When you create a mapping rule, its type is determined by the input and output attributes that you select. For example, if the input and output attributes are compatible primitive types, such as strings or integers, a move mapping rule is specified. If the input and output attributes are complex types, a submap rule is specified. If neither move nor submap are appropriate mapping rule types, a custom mapping rule is specified.
You must have a mapping model open. A mapping model has .mapping as a file name extension. The mapping model must contain at least one map.
); then click the appropriate mapping rule type. The editor
area displays only the valid mapping rule types.
