You need to configure sales invoicing.

In BC, invoices can be generated from:

Sales Order Invoicing (D): Post invoices directly from sales orders.

Combine Shipments (A): Consolidate multiple shipments into a single invoice (used for customers who require weekly or monthly invoices).

Get Shipment Lines from Sales Order (B) is incorrect — shipment lines are retrieved in warehouse processing, not for invoicing.

Sales Order Shipping (C) posts shipment only, not invoices.

Get Shipment Lines from Sales Invoice (E) is used for service scenarios but is not the standard sales invoicing process here.

Correct: A and D
