Mapping Table Inheritance Levels
As mentioned previously, you can configure many of the mapping tables for a specific institution. However, it is possible to share mapping information from the installation level via inheritance. This means that if an institution does not configure specific mapping information, the system will use the configuration information stored at the next higher level (such as the installation or OTB level).
For mapping tables, inheritance is provided at the table level, which indicates that the entire table (when configured at the institution level) applies to the specific institution, and no rows are inherited from a higher level.
