Conversion of Accounting to SAP S/4HANA

Migration Preparation

After fulfilling the System Prerequisites for the Migration we can start with the Migration Preparation:

Details – Analysis and Preparation of Migration

Items to Check Before Migration:

  • Pre-Check for the new asset accounting
  • SI-Check and SAP Readiness Check 
  • Check SAP Notes (2214409 and 2011192)
  • Check industry solutions
  • Custom Code analyzer for simplification list (Custom Code Migration Tool)
  • Maintenance planner must be used; it checks if add-ons, business functions, and industry solutions are supported for the conversion

Preparing for Migration:

  • Creating business partner by customer vendor integration
  • Sizing (SAP Notes 1872170 and 1793345)
  • Corrections and reporting

Preparation Phase Asset Accounting:

  • Close all fiscal years except the current fiscal year 
  • Check SAP Note 965032
  • Perform period-end closing activities

Preparation Phase Asset Accounting: Additional Currency

For every additional currency type defined on the company code, a corresponding depreciation area needs to be set up. Your current system configuration might not match this new requirement.

Preparation Phase Asset Accounting: EA-FIN Financials Extensions

EA-FIN is required for FI-AA (new) and SAP S/4HANA. The business function should be activated and tested in a small separate project before the migration.

Preparation Phase Reconciliation

  • Use RFINDEX_NACC for FI Consistency Check
  • Reconcile asset accounting with GL (TA ABST and ABST2)
  • Reconcile AP/AR sub ledger with GL (Report TFC_COMPARE_VZ)
  • Reconcile materials management with GL (reports RM07MBST & RM07MMFI)
  • Check FI documents with FI balances (TA F.03)

In one of the next Newsletter we will describe the Reports for the Before-After Comparison and the Preparing for Business Partner Adoption.
