In one embodiment, a proxy transactional context corresponding to a transactional context of a first software solution unit is generated. Further, a business object of a second software solution unit corresponding to the proxy transactional context is retrieved. Furthermore, the assignment of the retrieved business object to a business object of the first software solution unit is defined and the defined assignment is stored in the proxy data object. The proxy transactional context may be accessed using a remote function call and upon executing the proxy transactional context, the program returns to the transactional context. Thereby, the first software solution unit is integrated with the second software solution unit without disrupting the transactional context of the first software solution unit.
