Send System Message to User
There is one builtin function TH_POPUP that we can used to send message to the user.
Go to call function transaction SE37 and execute this function
Overlaying Character Fields
Is good to use if you want to fill the number for certain format.
e.g if the data contain value 65 and the format data should be 65000
The OVERLAY statement overlays one string with another:
OVERLAY c1 WITH c2 [ONLY str].
This statement overlays all positions in field c1containing letters which occur in str with the contents of c2. c2remains unchanged. If you omit ONLY str , all positions of c1 containing spaces are overwritten.
If at least one character in c1 was replaced, sy-subrc is set to 0. In all other cases, sy-subrc is set to 4. If c1 is longer than c2, it is overlaid only in the length of c2.
Example
DATA: t(10) TYPE c VALUE 'a c e g i ',
string LIKE t,
over(10) TYPE c VALUE
'ABCDEFGHIJ',
str(2) TYPE c VALUE 'ai'.
string = t.
WRITE string.
WRITE / over.
OVERLAY string WITH over.
WRITE / string.
string = t.
OVERLAY string WITH over ONLY str.
WRITE / string.
Output:
a c e g i
ABCDEFGHIJ
aBcDeFgHiJ
A c e g I

1) change the sap gui logon setting
2) Reinstall MADC
Solution for number two is working for me and my system using windows XP sp3.
Below is the guide taken from this site
I had a customer that just couldn’t get MDAC to work under XP. Reinstalling XP SP3 didn’t work. Microsoft doesn’t make anything available to reinstall MDAC individually. So it’s a complete nightmare to fix it. Luckily, I was able to solve the issue with these steps:1. Click Start > Run and type %windir%\inf and click OK.
2. Right-click mdac.inf and select Install.
This is where the nightmare started for me. I didn’t have any of the files below. I had to copy the OLE DB, msadc, Ole DB and Binaries folders from another computer and place them in the C:\Program Files\Common Files\System\ folder. If you are missing the servicepackfiles folder, you will have it after you reinstall XP Service Pack 3. You can also just extract the files from the SP3 file by using the windowsxp-kb936929-sp3-x86-enu.exe –x command.
3. When prompted for each of the following files, try to browse and locate them in the directories specified.
- adcjavas.inc – C:\Windows\servicepackfiles\i386
- handler.reg – C:\Program Files\Common Files\System\msadc
- MDACRdMe.htm – C:\Program Files\Common Files\System\Ado. I had to rename MDACReadme.htm to MDACRdMe.htm first.
- oledbjvs.inc – C:\Program Files\Common Files\System\Ole DB
- mssoap1.dll – C:\Program Files\Common Files\MSSoap\Binaries
- mssoapr.dll – C:\Program Files\Common Files\MSSoap\Binaries
After all these steps, MDAC was working again.

Introduction Object Oriented Programming in SAP ABAP
Object oriented programming tries to map the real world objects with their attributes and methods as realistically as possible in program constructs. The aim is to create the program flow in such a way as if it is taking place in the real world. This makes the interaction between the developer and the user easier. The user can formulate business requirements on a program in the language in which the user is familiar with and the developer can convert these directly instead of the classic programming model.
In the object oriented programming model a different approach is used. Attributes and methods which belong to a specific object are grouped together and made accessible to the user using a well defined interface behind which the actual implementation details are hidden. so, the attributes of the object are only changed by the methods of the object and not directly by the user of and object. This ensures that the status of the object is always consistent.
When do you call an object an object oriented programming? if it has these features.
Abstraction
Abstraction refers to the ability to reflect the real world processes as realistically as possible through programming. These processes can be a business or a technical nature.
Encapsulation
Implementation details are hidden behind well-defined an documented interfaces. They ensure that the abstract representation of a object is used only in accordance with its spefication.
Inheritance
New abstractions i.e. classes are derived from existing ones. They inherit all the attributes and methods of the higher class and can expand and specialize them.
Polymorphism
Different objects can present the same interface to the outside. A user only needs to know the interface and need not know every minute details of the classes.
