InvoicingSimulation## Definition

InvoicingSimulation in SAP Utilities acts as a test execution of the Invoicing process, grouping simulated or actual un-invoiced billing documents together to create a preview of the final Print Document. It evaluates cross-account functions like budget billing calculations, taxes, late payment interest, and existing open items without posting the results to financial accounting (FI-CA).

Business Purpose and Architecture

Utilities utilize Invoicing Simulations to verify how the customer’s final bill will look when multiple services, adjustments, and historical open items are convergent on one page. Its architecture interacts at the Contract Account level rather than the individual contract level. By pulling in simulated billing documents and checking them against Dunning and clearing controls, businesses can validate complex, multi-divisional invoices (e.g., electricity, water, and internet combined) safely before real documents are generated.
