BSIS & BSAS in S/4HANA

Compatibility viewFI-GL

Short answer

In S/4HANA, BSIS and BSAS are compatibility views, not tables. Every G/L line item lives in ACDOCA. Read ACDOCA (or the released CDS view I_GLAccountLineItem) — and take open-item status from BSEG, which still manages it. Don't extract from BSIS/BSAS.

What they were

In ECC, the General Ledger kept secondary index tables for speed: BSIS held open G/L line items, BSAS held cleared ones. They were indexed copies of the line items, by account.

What changed in S/4HANA

HANA aggregates on the fly, so the index tables aren't needed. The names live on as compatibility views; the data resolves to ACDOCA.

Object	Was	Now in S/4HANA
BSIS	G/L open-item index (table)	Compat view → ACDOCA
BSAS	G/L cleared-item index (table)	Compat view → ACDOCA
ACDOCA	—	Transparent table — every G/L line item
BSEG	—	Transparent table — manages open-item status

Querying BSIS/BSAS via SE16 can be slow and memory-heavy — the view rebuilds the old shape from ACDOCA and BSEG (SAP KBA 2793263). Read ACDOCA directly.

Where the fields went — BSIS to ACDOCA

BSIS / BSAS field	ACDOCA field	Meaning
BUKRS	RBUKRS	Company code
HKONT	RACCT	G/L account (now merged with cost element)
GJAHR	GJAHR	Fiscal year
BELNR	BELNR	Accounting document number
BUZEI	DOCLN	Line item (now 6-digit, no 999 limit)
DMBTR	HSL	Amount in local (company-code) currency
WRBTR	TSL	Amount in transaction currency
SHKZG	DRCRK	Debit / credit indicator
BUDAT	BUDAT	Posting date
KOSTL	RCNTR	Cost center (now on the line)
AUGBL	AUGBL	Clearing document

ACDOCA adds a ledger key (RLDNR) BSIS never had — always filter on one ledger, or the same document counts per ledger.

How to query it now

All G/L line items for an account · reads ACDOCA · parameterized

SELECT a.rbukrs, a.racct, a.belnr, a.gjahr, a.budat,
       a.drcrk, a.hsl, a.augbl AS clearing_doc
FROM   acdoca a
WHERE  a.rldnr  = '0L'                 -- leading ledger
  AND  a.rbukrs = :company_code
  AND  a.racct  = :gl_account
  AND  a.gjahr  = :fiscal_year;

Open vs cleared is not a clean ACDOCA filter. BSIS held only open items; in S/4HANA, open-item status is managed in BSEG, and a bare AUGBL = '' on ACDOCA over-counts (clearing semantics differ). For an open-item list, read BSEG or the released CDS view; use ACDOCA for the full line-item history.

Extract it compliantly

Method	Use when
Released CDS view + SLT	Bulk to a warehouse — the owned-layer path (I_GLAccountLineItem raw-data view)
Table / Table-CDC	Direct ACDOCA replication with delta
ODP-OData	SAP-sanctioned API, lower volume
SAP BDC / Datasphere Replication Flow	SAP-native pass-through (Delta Sharing)

Not ODP-RFC. SAP Note 3255746 prohibits third-party ODP-RFC extraction, and a June 2026 security patch blocks it.
