Convergent Invoicing (CI) in SAP is a centralized billing solution that consolidates invoicing for various services (telecom, utilities, subscriptions) into a single document. While powerful, it can encounter errors during processing. This article explores common CI errors, their root causes, and step-by-step solutions.
