hi friend,

i am new in ABAP 6.0 , but work with ABAP4.0 .

My problem is when i copy Prog "RM08NAST" but in this i find new Sta. is ENHANCEMENT-POINT , so what is this .

thanks in Advance

ENHANCEMENT-POINT

Defines a position in an ABAP program as an enhancement option, at which one or more source code plug-ins can be inserted.

Syntax

ENHANCEMENT-POINT enh_id SPOTS spot1 spot2 ...

[STATIC]

[INCLUDE BOUND].

Extras:

1. ... STATIC

2. ... INCLUDE BOUND

Effect

: This statement defines an explicit enhancement option at the current position in the program at which a source code enhancement can be made. In program generation, the source code plug-ins of the assigned enhancement implementation that are available in the current system and have a switch in the status stand-by or on, are inserted at this position.

If the addition STATIC is not specified, the source code enhancement is dynamic. This means that in program execution, only those source code plug-ins are executed whose switch has the status on. If a source code plug-in does not have a switch assigned to it, it is handled in the same way as a plug-in with a switch in the status on.

With enh_id, an ID must be specified directly for the enhancement option, which is unique in the current compilation unit without the addition INCLUDE BOUND, and with this addition, is unique in current Include program. At least one enhancement spot must be assigned to the enhancement option using the specification simple enhancement spots spot1, spot2, and so on.

Within enhancements, one or more source code plug-ins can be created for one enhancement option. A source code plug-in is created by the assignment of an enhancement implementation in the Enhancement Builder. This automatically generates an empty source code plug-in with a unique ID, which is displayed underneath ENHANCEMENT-POINT in the Editor, where the actual enhancement can be implemented between ENHANCEMENT and ENDENHANCEMENT.

A source code plug-in is assigned to only one enhancement option. Multiple source code plug-ins of one enhancement implementation and the source code plug-ins of multiple enhancement implementations can be assigned to one enhancement point.

Notes

: In the terminology of the enhancement concept, the statement ENHANCEMENT-POINT includes both the enhancement spot element definition and the enhancement spot invocation of the enhancement option.

The statement ENHANCEMENT-POINT can either be entered directly or created by choosing Edit ? Enhancement operations ? Create enhancement in the Enhancement Builder. After the program has been saved or created using Edit ? Enhancement operations ? Create enhancement, the statement can only be deleted by choosing Edit ? Enhancement operations ? Delete enhancement.

In addition to the enhancement options explicitly specified by ENHANCEMENT-POINT, ABAP programs also contain implicit enhancement points, which can also be enhanced using source code plug-ins.

Addition 1

... STATIC

Effect

: The addition STATIC is used to define a static source code enhancement. In a static source code enhancement, all incorporated source code plug-ins are taken into account when the program is executed, including those whose switch is in the status stand-by.

Note

: The STATIC addition is intended for the enhancement of data declarations, while the statement ENHANCEMENT-POINT without the STATIC addition is designed for the enhancement of executable coding. When the statement is executed using Enhancements ? Create enhancement, the addition is set according to this selection.

Addition 2

... INCLUDE BOUND

Effect

: This addition can be entered in Include programs. It links the source code enhancement to the current Include program. Each program that incorporates an Include program only includes the source code enhancements that are defined with this addition. Source code enhancements created using the INCLUDE BOUND addition have their own namespace in each Include program. This ensures that if several Include programs are integrated into one compilation unit, no namespace conflicts arise, either between Include programs, or with the source code enhancements of the compilation unit.

Without the addition INCLUDE BOUND, a source code enhancement is assigned to only one compilation unit. If the statement ENHANCEMENT-POINT is executed in an Include program without this addition, a compilation unit must be assigned to it in the Enhancement Builder.

Note

: In an Include program, Include-bound and non-Include-bound source code enhancements can not be defined at the same time. This also applies if an Include program incorporates other Include programs.

The basic idea of the Enhancement Framework is to make modification-free enhancements of development objects such as programs, function modules, global classes, and Web Dynpro components.

All these technologies and the new kernel-based BAdI are now integrated in one Framework that has the following features:

Enhancements of existing development objects on different levels - for example, in an industry solution, in the IT department of the customer, and finally in a customer's company.

Better upgrade support

Switching of enhancements with the Switch Framework (not possible externally with 7.0)

Support for grouping enhancements and appropriate tool support for the documentation.

Explicit and Implicit Enhancement Options

Principally, there are two types of enhancement options:

The developer of the corresponding development object must insert the options of the one kind into the coding so that enhancements can be done there at a later time. These preconceived enhancement possibilities are called explicit enhancement options.

You can perform enhancements on implicit enhancement options without the developer of the appropriate compilation unit having to do anything. Enhancement options are always available in programs, global classes, function modules, and includes.

In other words, the implicit enhancement options are for free, provided by the framework, while the explicit ones need to be inserted explicitly, as the name indicates.

Explicit Enhancement Technologies

There are two types of explicit enhancement options:

Enhancement points allow you to insert source code plug-ins. These are additional code lines that, if they exist, are executed there additionally. Explicit enhancement options of the type Enhancement Section behave in the same way - the only difference being that the source code plug-in replaces the section in the original code.

Business Add-Ins (BAdIs) are "hangers" for object plug-ins. A BAdI definition comprises an interface with methods. BAdIs are enhanced by classes that implement the BAdI interface. If you instantiate a BAdI and then call its methods, you can, among other things, specify which method implementations are to be carried out on the basis of filter values. In other words, a BAdI method call is a dynamic method call with a specified interface, for which it is not determined until runtime which method implementations are to take place.

Implicit Enhancement Technologies

Implicit enhancement options are fixed points in compilation units - that is, points that remain intact even if the code is changed:

You can always insert source code plug-ins before the first and the after the last line of includes, methods, reports, and function modules.

You can always add further optional parameters to function modules.

For global classes, there are different permanent, implicit options for enhancements: You can insert additional attributes or methods, and you can add optional parameters to existing methods.

See the doc

ENHANCEMENT

Syntax

ENHANCEMENT id.

...

ENDENHANCEMENT.

Effect

: These statements define a source code plug-in with the ID id. Between the statements, a source code enhancement can be implemented. The control structures and processing blocks contained in the implementation must be complete.

The statements ENHANCEMENT and ENDENHANCEMENT can not be entered and edited directly. Instead, they are generated by the ABAP Workbench when enhancements are created as a part of the enhancement concept. The ID id is also assigned by the Workbench.

Notes

: In the terminology of the enhancement concept, a source code plug-in is an enhancement implementation element of a (simple) enhancement implementation.

Although source code plug-ins are displayed in the same source code as the corresponding enhancement options ENHANCEMENT-POINT or ENHANCEMENT-SECTION, they are actually stored in other Include programs that are administrated by the Enhancement Builder.

It is not yet possible to enhance a source code plug-in using further source code plug-ins. This means it is not currently possible to use the statements ENHANCEMENT-POINT and ENHANCEMENT-SECTION between ENHANCEMENT and ENDENHANCEMENT.

Hi,

ENHANCEMENT-POINT can either be static (for example, additional data declaration) or dynamic (for example, additional coding).

Refer the very useful links below:

Enhancement-Point is a part of the new enhancement framework. He is some lite reading.
