The purpose of this document is to define the conversion approach to migrate the balance of Capex WBS from legacy system to S/4HANA.
All the financial transactions posted of all open WBS Elements as at 30 June 2028 (for Go live 1 July 2028) and as at 31 Dec 2028 (for Go live 1 Jan 2029) in the source systems (PF2 and WP2). All these transactions will be totaled into the one single value and then be posted to the relevant WBS Elements in S/4HANA. The approach will also run SAP settlement to the relevant Asset Under Construction.
The scope of this document covers the approach for converting active Capex WBS element from Legacy Source Systems into S/4HANA.
All the relevant WBS Elements (after applying the approved relevancy rules) open as at end of last month before go live that have received primary and secondary transactions posted to the cost elements within the WBS Elements
The scope of this document will therefore extract the settlement transactions from each individual WBS Element to provide a base for posting to the S/4HANA WBS Elements as at end of last month before go live. The total of the transactions will be used to compare to the balance in the Asset Under Construction that is used for settlement. The total of the settlement transactions will also be reconciled against the total costs posted to the WBS Element to ensure that all costs have been captured. Therefore, the scope will extend to the reconciliation of the legacy Asset Under Construction values
Below are the list of AUC classes for SyWay:
The data from legacy system includes:
The data from legacy system excludes:
There will be 3 SAP boxes:
a. CUI box (US, GB, DE)
b. China box
c. ROW (Rest of the World) box
Please refer to file "Entreprise Structure Catalog" to see which company codes fall under which SAP boxes.
In terms of data migration, below is the guideline:
- Non CUI objects : Migration to US system by Syniti
- CUI objects : Manual cleansing/separate migration cockpit (Syniti is not certified)

Specify any special requirements or considerations that may impact the data conversion process based on specific locations, regulatory compliance or system limitations. Clearly outline any regional or localization requirements such as country-specific data formats, legal reporting obligations or industry standards that must be adhered to (e.g., localization rules for countries like China).
If the data conversion involves third-party systems or external data sources, such as Icertis, describe any additional requirements related to data mapping, transformation logic, validation rules or security measures that must be followed.
There are two types of costs in the WBS Elements:
There is no need to replicate the postings that have occurred in the source system. The value that has been settled to the receiver object can be used to post with a selected General Ledger account. The settlement can then also use this account to clear the balance at the level. The offset General Ledger account will still be used to balance the journal entries.

Extract data from a source into Syniti Migrate. There are 2 possibilities:
The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads
| Req # | Requirement Description | Team Responsible | ||||||||||||||||||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1. | Extract data from source systems based on the current relevancy rules that apply to the Project and WBS Element Master Data. For each relevant WBS Element extract the object number from source systems with WBS Elements from table PRPS. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 2. | The following tables will be used to extract the settlement data:
To ensure that all costs have been collected via these tables (COSP & COSS), run a report (transaction code CJI3) to extract all the costs posted to the WBS Element/s to reconcile against the totals extracted from table COSP & COSS. Compare and agree the reconciliation values before progressing further to the next steps. For each open Project, confirm that the final balance is zero which will ensure that the settlement costs represent all the postings (debit and credit) within the Project by WBS Element. Extract the transactions by business transaction type. Use table AUFK to reconcile the settlement costs against actual posting extracts (extract by year by period by settlement transaction for each Project. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 3. | Go to source systems (PF2 and WP2) Primary Costs Total (Table COSP)
Go to source system (PF2 and WP2) Secondary Costs Total (Table COSS)
From the above, system will generate report as below. The report will need to be summarized by object number by total for all the fiscal years.
| Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 4. | Step #3 provides what needs to be posted for each WBS Element. These can be split across cost elements, but the proposal is to use one Cost Element for both posting and settlement (GL account TBD) | Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 5. | Extract the Settlement Rule object from table COBRB in source systems (PF2 and WP2) to find the settlement objects for the above project.
System will provide a report as below that will include the following fields:
Extract the asset numbers from this report. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 6. | Extract the fixed asset values from table ANEP in source systems (PF2 and WP2) to check what has been posted to the Asset under Construction (AUC).
System will generate as below:
This report will need to be summarized by Object Number by total for all months. Check against the WBS Element postings before loading into S/4HANA.
| Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 7. | Run transaction code S_ALR_87011963 (Asset Balances report) for all AUC assets within the relevant Company Code. Check each individual asset balance before making any posting to a WBS Element. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||
| 8. | Once the overall balance has been agreed above, posting will be required and run settlement (CJ8G) | Data Team |

A DCT will be required to collect the transactions posted to the WBS Elements/Project that are not in PF2 and WP2 but have been selected in the DCT for master data for Projects and WBS Elements – CAPEX.
Target Ready Data Collection Template will be created for Data Object data with exception of some fields which require transformation as mentioned in the transformation rule.

After validating the WBS Element transaction movements for count and accuracy, run settlement. This will provide balances to the AUCs.
AUC master will be created automatically once the WBS status is changed from CRTD (Created) to REL (Released) status.
Transaction code CJ88 will be used to settle all the WBS Element costs to their respective settlement objects. For those that are settling to the AUCs, a reconciliation must be done to compare the AUCs in the legacy system to those that are now in S/4HANA. Table ANLC will be used for this comparison.
The FA previous fiscal year cannot be closed until the AUC reconciliation for the previous year is completed.

2. | Identify all assets under the AUC Asset ClassesApply the results from the above table to identify all assets in legacy systems in table ANLA that are classified as Assets Under Construction. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3. | Identify all the above Assets Under Construction that have a previous year balance.The AUC may be restricted to only the ones with balances. Use table ANLC to gather year end balances. When running the report in Table ANLC it must run by Company Code by selected asset number. If it is run by asset number alone, all assets from across all regions will be selected. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4. | Identify all the above Assets Under Construction that have a current year balance.Reconcile the results from the above report to identify any new AUC’s that may have been created in the current year. | Data Team | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
