Abstract

A method and system for employing client interfaces for packages. In one embodiment, an access object associated with a service provided by a first package is located, where the service is seeking to access content residing at a second package. A client interface is then created at the second package using the access object. The client interface is used to provide access to the content by exposing the content to the service via the client interface.

Claims

1. A method comprising:

locating an access object assigned to a service of a service package at a service computer system, wherein

the service computer system is coupled to a client computer system, the client computer system to include a client package further including a content and a dependency log of objects to log static and dynamic uses of objects,

the service package includes a service package interface to publish objects and services of the service package,

the access object is included in the service package and published via the service package interface, and

the access object identifies the content of the client package;

creating, based on the published access object, a client interface included in the client package, the content of the client package accessible to the service of the service package via the client interface, wherein access to the client interface is controlled by a dependency control list included in the client package; and

accessing the content by exposing the content to the service using the client interface.

2. The method of claim 1, further comprising determining whether the client package includes subpackages, each subpackage having additional content, wherein the service to access the additional content of the subpackages at the client package using the client interface, access to the client interface by the subpackages is controlled by the dependency control list included in the client package, and objects used by the subpackages are logged in the dependency log included in the client package.

3. The method of claim 2, wherein each of the subpackages to inherit the dependency control list of the client package.

4. The method of claim 1, wherein the content comprises a plurality of objects including one or more of global variables, local classes, structure types, function modules, dynpros, and types from other packages.

5. A system comprising:

means for locating an access object assigned to a service of a service package at a service computer system, wherein

the service computer system is coupled to a client computer system, the client computer system to include a client package further including a content and a dependency log of objects to lair static and dynamic uses of objects,

the service package includes a service package interface to publish objects and services of the service package,

the access object is included in the service package and published via the service package interface, and

the access object identifies the content of the client package;

means for creating, based on the published access object, a client interface included in the client package, the content of the client package accessible to the service of the service package via the client interface, wherein access to the client interface is controlled by a dependency control list included in the client package; and

means for accessing the content by exposing the content to the service using the client interface.

6. The system of claim 5, wherein the client package further includes subpackages, wherein each subpackage having subpackage content relating to the content, wherein the service to access the content of the subpackages at the client package using the client interface, access to the client interface by the subpackages is controlled by the dependency control list included in the client package, and objects used by the subpackages are logged in the dependency log included in the client package.

7. The system of claim 6, wherein each of the subpackages to inherit the dependency control list of the client package.

8. The system of claim 5, wherein the content comprises a plurality of objects including one or more of:

global variables, local classes, structure types, function modules, dynpros, and types from other packages.

9. A machine-readable storage medium comprising instructions which, when executed by a machine, cause the machine to:

locate an access object assigned to a service of a service package at a service computer system, wherein

the service computer system is coupled to a client computer system, the client computer system to include a client package further including a content and a dependency log of objects to log static and dynamic uses of objects,

the service package includes a service package interface to publish objects and services of the service package,

the access object is included in the service package and published via the service package interface, and

the access object identifies the content of the client package;

create, based on the published access object, a client interface included in the client package, the content of the client package accessible to the service of the service package via the client interface, wherein access to the client interface is controlled by a dependency control list included in the client package; and

access the content by exposing the content to the service using the client interface.

10. The machine-readable storage medium of claim 9, wherein the instructions which, when executed, cause the machine to determine whether the client package includes subpackages having additional content, wherein the service to access the additional content of the subpackages at the client package using the client interface, access to the client interface by the subpackages is controlled by the dependency control list included in the client package, and objects used by the subpackages are logged in the dependency log included in the client package.

11. The machine-readable storage medium of claim 10, wherein each of the subpackages to inherit the dependency control list of the client package.

12. The machine-readable storage medium of claim 9, wherein the content comprises a plurality of objects including one or more of global variables, local classes, structure types, function modules, dynpros, and types from other packages.
