Abstract

Methods and systems to include transformation nodes in a business system are provided. A transformation node may provide controlled redundancy of data within the business object hierarchy. Transformation nodes may store data from core nodes without persistency, and permit different data presentation modes than for the core nodes. When a service call is placed to a transformation node, the transformation node may call corresponding services from associated core nodes.

Claims

1. A method of updating information displayed in a user interface, comprising:

responsive to a request for properties describing a transformation node, requesting properties describing a core node associated with the transformation node;

responsive to receiving properties of the core node, mapping the properties of the core node to properties of the transformation node;

performing an exit operation to modify data to be sent to the user interface;

sending the properties of the transformation node to the user interface; and

updating the user interface element associated with the transformation node to display the new information.

2. The method of claim 1, wherein the exit operation is a pre-exit operation performed prior to receiving properties of the core node.

3. The method of claim 1, wherein the exit operation is a post-exit operation performed after receiving properties of the core node.

4. The method of claim 1, wherein the transformation node is derived from the core node.

5. A system for accessing a business management system, comprising:

a model-driven user interface to construct user interface elements based on services exposed by nodes;

a plurality of core nodes, each core node exposing a service of a backend application;

a transformation node derived from a first of the plurality of core nodes; and

an enhancement layer of the transformation node to provide modification data associated with elements of the user interface.

6. The system of claim 5 wherein the transformation node includes data stored in a second core node.

7. The system of claim 5 wherein the transformation node includes a service exposed by a second core node.

8. A machine-readable medium containing program instructions for execution on at least one processor, which when executed by the processor cause the processor to perform:

responsive to a first request generated from a first model-driven user interface, sending the first request to a transformation node associated with the first interface;

selecting a core node associated with the transformation node;

defining a second request based on the first request and the core node;

performing an exit operation to modify the second request;

sending the second request to the core node;

executing the second request; and

updating the first user interface to reflect changes resulting from execution of the second request.

9. The machine-readable medium of claim 8, wherein the exit request is a pre-exit operation.

10. The machine-readable medium of claim 8, wherein the exit request is a post-exit operation.
