Steps to remember for the Conversion:

Preparation of Data

Before starting system conversion, get system ready by performing the following activities:

⇒ Check the consistency of your financial data and perform reconciliation between your accounting components, so the data can be merged correctly in the universal journal entry. In SAP S/4HANA all line item documents are stored in the universal ACDOCA data table.

⇒ Perform period-end closing including the storage of reporting key figures and closing the posting periods.

  • Lock the current and previous periods in Materials Management using program RMMMPERI.
  • Perform closing for periodic asset postings using program RAPERB2000.
  • Execute the periodic depreciation posting run using program RAPOST2000.
  • Make sure that all held documents have either been posted or deleted.
  • If you are already using account-based profitability analysis, perform a delta upload to SAP BW for all account-based CO-PA DataSources for which you use the delta method.

⇒ Document the posting data. Make sure that all carry forward balances are complete and consistent. To ensure this, carry forward the balances for all currencies and all ledgers.

⇒ Archive any data that you no longer need in every day business processes before the migration.

⇒ If you have not been using the new depreciation calculation from the Enterprise Extension Financials Extension (EA-FIN) you must implement it as part of a separate project.

Prepare Asset Accounting

Activate the new depreciation calculation in your source system. To do so you must activate the EA-FIN business function.

Perform Pre-Checks

 ⇒ Pre-Checks help you identify the steps you need to take to ensure your system is compatible with the conversion process.

⇒ The Controlling and General Ledger pre-checks provided analyze whether your ledger, company code and controlling area settings are consistent and can be migrated to SAP S/4HANA. These Controlling and General Ledger pre-checks are automatically executed when you run the report R_S4_PRE_TRANSITION_CHECKS.

⇒ To run pre-checks for Asset Accounting (FI-AA), please implement the SAP Notes listed in the collective SAP Note 2333236. The pre-check program for Asset Accounting (FI-AA) is not included in the central pre-check report R_S4_PRE_TRANSITION_CHECKS. To execute the appropriate pre-checks for Asset Accounting, please run the report RASFIN_MIGR_PRECHECK.

⇒ Whereas you run the report R_S4_PRE_TRANSITION_CHECKS in client 000 to perform the checks across all clients, then run the report RASFIN_MIGR_PRECHECK in each productive client.
