MRP v2 exporter¶

Integrates with the MRP accounting system REST API (Czech). There are two separate managers — one for issued invoices and one for received invoices — because the MRP API endpoint and document structure differ between the two origins.

Each manager exposes two admin actions:

An XML file export (email delivery, same as v1).
A direct API push to the MRP server.

Configuration¶

Both managers require API_URL.

INVOICING_MANAGERS = {
    "invoicing.exporters.mrp.v2.managers.MrpIssuedManager": {
        "API_URL": "https://your-mrp-instance.example.com/api/",
    },
    "invoicing.exporters.mrp.v2.managers.MrpReceivedManager": {
        "API_URL": "https://your-mrp-instance.example.com/api/",
    },
}

Admin actions¶

MrpIssuedManager¶

Action name	Label	Description
`mrpissuedmanager_export_list_issued_mrp`	Export issued to MRP v2 (XML)	Generates XML and delivers by email
`mrpissuedmanager_export_via_api`	Export issued to MRP (API)	POSTs invoices directly to the MRP API

Origin restriction

MrpIssuedManager only accepts invoices with origin=ISSUED. Mixing issued and received invoices in the same export will produce a validation warning and abort.

MrpReceivedManager¶

Action name	Label	Description
`mrpreceivedmanager_export_list_received_mrp`	Export received to MRP v2 (XML)	Generates XML and delivers by email
`mrpreceivedmanager_export_via_api`	Export received to MRP (API)	POSTs invoices directly to the MRP API

Origin restriction

MrpReceivedManager only accepts invoices with origin=RECEIVED.

API export internals¶

The API export path uses outputs.models.Export with output_type=OUTPUT_TYPE_STREAM and delegates to a Celery task (invoicing.exporters.mrp.v2.tasks.send_invoices_to_mrp). Make sure Celery is configured and running for API exports to work.

Invoices are processed one by one. If a particular invoice fails XML generation or XSD validation, it is skipped, marked as a failure, and included in the summary email, while the rest of the invoices continue to be sent. Only fatal errors (for example, missing exporter configuration) abort the whole export; in that case the export is marked as failed and the email contains the fatal error message.

Exporter classes¶
