Selector Mapping
Selector mapping provides a very flexible function, which is used to set what subjects should be listed in each of the subject selectors of the journal creation user interface. When creating new account book, it has already set the selector mapping for default subjects, you can input journal data directly. But if you have created new subjects, you must set selector mapping for the new subjects first, and then you can use them when inputting journal data. It is very easy to set selector mapping. In the first place select "Basic Data" -> "Subject Management" from the navigator on the left side, and then select "Selector Mapping" tab in the opened page, here we can set corresponding subject list for every subject selector, please see the picture below.

Firstly select a specific subject selector from "Tree View", and then select corresponding subjects from the subject tree, that's it.
