Packagae or the dev class means the group of related objects in SAp

for example all th objects related Sales module are grouped together under a package called ZSD, when you assign a package a request is created which is used to tranport the object to other systems.

You can create any number of fields in a table.

Package is a place where we can group our objects.For eg we can create our own package ZMM -to store MM related objects.ZSD -to store SD Related objects...

Development class is called as Package from release 4.7e onwards.

Thanks and Regards,

hey sunil

Packages emulates the functionality of development classes in earlier R3 releases.

Developments are assigned to packages that represent similar business processes.

Actually there is a difference - packages have more features than development classes. The help explains it a bit more:

*****

Packages extend the concept of development classes to improve modularization, encapsulation, and decoupling in the SAP System.

Development classes, used until now, are simple containers for development objects, provided with a transport layer that specifies how they were to be transported. As an enhancement to development classes, packages include the following attributes: nesting, interfaces, visibility, and use accesses.

Nesting is the ability of a package to include other packages within the package hierarchy.

Visibility is an attribute of package elements. A development element can be visible from outside the package. (It is always visible inside its own package, though not necessarily all the packages embedded in this package). A development element is visible externally if it is included in at least one package interface.

The use access gives a package the right to use the development elements in the package interface of another package. Note that this right is one-way only.
