Service Tasks are used to execute code defined in SHAR services.

The inputs to a Service Task are the result of the “Input Mapping” expressions. These transform Process Variables into service task local variables.

The outputs of a Service Task are the result of the “Output Mapping” expressions. These transform output variables into Process Variables.

Using input and output mappings allow you to define reusable tasks that are agnostic of the terminology used in the process.

eg. Your process may have a field called “UserID” which contains the email address of the user, but your email service task is expecting a field called “EmailAddress”. Mapping allows both to be named semantically but used interchangeably.
