The Company Code is the fundamental legal and accounting entity in SAP. For any financial transaction, including those within a project in Contract Accounting, a Company Code must be assigned as it represents the smallest organizational unit for which a complete, self-contained set of accounts can be drawn up.

The Percentage of Completion (POC) method based on costs is specifically designed for contracts where performance obligations are satisfied over time. It measures progress toward completion by comparing the costs incurred to date with the total estimated costs for the contract, which aligns perfectly with the described input method using costs incurred.

The Results Analysis (RA) report is the core standard report for analyzing and posting WIP, reserves, and revenue recognition. It calculates the values based on the configured revenue recognition method (e.g., POC) and provides the necessary figures for posting to Financial Accounting, making it essential for the month-end closing process in Contract Accounting.

Billing in contract accounting is typically dependent on recognized revenue. The Results Analysis (RA) run is the process that calculates and determines the revenue that can be recognized for a period (e.g., based on POC). Without running RA, the system lacks the necessary revenue recognition data to determine what amount can be billed, leading to the described error.

Settlement transfers costs (and sometimes revenues) from sender objects like projects to receiver objects. When settled to a profitability segment, the data flows into Controlling (CO), specifically into Profitability Analysis (CO-PA). This allows for management reporting based on dimensions like market segment, product, or customer, which is the primary purpose of CO-PA.

The original budget represents the first released budget for a project or WBS element. The overall budget is a calculated total that includes the original budget plus all approved budget supplements (additions) and budget returns (reductions). It shows the total funds currently available for the project.

In milestone billing, you can mark a milestone as ‘blocked for billing’. This allows the system to recognize the revenue (when Results Analysis is run) based on the achieved milestone, fulfilling accounting requirements. However, it prevents the automatic creation of a billing document, giving the business control over the timing of the invoice sent to the customer.

The Project Profile is a central master data setting that controls many aspects of a project’s behavior. Within its configuration, settings related to billing and revenue recognition (such as the billing method, revenue recognition method, and account assignment) are defined. This profile is assigned to the Project Definition, making it the primary link for managing financial aspects.

While VA01 creates the sales order (which could be a credit memo request order type), the actual billing document that reduces the accounts receivable and impacts revenue is created using transaction VF01. You would select the appropriate credit memo request document and reference the original project-related invoice to create the corrective billing document.
