The purpose of this document is to outline the conversion approach for migrating Trial Balance – Prior Year (TB PY) data into SAP S/4HANA.
This dataset represents the opening balances for FY2026 (for Group 1 company codes) and FY2027 (for Group 2 company codes).
The legacy trial balance data includes document currency, local currency, and group currency amounts. All currencies will be migrated accordingly, unless there are design changes affecting local or group currency configurations.
Exchange rates will be applied based on historical posting rates for each period end.
This document outlines the approach for converting Trial Balance – Current Year (TB CY) data from legacy source systems into SAP S/4HANA, in alignment with the target design and migration strategy.
Relevancy criteria:
As per the current implementation plan, there will be two separate go-live waves:
Group 1: Go-live on 1st July 2028
TB migration scope: 1.5 years of balances, starting from the Opening Balance as at January 2027 ( Only balance sheets including retained earning account ). It will be posted on the last day of the prior year’s final posting period, followed by a carry-forward. Therefore, The opening balances for January 2027 will be migrated as the closing balances from 2026 after the execution of a balance carry-forward by the business.
Group 2: Go-live on 1st January 2029
TB migration scope: 1 years of balances, starting from the Opening Balance as at January 2028 ( Only balance sheets including retained earning account ). It will be posted on the last day of the prior year’s final posting period, followed by a carry-forward. Therefore, The opening balances for January 2028 will be migrated as the closing balances from 2027 after the execution of a balance carry-forward by the business.
Basic Selection criteria from source table GLT0:
| Field (GLT0) | Selection rule | Details |
|---|---|---|
| BUKRS | Company codes in scope | Based on Grp 1 and Grp 2 in scope maintained in ADM construct page |
| RLDNR | 0L (or leading ledger in ECC) | S/4 expects leading-ledger–based balances |
| RYEAR | Last two closed fiscal years | For Grp 1 go-live, RYEAR in ( 2027 , 2028 ) For Grp2 go-live, RYEAR in ( 2028 ) |
| RRCTY | 0 (actuals) | RRCTY = '0' as migration is required for actual. |
Exclusion: Balances for local accounts will be excluded from IFRS TB migration ( scope of this spec ). A Data Construction Sheet ( as shown below) will be created to list all local accounts, enabling their exclusion from the leading ledger migration. The migration of balances for local accounts will be described in their relevant specs 9014 and 9016.
| Source System | Account Number | Account Type |
|---|---|---|
| PF2 | Local | |
| WP2 | Local | |
| PI2 | Local |

Note: The balance sheet balances of the closed fiscal year will be posted and Balance Carry Forward (BCF) to be done after load in the S4HANA. No BCF is needed if the balances are loaded as opening balances at the beginning of the year.
Accordingly, the migration posting dates for opening balances will be as follows:
For January 2027, posting date: 31st December 2026
For January 2028, posting date: 31st December 2027
| Source | Scope | Source Approx No. of Records | Target System | Target Approx No. of Records |
|---|---|---|---|---|
| PF2 | TB PY | N/A | S4HANA | N/A |
| WP2 | TB PY | N/A | S4HANA | N/A |
| PI2 | TB PY | N/A | S4HANA | N/A |
The Balance Sheet migration approach will vary depending on the type of General Ledger (GL) Account, as outlined below:
Non–Open Item Managed Balance Sheet Accounts
Open Item Managed Balance Sheet Accounts
Reconciliation (Control) Accounts, including Inventory Accounts
The migration of Balance Sheet account balances will be executed in two stages:
Opening Balances
Opening balances will be migrated to establish the financial position at the start of the target fiscal year.
For Group 1 company codes, the migration will be based on balances as at 31st December 2026, and for Group 2 company codes, as at 31st December 2027, in line with the current go-live schedule.
Note: Although this document references the trial balance migration across all periods, it specifically focuses on the opening balance migration. The carried-forward balances from the legacy system will form the opening balances, which will be posted using the last day of the preceding fiscal year, followed by a balance carryforward process.
Group 1: The carried-forward balances from FY 2027 will form the opening balances and will be posted with a posting date of 31st December 2026.
Group 2: The carried-forward balances from FY 2028 will form the opening balances and will be posted with a posting date of 31st December 2027.
Year-to-Date (YTD) Periodic Movements
Monthly balance movements will be migrated progressively up to the following cut-off periods:
Group 1 company codes: up to 30th June 2028
Group 2 company codes: up to 31st December 2028
This approach ensures that all interim financial movements are accurately reflected in the target system up to the designated migration period for each group.
For each period within scope, Trial Balance (TB) data will be migrated as life-to-date balances, with the posting date set to the last day of the respective period.
For all accounts except Retained Earnings accounts, Life-to-Date (YTD) periodic movements will be derived by combining the opening balance with year-to-date balances. The year-to-date balances will be calculated by accumulating all transactional postings (BSEG) for each period up to and including the target migration period.
For Retained Earnings accounts, as listed below, Life-to-Date (YTD) periodic movements will be calculated solely by accumulating all transactional postings (BSEG) for each period up to and including the target migration period, excluding the opening balance.
| Source System | Chart Of account | RE Account Number | Type |
| PF2 | COCA | 3042000000 | Global |
| PF2 | COCA | C042000000 | Local |
| WP2 | Z001 | 12800320 | Global |
| WP2 | Z001 | 12800600 | TBC |
| WP2 | Z001 | 81280032 | Local |
| PI2 | COCA | 3042000000 | Global |
| PI2 | COCA | C042000000 | Local |
For each period in scope, TB data will be migrated as life-to-date balances with the posting date set to the last day of the respective period.
These entries will be reversed using mass reversal (T-code F.80) on the first day of the subsequent period. Risks will be minimised by selecting individual entities during the reversal process, ensuring that no incorrect company codes or fiscal periods are reversed accidentally.
This approach ensures that open item managed lines are automatically reversed and cleared for all periods up to (but not including) the go-live period.
Approach of Migration of Balances of Sub-Ledger or Reconciliation Accounts:
Approach of Migration of Balances of Open-Item Managed GL Accounts:
During go-live (posting date = cutover date), balances of open item–managed accounts ( Included in CNV-9010 GL Open Items) will be migrated into GL take-on account 5310998 (in place of the actual accounts) as part of the Trial Balance migration process. GL take-on account 5310998 is the same account as Trial Balance offset account
Subsequently, CNV-9010 GL Open Items will be migrated with offset lines recorded in the trial balance offset account 5310998, ensuring alignment between the trial balance and open item data.
This ensures data accuracy and prevents duplicate or additional open items requiring clearing.
Note: The migration of GR/IR open item balances will be posted to the designated take-on accounts, while the cutover approach for transferring these balances to the actual GR/IR accounts (most probably into some manual GR/IR account ) is still pending finalization by the S2P stream.

For non–cut-over periods, multiple take-on accounts—"based on the GL Account Mapping for Migration"—will be used for the various sub-ledger types. However, during the cut-over period, only one designated account will be used for each individual sub-ledger (as listed below). Syniti team will need to apply right logic in the transformation to take care of this. Refer to Transform section for the field HKONT.

Note: The migration GL account mapping will specify the mapping details for each sub-ledger type during non cut-over periods. A separate GL account mapping will be used to define the mapping details for each sub-ledger type specifically for the cut-over period.

In the SAP ECC system, parallel accounting was implemented using the account-based approach. But, In the SAP S/4HANA target system, parallel accounting is instead managed through the ledger-based approach using multiple ledgers.
The account-based approach was implemented differently across the source systems, specifically in PF2 and WP2.
In the case of PF2, parallel accounting was handled by performing reversal postings to designated contra accounts, followed by repostings to the corresponding local (main) accounts. This approach allowed the system to maintain multiple accounting perspectives on the same transactions while ensuring that the balances in local accounts accurately reflected the intended financial position.
e.g

In SAP S/4HANA, parallel accounting is implemented using a ledger-based approach. In this approach, each accounting principle is assigned to a dedicated ledger, establishing a 1:1 relationship between ledgers and accounting principles.
TB migration strategy involves converting the existing classic G/L (based on the account approach) to the new G/L.
For the example provided, the migration will be executed into the Local GAAP and IFRS ledgers, in accordance with the sample data presented in the ECC system illustration.

In the case of WP2, parallel accounting was handled by performing Delta postings to the corresponding local (main) accounts. This approach allowed the system to maintain multiple accounting perspectives on the same transactions while ensuring that the balances in local accounts accurately reflected the intended financial position.

Separate conversion specs describe the migration of balances into local accounts. To maintain simplicity, A Data Construction Sheet will be created to list all local accounts, enabling their exclusion from the leading ledger migration. The migration of balances for local accounts will be described in the following two conversion specifications:
In general, account numbers (Legacy SAKNR from the source tables) that begin with an alphabetic character (A–Z) are considered Local Accounts and should therefore be excluded from the IFRS trial balance migration.
The Trial Balance migration executed through the object ‘CNV-9015 TB PY’ will post values to both the IFRS and Local (LG) ledgers. Subsequently, the Local Ledger (LG) will be migrated again using ‘CNV-9016 TB PY (Legal Val – Local GAAP)’, which will recalculate the legacy local account balances and adjust for the amounts already posted via ‘CNV-9015 TB PY’.
With Functional input, document the technical design of the target fields that are in the scope of this document.

The extraction of General Ledger (GL) balance data from the source system will be performed using one of the following approaches:
Option 1 – Ledger-Based Extraction:
Periodic balances of General Ledger (GL) accounts will be extracted directly from the GLPCT and GLT0 tables. This approach is recommended when the ledger tables provide a complete and reconciled view of financial balances as of the cut-over date.
In the legacy systems (ECC – PF2, WP2, and PI2), document splitting and profit centre balancing functionalities are not enabled. As a result, only Profit and Loss (P&L) account balances are available at the profit centre level within the ledger tables.
Accordingly:
Balance Sheet account balances will be extracted from GLT0, as these balances are not maintained in GLPCT.
P&L account balances will be extracted from GLPCT, where profit centre-level balances are available.
The combined dataset from GLPCT and GLT0 will provide a complete representation of all account balances required for migration.
It should be noted that records extracted from GLPCT contain profit centre information, whereas records from GLT0 do not. Consequently, a significant number of account lines will not include profit centre details. These lines will need to be managed either by assigning default profit centres or by allocating balances based on subledger-level data to ensure accurate profit centre reporting in the target system.
Note: WP2 does not have trial balance maintained in the profit centre level and thus, there is no data in GLPCT.
Since this CS pertains to the opening balance, and the opening balance includes only balance sheet data, only GLT0 is relevant for extraction within the scope of object number 9015.
Option 2 – Transaction-Based Extraction:
All transactional line items will be extracted from the BSEG table and subsequently aggregated at the relevant key field level — Company Code, GL Account, Posting Period, Fiscal Year, Profit Centre, Cost Centre, and Transaction Currency — to derive the General Ledger (GL) balances.
This approach is suitable in scenarios where a detailed reconstruction of balances is required, or where ledger tables are not fully aligned with the underlying transactional data.
Additionally, this method enables the generation of Trial Balances that include both the key financial attributes (such as Company Code, GL Account, Period, Fiscal Year, Profit Centre, Cost Centre, Transaction Currency) and extended analytical dimensions (such as Transaction Type, XREF1, XREF2, etc.), thereby providing enhanced traceability and reconciliation capability.
Recommended Approach for S/4HANA Migration for TB-PY ( Opening Balance )::
For migration to S/4HANA, the ledger-based extraction approach (Option 1) is recommended. This method ensures alignment with the source system’s reconciled balances, simplifies reconciliation during cut-over, and provides a structured foundation for subsequent profit centre enrichment where required. The transaction-based extraction (Option 2) may only be considered in exceptional cases where ledger balances are incomplete or reconciliation discrepancies are identified and balances are needed at the additional attribute level like transaction type. As this option involves processing a extremely large volume (200 Million)of data, it should be pursued only after thorough evaluation and justification and need agreement with technical team.
Note: Since this CS pertains to the opening balance, and the opening balance includes only balance sheet data, only GLT0 is relevant for extraction within the scope of object number 9015.
Note: for Each GL open line in scope of migration, an offset line to be created with the same GL Account.
In Migration cockpit, offset account number field is set in the same line and therefore, it will create offset line on its own. So, transformed data will be one line for each legacy in-scope line but will be automatically created with an offset line.
Posting Date ( which is generally the cut-over date ) is not part of the template, as posting date will be maintained by the Syensqo data team in the view FINSV_MIG_CTRL_1. This posting date will be used across all the financial transactions migrations ( exception is Trial Balance ).
However, because the migration is performed periodically, the posting date must be updated for each period, which can be very time-consuming. To streamline the process, it would be advisable to enhance the migration cockpit object to include the posting date directly within the upload template.

Legal/Group Currency Calculation
During the migration of GL balances from SAP ECC to S/4HANA, it was identified that group currency balances are missing. To address this, the plan is to derive group currency amounts by reading the relevant exchange rates from the BFC consolidation system for each period within the migration scope.
For each period:
This approach ensures consistency between the group currency balances in S/4HANA and the consolidation system.
| Period (YYYYMM) | Local Currency | Legal Currency | Exchange Rate (Local to Legal - Currency Type 30) | Group Currency | Exchange Rate (Local to Group - Currency Type 31) | Source System (e.g., BFC) |
|---|---|---|---|---|---|---|
| 202401 | EUR | USD | 1.10 | USD | 1.10 | BFC |
| 202402 | EUR | USD | 1.12 | USD | 1.12 | BFC |
| 202401 | GBP | USD | 1.30 | USD | 1.30 | BFC |
| 202402 | GBP | USD | 1.28 | USD | 1.28 | BFC |
| 202401 | CNY | USD | 0.14 | USD | 0.14 | BFC |
| . | . | . | . | . | . | . |
| 202402 | CNY | USD | 0.15 | USD | 0.15 | BFC |
Currency Adjustment During Migration (TCURX Consideration)
In SAP, the TCURX table defines the number of decimal places used for each currency.
This impacts how amounts are stored internally in database tables versus how they are displayed externally in user interfaces or reports.
Currencies such as JPY (Japanese Yen), KRW (Korean Won), or VND (Vietnamese Dong) are typically configured with no decimal places (TCURX-CURRDEC = 0).
Understanding and correctly applying the TCURX rules is essential during data migration to ensure financial consistency between ECC and S/4HANA.
| External Amount | The amount value as displayed to users in SAP screens and reports. | 96015 JPY | |
| Internal Amount | The amount value stored in database tables for computation. | 960.15 | Multiplied by factor = 10² if target has 2 decimals |
During data migration, these internal (technical) amounts must be converted to external amounts to ensure accuracy and consistency in the target S/4HANA system.
Conversion Formula:
External Amount = Internal Amount * 10 to the power ( 2 - Number of decimal for the currency in TCURX table )
How to derive profit centres for various GL balance components:
For each reporting period, balance sheet balances should ideally be allocated to the appropriate profit centres for all the accounts including balance sheet accounts. However, given the complexity involved, a more practical approach is outlined below for the balance sheet accounts.
Cutover Period:
During the cutover period, balances related to sub-ledger control accounts will already be correctly assigned to the respective profit centres from the sub-ledger side. therefore, For the cutover period, general ledger migration balances must be distributed by profit centre in accordance with the details outlined below. This ensures that the sub-ledger take-on account balances recorded in the general ledger can be properly offset against the sub-ledger clearing entries.
Prior Periods ( Including Opening balance):
For periods preceding the cutover, sub-ledger control account balances will be derived from the general ledger and migrated into the respective sub-ledger take-on accounts. However, these ledger-based balances do not contain profit centre details. As the balances for each period will later be reversed, unless a viable solution and compelling business case exist to justify detailed allocation given the significant complexity involved, the balances for periods prior to the cutover may be migrated using a default profit centre.
Note: A default Profit Center will be maintained for each company code in ADMM and will be applied in cases where Profit Center derivation is not possible due to unavailable data.
