen and if you are not able to do it. use Ctrl+Y and then you can select text.

6. To access history of Tcodes used, click on the Tcode command field and use UP and DOWN arrow keys.

7. To display the checked object when not authorized call transaction SU53. It reports the last objects verified and also the respective values. Incase missing authorization through pop-up then close it (click cross mark) instead of continue it. Then run SU53 immediately either in same session (/nSU53) or in new session (/oSU53).

8. Use ctrl+? to go to the tcode command field on SAP screen.

9. Enter /i on tcode field to delete the current session.

10. Enter /nend to cancel all SAP sessions and log off.

11. Use ALT+F+W and ALT+F+U in SAP Easy Access Screen to download and upload the user favorites within/across systems.

12. To send a SAP message to another person use Function Module TH_POPUP from transaction SE37.

13. Ctrl & + to open new SAP session

14. ctrl+shift+F8 System Administration information.

15. Open SAP Notes on Windows via Batch File

Here is a quick tip on how to open a SAP Note by just typing in or pasting the SAP Note number. Its very convenient, when you are reading a PDF document (possibly a installation/configuration guide) and you come across interesting SAP Notes that you want to quickly check.
Create a batch file using your notepad with the following text:
@ ECHO QUICK COMMAND TO DISPLAY SAP NOTE
@ ECHO ----------------------------------------
@ SET /P sapnote=Please provide SAP Note number ?
@ START /MAX iexplore -new https://service.sap.com/sap/support/notes/%sapnote%?nlang=E
@ PAUSE
Next Create a shortcut to the batch file and put it on your desktop.
Next time you wish to open a SAP Note, simply click on the shortcut and you should get a prompt like the following:
QUICK COMMAND TO DISPLAY SAP NOTE----------------------------------------Please provide SAP Note number ?
Here provide the note number and press the enter key.
The command will fire up a new internet explorer window and open the SAP Note in it. It will help if you have SSO setup for your OSS Userid as you wouldn't need to enter your userid and password.
Hope that helps.
