Technical 1:1 migration from R/3 ERP to S/4HANA in 2021 (Brownfield).
Continued operation of ECCS for over 4 years since the switch to S/4HANA.
The special ledger KVL (group preparation ledger) was used for mapping/enriching the accounting data for consolidation.
Management financial statements were prepared monthly. Legal financial statements were prepared annually.
Data model (ECCS) from 2010
Separate legal and management financial statements are prepared in different versions, sometimes with different positioning plans in the ECCS.
Project Challenges
Integration of legal and management financial statements into a single version with a position plan
BW remains the central reporting platform for consolidated reporting at the operational and consolidated levels - interface setup
For certain items, only reporting of the final balances is possible (e.g., provisions) – workaround with adjustment postings on separate document types to reflect the mirror data for all necessary items.
No replacement of the existing KVL (consolidation preparation ledger) due to the existing booking processes in the upstream systems.
In the EC-CS process, the balance carryforward movement types are not write-protected (the upload process must be agreed upon).
