Raw Data Interface

Definition

The Raw Data Interface (RDI) is an output routing mechanism that aggressively circumvents SAP’s internal visual layout rendering engines, choosing instead to output pure, unformatted structural data arrays explicitly designed for external digestion.

Business Purpose and Architecture

For massive utilities printing three million bills heavily laden with graphics, forcing S/4HANA to encode three million unique PDFs nightly will crash the spool servers. Architecturally, activating the RDI completely bypasses SAPscript PDF rendering. It dumps the doc_header and doc_item values into an ultra-fast raw flat-file spool. An external, dedicated third-party document processing engine (such as OpenText) digests this raw feed, instantaneously mapping it to proprietary graphical layouts optimized strictly for rapid physical mail sorting.
