Adding codes
You can add new codes to an imported code source by creating a text file containing the list of custom codes. Each code must be defined in a new line and use a field separator, ^ in the code definition. The following format must be used to define the code:
code1^shortdescription1^longdescription1
code2^shortdescription2^longdescription2
where, shortdescription and longdescription are optional parameters.
To add custom codes to an imported code source
1. Click View on the left pane of the Code Sources page.
The View page with a list of imported code sources is displayed on the right pane.
2. On the View page, click the icon 
under the Action column of a code source. The Custom page is displayed in the browser window which contains a Browse and an Add button.
3. Click Browse to navigate to the text file that contains the custom codes to be added.
4. Click Add.
The new codes are added to the code source and can be viewed on the Codelist page.
Note:
If the text file contains a code that already exists in the imported code source, a detailed error message is displayed on the Custom page and the new codes in the file will not be added to the code source.
