Creating and adding repository function
Repository Functions are reusable Java functions (UVJ and UBJ) stored in Function Repository which is part of a Mapper database. Reusable functions can be dropped on a mapping or a loop. See Function elements overview.
Note: When connecting elements, the Mapper Editor will allow you to
drop elements only where it is acceptable.
Before you start, you must define a Mapper Database connection to be able to use repository functions.
