[FR] Line Item Export

Problem statement

In InvenTree 0.x there was an export plugin called “Line Item Export”. It allowed exporting line items for purchase orders and sales orders (order lines, quantities, references, pricing, etc.) into a structured export format for downstream processing.

After migrating to InvenTree v1, this functionality appears to be missing. We rely on line-level exports for integrations and reporting, and the existing order exports do not fully replace this use case.

Questions:

Does an equivalent solution already exist in InvenTree v1 (core or plugin)? Where can I find it?

If not, is line-item–level export functionality planned or discussed on the roadmap?

Is there a preferred architectural approach for reintroducing this as a plugin in v1?

Any pointers to existing work, discussions, or design guidance would be useful.

Example of an older export we could track down PurchaseOrderLineItem-2025-xx-xx.xlsx:

edit:
I again talked to my co-worker and with the help of a docker v0.17 inventree he showed me what was used.
It was: http://inventree.localhost/admin/order/purchaseorderlineitem/ . IIRC this is just some UI on top op the database model. Not really an export plugin. My question is still "is this possible" but is perhaps not 100% talking about the right place.

In any given table, select the "download data" button to export the data to file:

[Mattie112]

Yes, but that exports all Line Items of a single PO for example. My co-worker has the need to export ALL line items of all PO (for a certain date range but that is an easy filter after the fact).

Is that also possible?

[SchrodingersGat]

Yes, that is possible, all data export is performed via the API. You can look at the network request made when you hit "export" in the dialog, and simply removing the ?order=<ID> filter:

So, something like:

http://localhost:8000/api/order/po-line/?export=true&export_plugin=inventree-exporter&part_detail=true&export_format=csv&export_plugin=inventree-exporter
