Abstract: A system includes identification of editing of an active document by a user, and, in response to the identified editing, setting of enqueue locks on the active document, creating a draft document corresponding to the active document and an enqueue context associated with the draft document, storing the enqueue context with the draft document and attaching the enqueue context to a request session, determining an eTag of the active document and storing the eTag with the draft document, and associating the user with the draft document as its exclusive user.

Abstract: A service request to execute an operation on a business object is received. Thereafter, a metadata repository is polled to obtain a modeled association corresponding to the service request. The modeled association involves at least one node of the business object. The at least one node of the business object is then called using the modeled association to respond to the service request. Related apparatus, systems, techniques and articles are also described.

Abstract: A system may include acquisition of metadata defining a first object model, the first object model comprising an instance of a metaobject, acquisition of enhancement object metadata defining one or more enhancements to the first object model and associating each of the one or more enhancements with one of one or more stable anchors of the first object model, and creation, based on the metadata defining the object model and the metadata defining the one or more enhancements, of metadata defining an extended object model, the extended object model comprising an instance of the metaobject.

Abstract: Systems, methods, computer program products, and the like for performing business object service simulation are disclosed. A runtime model of a business object can be generated. The runtime model can include a plurality of structural and functional entities. A simulation runtime model of the business object can be instantiated. The simulation runtime model can include a plurality of pseudo-structural and pseudo-functional entities. During the simulation runtime model, a predetermined business object service of the business object can be selected and at least one parameter of the predetermined business object service can be determined. Functional entities of the runtime model can be replaced with pseudo-functional entities of the simulation runtime model. The simulation runtime model can be executed using pseudo-functional entities.
