The Load Custom Data Type Mapping Set menu option enables you to load a custom data type mapping set from an XML file into the RED metadata repository.
To load a data type mapping set, select Tools > Data Type Mappings > Load Custom Data Type Mapping Set.
The following window is displayed. Select the XML file to load the data type mapping set. By default, RED expects the XML files to be in the ProgramData\WhereScape\Work directory.
