Update Invoice API

Introduction

Persists edits to an individual (or compatible) invoice header and lines. Parses invoiceData as InvoiceOriginal, applies service tax via calculateServiceTaxAmount, calls invoiceService.updateInvoice, deletes/re-saves InvoiceModel rows that meet content rules, resolves BookingDetails ref for single invoice type lines, logs activity.

Source: GenerateInvoiceAPI.updateInvoice.
