Software extensions for applications of an enterprise system may be developed in a test system. An adaptation transport module displays, in a test system, a plurality of semantic representations of software extension components for an application of an enterprise system. A semantic representation of a software extension for the application is generated based on a user selection of a combination of the semantic representations of software extension components. An adaptation object comprising the semantic representation of the software extension and at least one associated software object is generated by identifying the associated software object(s) based on an adaptation type of the adaptation object. The adaptation transport module displays, in the enterprise system, the semantic representation of the software extension (or of a collection including the software extension) and the adaptation object is imported to the enterprise system based on a user selection of the semantic representation of the software extension.
