💰 Clean Core Financial Extensibility

SAP Universal Journal (ACDOCA) & Finance Architect

Design upgrade-stable financial enhancements for SAP S/4HANA. Replace legacy BSEG/BKPF substitutions with FINS_ACDOC_POSTING_EXTENSION, CDS Extension Views, and RAP I_JournalEntryTP.

⚡ S/4HANA Financial Architecture Rule

Modifying legacy tables (BSEG, BKPF) directly or using classic user exits (RGGBS000, OBBH, OB28) breaks the Single Source of Truth in S/4HANA. All clean core financial enhancements must write to ACDOCA through released developer BAdIs and extend standard financial CDS views via I_JournalEntryItem.
