SAP BLOG ECC to S/4 HANA – Finance Conversion

This blog will detail the important points to consider for a conversion.

As a first step we need to determine the business processes that will be impacted when making the conversion to S / 4. For that you need to check the simplification list Simplification



As approach it is important to know the following points:

• Business Partner Approach (Customer/Vendor integration) mandatory in S/4HANA

• The FI-AR-CR Credit Management has been replaced by SAP Credit Management (FIN-FSCM-CR)

• Material Ledger mandatory for material valuation

• Classic Cash Management has been replaced by new SAP Cash Management.

• New Asset Accounting Required

• Classic Real Estate has been replaced by New Real Estate

• Fiori 2.0 required if Fiori is used in 1709

• Traditional Foreign Trade functionality in SD/MM replaced by Global Trade Server

• Revenue Recognition in SD (SD-RR) has been replaced by free of charge add on Revenue Accounting and Reporting

Now it is necessary to understand that: S/4HANA Conversion is not a technical upgrade only. It includes functional changes. This must be considered appropriately in the project plan.



And now talking about Finance Conversion you need know:

• SAP conversion programs read data from old tables and transfer them to new structures.
• Compatibility views (tables) are created to make old reports / transaction codes work.
• Configuration/customizing has to be adapted in some areas (see Simplification List).
• For Finance the customizing has to be done during Conversion. It cannot be prepared in the old system.

• With a system Conversion it is not possible to activate new functionalities like document split, parallel ledgers etc. Classic general ledger is transferred technically to new general ledger/ACDOCA without activating new functionalitie

The tasks to be performed in the source system before conversion are the following:

• Identify and review the relevant Simplification items
• Prepare Asset Accounting and Material Ledger
• Run Customizing pre-checks and adapt settings, if needed
• Check consistency and reconcile data
• Period end closing activities
• Document your posting data
• Archive data no longer need

Preparing Application Specific Tasks









Finally at the time of making the conversion it is important to know 2 things:



1- During the migration of information, errors of information inconsistencies can be detected:

• Inconsistencies caused by hardware defect (e.g. corrupt blocks)
• Inconsistencies caused by user handling errors (e.g. switching off line item display in FI
• without line item deletion, missing balance carry forward, etc.)
• Customer reports without consistent updates on the database
• Manipulation on the database (e.g. direct postings on reconciliation accounts)
• Improper customizing changes (without respecting warning messages)
• Wrong migration (from former migrations)
• Wrong data management strategy (e.g. deletion of wrong data, archiving of FI data of the current fiscal year)

2- Recon Reports (to be run before and after conversion)

• The financial statements (program RFBILA00)
• The asset history sheet (program RAGITT_ALV01)
• The depreciation run for the planned depreciations (program RAHAFA_ALV01)
• The totals report for cost centers (transaction S_ALR_87013611)
• Sales order selection (program RKKBSELL)
• The G/L account balance list (program RFSSLD00)
• The general ledger line items list (program RFSOPO00)
• The compact document journal (program RFBELJ00)
• The vendor sales (program RFKUML00)
• The vendor open item list (program RFKEPL00)
• The customer sales (program RFKUML00)
• The customer open item list (program RFDEPL00)
• The customer recurring entry original documents (program RFDAUB00)
• The cost centers: actual/plan/variance (transaction GR55 with report group 1SIP)
