Abstract: A service request from a user is received to execute an operation on an instance of a business object. Thereafter, an access control check is performed to confirm whether the user is allowed to execute the requested operation on a type of business object corresponding to the business object specified and based on an access group associated with the user. Subsequently, the user is either provided with access to the instance of the business object to execute the operation if the access control check confirms that the user is allowed to execute the operation on the instance of the business object, or prevented from accessing the instance of the business object to execute the operation on the instance of the business object. Related apparatus, systems, techniques and articles are also described. Related apparatus, systems, techniques and articles are also described.

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.

Abstract: A data structure, such as a business object, is monitored to detect changes. Upon detection of the changes, a push service is initiated. Thereafter, the push service packages determines if such changes are relevant, and if so, data characterizing the save event in a message in a predetermined format. The message is later transmitted to an output management module so that the output management module initiates delivery of a notification message to at least one predetermined recipient by a predetermined communication channel. Related apparatus, systems, techniques and articles are also described.

Abstract: This invention relates to the necessary processes and application enhancements to provide customer extension functionality in terms of displaying additional data fields in a web application. When a message (310), describing the additional fields on header and/or item level by means of name-value pairs, is received, the additional fields are mapped into the database (250) of the business application. To get displayed the additional fields are mapped from the database (250) into an instance of a container class in the model component. By passing the instance of the container class from the model component to the view component, an HTTP response is created using the information provided by the instance of the container class. An HTML Browser (200) receiving the HTTP response displays the additional fields.
