Export interface framework

This export process is common to all application standard export interfaces.

Exporting application data is divided two steps, both of which occur in one scheduled task:

1. Optionally, export data from application tables to the WBINT_EXPORT staging table.
2. Export data from application tables (if previous step is skipped) or from the WBINT_EXPORT staging table to an external data file.

The export task is configured and scheduled through the application Job Scheduler, which enables the task to export data from the application at a pre-defined schedule.
