Business Logic Task Handler API Overview

The Business Logic Task Handler API lets you perform custom business logic during data validation operations for the current task, for example:

• Validating customer-specific task screen fields (for example, the value of an Employee ID field must exist in the master Human Resources database).
• Enforcing custom business rules (for example, an administrator cannot be allowed to manage more than five groups).

A business logic task handler (BLTH) can be implemented in Java or server-side JavaScript.
