Post-load reconciliation that proves the data in Oracle Fusion matches SAP S/4HANA exactly. Trial balance per BUKRS-to-BU, AP/AR aging, fixed-asset register, period reconciliation, multi-currency, parallel ledger. German HGB/IFRS audit pack auto-generated.
The audit signature on year-end accounts depends on it. The HGB/AO 10-year retention obligation depends on it. The CFO's professional reputation depends on it.
Every SAP S/4HANA to Oracle Fusion migration eventually meets the same question from internal audit: 'Prove the trial balance in Fusion equals the trial balance in S/4HANA at cutover.' If the answer is 'we did our best to match, here are some spreadsheets,' the audit conversation goes badly. If the answer is 'here is the cryptographically-signed, time-stamped reconciliation pack covering every period, every BU, every account, with the hash of every migrated row,' the conversation ends quickly.
Syntra ETL's data validation engine produces the second answer by design. Every record extracted from S/4HANA is hashed at source. Every record landed in Fusion is re-hashed and compared. Counts, sums, and hashes are independently reconciled per partition. The output — the reconciliation pack — is the artifact the SOX control owner, the Big Four external auditor, and the BMF tax inspector all expect to see.
The validation engine runs continuously: in every UAT dry run, in every parallel-close cycle, and in the production cutover. By the time cutover Saturday completes, the reconciliation pack is already signed and on its way to internal audit. There is no anxious week of 'reconciling the migration' afterwards — that work happens automatically as data lands.
Each domain reconciles independently and contributes to the unified audit pack. Variance threshold per domain: 0.00.

Transaction-currency, local-currency, group-currency views all independently reconciled. Parallel ledger (IFRS + local GAAP) reconciled separately — both must match.
Validation runs continuously through dry runs, parallel close, and production cutover. The audit pack assembles incrementally.
S/4HANA trial balance, AP aging, AR aging, asset register, inventory snapshot captured per BUKRS per period. SHA-256 hashes computed per partition. Baseline manifest signed and time-stamped.
Every record hashed at extract time. Partition manifests assembled with row counts, sum totals, hash signatures. Discrepancies vs source baseline surface immediately — typically caused by mid-extract postings.
Crosswalks applied, account-assignment collapse executed. Pre-load checks: every record has a valid mapping, no orphaned references, all reference data present in Fusion target. Errors logged with row-level diagnostics.
ESS job status monitored, errors captured per row, Fusion-side checksums computed. Per-load reconciliation: counts loaded vs counts submitted, sum totals match, hash signatures match. Failures route to error-handling queue.
Full reconciliation pack generated: trial balance per period per BU, AP/AR aging per bucket per vendor/customer, asset register per asset per book, inventory value per item per org, multi-currency views, parallel-ledger views.

SAP S/4HANA data validation is the post-load reconciliation work that proves the data landed in Oracle Fusion exactly matches what was extracted from SAP S/4HANA — to the cent, to the row, and to the cryptographic hash. Validation runs at three layers: counts (number of journal lines, suppliers, customers, items, open POs), sums (total debits, total credits, AP balance, AR balance, asset NBV by book, inventory value by org), and hash signatures (cryptographic checksums per partition for tamper evidence). The output is a signed reconciliation pack: S/4HANA trial balance per BUKRS vs Fusion trial balance per BU, AP aging vs AP aging, AR aging vs AR aging, asset register vs asset register. Internal audit signs the pack directly. This is the German HGB/AO and SOX evidence base.
The validation engine runs in two phases. Phase 1 (pre-load): every record extracted from S/4HANA is hashed at source — typically SHA-256 of a canonical field concatenation per row. Row counts and sum totals per partition (typically partitioned by BUKRS and fiscal period) are captured in a manifest. Phase 2 (post-load): every record landed in Fusion is re-extracted from Fusion via REST API or BI Publisher report, re-canonicalised, re-hashed, and compared row-by-row, partition-by-partition. Any record that doesn't match is flagged with the exact field-level diff. Counts and sums are independently compared. The reconciliation report is auto-generated, time-stamped, signed by the migration platform, and stored in an immutable audit log for the full HGB/AO 10-year window.
Trial balance reconciliation runs per ledger, per company code (S/4HANA BUKRS → Fusion BU), per fiscal year, per period, per account. The source side queries ACDOCA (or BKPF/BSEG legacy) aggregated by RACCT (GL account), RBUKRS, RYEAR, POPER. The target side queries Fusion GL_BALANCES (or runs the BI Publisher Trial Balance report). Period-by-period, the reconciliation must match to the cent — debits to debits, credits to credits, period activity to period activity, closing balance to opening balance plus net activity. Any variance, no matter how small, is captured in an exception report with the specific account, period, and amount. The reconciliation auto-incorporates inter-company eliminations, multi-currency accounting, and parallel-ledger postings for IFRS-on-leading customers.
AP aging reconciliation: source side queries S/4HANA BSIK (open vendor items) and BSAK (cleared vendor items) aggregated by LIFNR (vendor), BUKRS, and aging bucket (0–30, 31–60, 61–90, 90+ days from BSIK.NETDT net due date). Target side queries Fusion AP_INVOICES_ALL filtered to open status, aggregated by SUPPLIER_ID, BU_ID, and aging bucket using DUE_DATE. The two aging reports must match per vendor, per BU, per bucket. AR aging follows the equivalent pattern from BSID/BSAD to Fusion RA_CUSTOMER_TRX_ALL. Validation pays particular attention to partial-paid invoices (where the open balance differs from the original invoice amount) and to credit memo netting (Fusion handles credit memos as separate transactions; S/4HANA can net them at clearing time).
Fixed-asset register reconciliation runs per asset, per book (S/4HANA depreciation area → Fusion asset book), per period. The source side queries S/4HANA ANLA (asset master), ANLB (asset book values per depreciation area), and ANLC (cumulative values by year). The target side queries Fusion FA_ASSET_HISTORY and FA_BOOKS. For every asset, the reconciliation compares: cost (acquisition value), accumulated depreciation, NBV (net book value), in-service date, useful life, depreciation method. Variances are flagged at the asset level. The depreciation-key crosswalk is validated by running a single period's depreciation in both systems and comparing line by line. Asset CIP (construction in progress) balances reconcile separately because Fusion treats them differently from in-service assets.
S/4HANA carries up to three currencies per posting (transaction WAERS, local DMBTR, group amount), with currency translation occurring at posting time per OB22 configuration. Fusion carries entered currency, accounted currency (the BU's ledger currency), and reporting currency through reporting-currency conversion at GL_BALANCES level. Period reconciliation validates all three currency views: at the transaction-currency level (BSEG.WRBTR per WAERS must equal Fusion GL_JE_LINES.ENTERED_DR/CR per currency), at the local-currency level (BSEG.DMBTR must equal GL_JE_LINES.ACCOUNTED_DR/CR), and at the reporting-currency level after translation. For dual-ledger customers running IFRS plus local GAAP in parallel, the reconciliation runs separately per ledger — both must match independently.
The audit pack is the deliverable that goes to internal audit, external audit (typically a Big Four firm signing the year-end accounts), and ultimately to the BMF (Bundesministerium der Finanzen) if a tax audit references the migration period. Contents: full trial balance reconciliation per BUKRS-to-BU per period (PDF + CSV); AP aging reconciliation; AR aging reconciliation; fixed-asset register reconciliation; multi-currency translation reconciliation; parallel-ledger reconciliation (IFRS vs HGB) if dual-ledger; exception log with the resolution for every variance, no matter how small; cryptographic hash manifest per migrated table with time-stamped signatures; mapping repository PDF; and the sign-off matrix showing every artifact and the role/date of its sign-off. The pack is delivered as a single bundled PDF plus the underlying CSVs, and the immutable hash signatures persist for the full HGB/AO 10-year window.
Yes — that's the primary purpose of dry-run validation in non-prod environments. Every dry run produces a full reconciliation pack against the equivalent S/4HANA dataset, and the engine surfaces variances before production cutover. Common pre-cutover catches include: cost-centre-to-segment-value mismatches caused by missing crosswalk entries; vendors/customers blocked by Fusion duplicate-check rules; items rejected by Fusion item-class validation; journal lines failing intercompany balance because a missing IC partner mapping; assets failing depreciation due to a method-code crosswalk gap; multi-currency posting failures due to wrong currency-translation type. Catching these in dry-run UAT means cutover Saturday runs to plan — the validation engine is what turns 'we hope it works' into 'we know it works to the cent'.
