The 1C:University PROF can not be implemented without adjusting to the characteristics of a particular university. Together with new functionality problems of further maintenance, installation of new versions come. The use of well-proven rework practices does not always solve the problem, because it is impossible to change the typical supplier’s code without removing the configuration from support, and this will make it impossible to update fully automatically. It is the most difficult to splice changes after serious refactoring of the code from the supplier. If in the university there is no own specialist, this may cause rejection of improvements and a significant slowdown in implementation.In article the way of completion of functionality of a configuration without loss of a possibility of automatic updates, suitable for all modern solutions 1C is considered, including used in educational activity: 1C:University and 1C:University PROF, 1C:College, 1C:Educational Institution, 1C:Management of training center. Information is provided on the development of the capabilities of the configuration expansion mechanism and examples of improvements that can be implemented using this mechanism. The given examples are based on experience of implementation of projects of automation in the universities of the Ural Federal District.
