SAP BLOG SAP Central Finance – !!! Plan your CUTOVER !!!

This blog focusses on the cutover activities of the SAP Central Finance project. Before we reach this stage it is assumed that the test activities are complete, business sign off is received to starting with the production cutover activities.

We will not explain what cutover is and what is the relevance of this activity in this blog as you must have done the cutover several times in any ERP implementation.

When Central Finance project goes live we need to ensure that below activities are being taken care in sequence and also its assumed that you have already tested data replication from source production system to SAP Central Finance Non-Production system. If this is the case then the activity of deleting staging table is also very important and critical. Let see the core activities by stream. Its a joint effort and not just one team can make it happen



Infrastructure Area

• Source Production system is ready with all relevant SAP notes including those which are identified during testing
• Capacity Check of source production system is complete
• Productive SLT system is running
• SAP S/4HANA production system is ready from connectivity standpoint – RFC, SLT, SLD
• All SAP S/4HANA Functional & Technical Transports are moved to Productive system (via solution manager or manual or some other tool) and those are validated by the functional team
• Other key activities include
  • AIF Configurations
  • AIF number ranges
  • User access for AIF in AIF Recipients
  • Creation & maintenance of logical systems

Security & authorisations Area

• All users have necessary access to the SAP Production system
• All fiori related access are provided
• All RFC users have right authorisations
• Any custom roles needed are built and tested

Functional & Technical

• Validation of Configuration data
• Manual activities on top of configuration like number ranges, custom tables or any other such activity
• Open Posting periods
• OKB9 settings if needed at all
• Exchange rate maintenance
• CO documents number ranges using KANK
• Substitution accounts for Reconciliation & open items
• Clearing accounts

Data

Master Data load including but not limited to

• GL Accounts
• Cost Centers
• Profit Centers
• Cost Elements
• Business Partners
• Materials

• Mappings of all relevant objects either using FINS_CFIN_MAP_MANAGE or any custom entity
• Master Data replication should be planned as Central Finance assumes that master data replication from source system is up & running before you start transaction data replication
• Mapping test & simulation
• Any other data related activity

Functional

• Smoke test for Internal Order replication
• Smoke test for CO documents
• Validation of data in CFIN system for which smoke test is done

Now we will start with the Initial Load activities which are mostly functional in collaboration with Basis & security along with data team.

Before we do this we need to ensure that on source system the month end activities are complete, period is closed to ensure we don’t miss anything.

• Extraction of Finance Data
• Complete CO Initial Load preparation activities
• Complete AUFK (Internal Order) data load using SLT
• Resolve AIF errors for Internal Order Data
• Run simulation postings for Finance
• Resolve all errors in FI postings (these don’t go to AIF rather different window)
• Validation Data via standard reconciliation reports
• Validate data using custom reports (if any)
• Execute CO Initial load via SLT
• Resolve AIF errors in CO Data
• Reconcile CO data using standard reports
• Mark Initial load as complete in VCFIN_SOURCE_SET for the company code related to
• Monitor AIF for replication
• Fix errors

And you are live now.

Please note – This is the list of basic & standard activities which you have to do in any program. On top of this any relevant custom solution needs to be be considered which might ask for any additional activity at different point in time depending on the relevance and alignment of data.

Some key transactions you will need during this process are below however you can directly access them using SPRO or CFINIMG
