Hi,

There is no difference between developement class and package

4.6 c onwards developement class is known as package.

Thanks

hi,

Package

Related objects in the ABAP Workbench are grouped together in a package. The assignment of an object to a package is entered in the object directory (TADIR). The package determines the transport layer that defines the transport attributes of an object.

The packages are entered in the table TDEVC. They can be maintained in the following transactions:

Transaction SE80 -> Enter package -> Double-click the package

Transaction SM30 - Table/view name V_TDEVC

The packages are themselves objects of the ABAP Workbench. They belong to their own packages.

In contrast to its predecessor, the development class, a package has the following additional characteristics:

Packages can be nested.

Packages can contain their 'visible development objects' (visible outside of the package) in package interfaces.

Packages can have use access defined for other package interfaces.

Use

When an ABAP Workbench object is created, the system prompts you to assign it to a package. The package should describe the area that the object belongs to.

The representation of the object tree in the ABAP Workbench (transaction SE80) uses the package as a navigation aid. If there are more than 100 objects of a certain type (that is, ABAP programs), the object tree can no longer be clearly represented and it becomes increasingly difficult to use the ABAP Workbench. In this case, we recommend creating new packages with the same transport layer and distributing the objects to the new packages on the basis of the areas they belong to.

The following naming conventions for packages determine the packages' functions:

Package begins with A-S or U-X:

These packages are for SAP standard objects. Customer objects cannot be created in them. Changes to objects of these packages are recorded by the Transport Organizer (Request management) and can be transported (see field transport layer.

Package begins with Y or Z:

Customer objects can be created in these packages. Changes to objects in these packages are recorded by the Transport Organizer (Request management). The objects can be transported to other SAP Systems (see the field transport layer ).

Package begins with T (private test package):

When you create a package of this type, you can specify whether you want changes to be recorded. If so, objects that are edited are recorded in local requests by the Transport Organizer. This package does not belong to a transport layer. Objects can only be transported to other SAP Systems if a transport request is created.

Package begins with $ (local package):

Changes to objects are not recorded by the Transport Organizer. The package does not belong to a transport layer. The objects cannot be transported.

Package begins with a namespace prefix:

If you have reserved a namespace, then you can create packages (and other objects) whose names begin with the namespace prefix.

(Example of a namespace prefix /COMPANY/, example of a corresponding package /COMPANY/DEVCLASS)

Changes to these packages are recorded by the Transport Organizer, and can be transported.

Hi,

Development class classifies the objects belonging to the same development project.

When a user creates a object in R/3 system, the object needs to be stored in particular development class. The development class are object themselves. In R/3 system you store objects.

In local object i.e., object is stored in $tmp class and cannot be transported from one system to another.

User can assign his own development class and can be transported.

Package is for the group of objects in the same module or similar purpose. development class and package is having same meaning.
