1. A computer program product comprising a machine-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising: generating a runtime model of a business object, the runtime model comprising a plurality of structural entities and a plurality of functional entities; instantiating a simulation runtime model of the business object, the simulation runtime model comprising a plurality of pseudo-structural entities and a plurality of pseudo-functional entities; selecting, during the simulation runtime model, a predetermined business object service of the business object and determining at least one parameter of the predetermined business object service; replacing, during the simulation runtime model, the plurality of functional entities of the runtime model with the plurality of pseudo-functional entities of the simulation runtime model; and executing, by the at least one processor, during the simulation runtime model, the simulation runtime model using the plurality of pseudo-functional entities.
