The Data Modeler is linked to version management, that is, versions are stored for each modeling object. An object can have a number of different versions. These are distinguished by an object status entry and a version number.
A detailed description of version management can be found in the documentation for the ABAP Dictionary.
Note that definitions cannot have more than one version and that previous versions cannot, therefore, be retrieved.
Before reloading a stored version, check whether the modeling object being retrieved fits the context of the existing relationships, specializations, and table/view assignments.
