Add external code libraries to RBA when you want to use functions in a rule set that are only available in specific libraries (for example, a string-manipulation function).
RBA comes with several built-in code libraries. If you want to use additional libraries, you must provide them. Typically, you get libraries from Microsoft Visual Studio software or other programming software.
Imported code libraries apply to entire rule sets. They do not apply to a specific event-action pair, rule, or RBA as a whole. When you import a library, it is available for all of the parameters in the rule set, but it is not available in other rule sets.
To access a code library in RBA, place the library in a specific directory, open Parameter Code Editor, and click Imports.
If you want to learn which code libraries are available by default in RBA, click Imports and review the libraries in the System list.
