Purpose

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.

Conversion Scope

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

Primary transactions refer to original postings from all sources whether it is debit or credit.
Secondary transactions refer to allocations from sources such as allocations from payroll, work orders, other WBS Elements or cost centers. These postings will be subject to any settlement rules set up in the individual WBS Element.

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:

Z1100 Intangible-AUC
Z1101 Intangible-R&I under construction
Z1300 Tangible-AUC

List of source systems and approximate number of records

Source	Scope	Source Approx No. of Records	Target System	Target Approx No. of Records
Legacy systems	Project level exclusions based on following relevancy rules: All projects with an out-of-scope company code will not be migrated. All closed projects as at the end of the previous fiscal year will not be migrated. All projects marked for deletion as at the end of the previous fiscal year will not be migrated. All projects without relevant WBS elements will not be migrated. Projects marked as statistical will not be migrated.		S/4HANA
Legacy systems	Any WBS element that is not closed as at the end of the previous fiscal year will be migrated. After eliminating all closed WBS elements, the relevancy rule will look for any WBS element that is not marked for deletion as at the end of the previous fiscal year for migration. Exceptions: Any closed WBS element that exists within an open Project. Any WBS element that is marked for deletion that exists in an open Project. Any closed WBS element that is affected by an open Projects.
DCT	Where legal entities do not use SAP to record their projects, the DCT will be used to collect the WBS element data. This will be used in conjunction with the PPM Item DCT to collect Projects that are not in legacy systems. There will be a creation of one WBS element to one Project Definition.	TBC	S/4HANA	TBC

Target Design

There are two types of costs in the WBS Elements:

Costs that are sourced from primary and secondary cost elements.
The secondary cost elements cannot be used to post costs to S/4HANA. In many cases, the secondary cost element will form part of the total for the WBS Element. These costs (Table COSS) must be considered but the use of a primary cost element will be used to post these costs to the WBS Element in S/4 HANA. The Primary Cost Total (COSP) table in source system (PF2 and WP2) also shows the values that have been settled to the receiver, be it an Asset Under Construction or a Cost Centre or a General Ledger Account.

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.

The technical design of the target for this conversion approach.

Extraction

Extract data from a source into . There are 2 possibilities:

The data exists. connects to the source and loads the data into . There are 3 methods:
1. Perform full data extraction from relevant tables in the source system(s).
2. Perform extraction through the application layer.
3. Only if ; cannot connect to the source, data is loaded to the repository from the provided source system extract/report.
The data does not exist (or cannot be converted from its current state). The data is manually collected by the business directly in . This is to be conducted using DCT (Data Collection Template) in

The agreed Relevancy criteria is applied to the extracted records to identify the records that are applicable for the Target loads

Extraction Run Sheet

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:

Primary Cost Total (COSP) table
Secondary Cost Total (COSS) table

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)

Field	Value
Object Numbers	For each relevant WBS Element extract the object number from source system from table PRPS. Enter the extracted number in the field of this table.

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.

Field	Value
Object Numbers	Enter the same Object Numbers as the above steps for Primary Costs (Table COSP) and Secondary Costs (Table COSS).

System will provide a report as below that will include the following fields:

Field	Example
Object Numbers	PR********
Account Assignment Category	Will return one of the following Fixed Asset Cost Centre GL Account
Company Code	Company code where the transaction was posted
G/L Account	If the Account Assignment is SK, an entry will appear in this field
Cost Centre	If the Account Assignment is KS, an entry will appear in this field
Asset	If the Account Assignment is AN, an entry will appear in this field. This will possibly show both (the Final asset and the AUC) if any values have been posted to the final asset.

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).

Field	Description	Value
ANEP-BUKRS	Company Code	Company code from the above step.
ANEP-ANLN1	Asset Number	Asset numbers from the above step.
ANEP-GJAHR	Fiscal Year	1900 up to the FY of the last month before go-live date

System will generate as below:

Field	Description	Value
ANEP-BUKRS	Company Code	Company code from the above step.
ANEP-ANLN1	Asset Number	Asset numbers from the above step.
ANEP-GJAHR	Fiscal Year	Fiscal year posting for each year
ANEP-AFABE	Depreciation Area	01
ANEP-BWASL	Transaction Type	Transaction types that are used for posting
ANEP-ANBTR	Amount Posted	Amount posted

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.

Check

Action

Balance remains in AUC where the value in the AUC equals with the value in the WBS.

Postings must be made to the WBS and settle to the AUC.

Balance remains in the AUC but the value in the AUC does not equal the total postings in the WBS.

Postings must be made to the WBS and the AUC but only up to the value in the AUC. Investigate why the postings are different. This is due mainly to partial settlement to a fixed asset based on Transaction Types 338 (Retirement transfer of PY acquisition from investment measure) and 339 (Acquiring transfer of CY acquisition from investment measure).

No balance in the AUC

No requirement to post any postings to the WBS Element or the AUC. The probable reason is that the AUC has been fully settled to a fixed asset.

Post statistical posting the same amount as fixed asset amount.

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)

The following pre-load validations will be performed by the Business.

Completeness

Task	Action
Verify counts	Business to verify the load count is the same as per identified data from WBS Elements relevancy. The report will be the same one used by the Data Team ready for upload.

Accuracy

Task	Action
Validate	Business to verify that all the data in the load table/file is accurate as per the endorsed transformation rules and mapping. It needs to be 100% accurate.

Load

To load Project Definition:

See the DCT for PPM Item Load Section. All these relevant Project Definitions will be loaded into the PPM modules as PPM Items. Within SAP there is a special upload file and upload program that will load these Project Definitions into PPM Items.

Once these Project Definitions are loaded into PPM Items there will be a trigger to use the Project Definition Template to post these PPM Items as Project Definitions together with the first two levels of WBS Elements in S/4HANA SAP Project Systems.

Then we will use the BAPI below to map the legacy WBS Elements to the correct level two WBS Element. The assumption here is that by cutover all WBS Elements will be created in the following manner thus making it easier to map to the correct WBS Element.

The load process includes:

Execute the automated data load into target system using load tool or product the load file if the load must be done manually
Once the data is loaded to the target system, it will be extracted and prepared for Post Load Data Validation
