Purpose of the Module:
======================

As part of the SII requirements (Legal requirement in Chile),
beginning on March 2021 boletas transactions must be sent to the SII under the
electronic workflow using a different web service than the one used for electronic Invoices.
Previously, there was no need to send the boletas to the SII, just a daily report.

Additionally of sending the Boleta individually (with the EDI workflow),
at the end of the day, a daily summary with all the Boletas transactions
should be sent to the SII – electronically (also a legal requirement).
This is called “Libro de ventas diarias” (former “reporte de consumo de folios” or RCOF).

Differences between Electronic boletas vs Electronic Invoicing Workflows:
=========================================================================

These workflows have some important differences that lead us to do this PR with the specific changes.
Here are the differences:

* The mechanism for sending the electronic boletas information needs dedicated servers, different from those used at the reception electronic invoice (“Palena” for the production environment – palena.sii.cl and “Maullin” for the test environment – maullin.sii.cl).
* The authentication services, querying the status of a delivery and the status of a document will be different.
* The authentication token obtained
* The XML schema for sending the electronic boletas was updated with the incorporation of new tags
* The validation diagnosis of electronic boletas will be delivered through a “REST” web service that has as an input the track-id of the delivery. Electronic Invoices will continue to receive their diagnoses via e-mail.
* The track-id (“identificador de envío”) associated with the electronic boletas will be 15 digits long. (Electronics Invoice is 10)
