Validate field names in the XML definition

When saving a Payroll Export Task, the field names in both <field> and <dummy_field> elements are validated against system-defined properties. Field names that start with reserved prefixes, such as job_, dept_, and tcode_, must match valid data properties. Otherwise, the task cannot be saved and an error is displayed.

The system also validates <field> elements that do not use reserved prefixes to ensure that they exist as columns in the payroll export database views. This validation does not apply to <dummy_field> elements or fields with reserved prefixes.

To avoid validation errors, use custom field names that do not begin with reserved prefixes and update all related references when renaming.
