PMS AEAT SII Integration

This module connects the Property Management System with the Spanish AEAT SII tax reporting module. It changes one specific contact: the generic customer record used by PMS for simplified invoices (the "various" partner) is flagged as an anonymous cash customer, so that sales made to unidentified customers are reported correctly to the Spanish tax authority.

What changes for users:

• The generic PMS customer is automatically set as an anonymous cash customer for SII purposes when the module is installed.
• Odoo blocks any attempt to delete that generic customer. If a user tries, an error message appears saying the partner cannot be deleted.

Where it appears: there is no new menu or screen. The change is applied behind the scenes on the contact record and on the SII settings of that contact.

Which areas it touches: the contact model res.partner is extended, and the existing PMS generic customer record is updated. The module depends on the Spanish SII localisation and on the PMS property management modules, so it only makes sense when both are installed. No other models, reports, scheduled jobs or emails are added by this code.
