What is New:

To simplify the migration process, as of SAP S/4HANA 1909, following manual steps are included in Central Migration Cockpit (Start and Monitor Data Migration)

• Activities "Fill in Due Dates in FI Document and Display Status of Filling Due Dates into FI Documents are now executed automatically in the Enrich Transactional Data (ENR) step of the Start and Monitor Data Migration activity.

 

• Migrate House Bank Accounts now executed automatically in the Migrate House Bank Account (T012K) to Bank Account (CM1) step of the Start and Monitor Data Migration Activity

 

• Migrate General Ledger Allocations activity now executed automatically in the Migration of the GL Allocations (GL)AL_MIG) step of the Start and Monitor Data Migration activity.

High -level SAP S/4HANA Data Model Changes relating to House Banks:

House Banks in SAP S/4HANA:

1. House bank accounts merged into bank account master data. As a part of migration,  house bank accounts originally stored in database table T012K moves to table FCLM_BAM_ACLINK2.


2. After Migration, we can create the House banks using transaction code FI12_HBANK. This transaction code is only for creating the House bank but not Bank Accounts for House Banks.


3. Activation of Business Function FIN_FSCM_CLM is not mandatory for Migration of House Banks. (Not full scope of CLM used)


4. Some House Bank Related table names

Table Name	Description
FCLM_BAM_AC_LINK	Linkages Between House Bank Accounts and Bank Accounts
FCLM_BAM_AC_TYPE	Bank Account Type
FCLM_BAM_AC_TYPT	Bank Account Type Text
FCLM_BAM_ACLINK2	Linkages Between Bank Account and House Bank Accounts
FCLM_BAM_AMD	Bank Account Master Data

FCLM_BAM_BKBPHIS	History for Bank and BP Linkage
FCLM_BAM_BNKABP2	Relationship between Bank and Business Partner
FCLM_BAM_CONFIG	Configuration for Bank Account Management
FCLM_BAM_HIER	Bank Account Hierarchy

House bank Migration

House Bank Migration is a part of Migration Cockpit. (IMG>Conversion of Accounting to SAP S/4HANA>Data Migration>Start and Monitor Data Migration.

All the pre-conversion requisites to be completed.

All pre-requisites for executing the Migration Cockpit is completed.

As a part of Migration Cockpit execution, House Bank also gets migrated.

If the errors are relating to pre-delivered content, we can also accept the errors, if we are convinced about the nature of those errors. If it is relating to the Business bank data information, further analysis and fix is required.

Based on the errors during Migration Cockpit execution, we can fix the errors whatever is possible, reset and reexecute the step in Migration Cockpit.

If any errors found during the migration cockpit run, we can also execute the house bank migration manually using Tcode: FCLM_BAM_MIGRATION. This tcode gives an opportunity to see the status traffic light. We can re-execute for the red ones to know any further errors.

After executing the migration, we can also see log in tcode: SLG1 to see the details of the error.

Most of the errors during House bank migration are self explanatory.

SAP Notes, given under references section gives a good idea about House Banks related topics.

Please note, we need to document the process steps followed for resolution of the House bank migration issues and thorough testing is done subsequent to migration. This helps to have a clarity  during the next/subsequent cycle runs before the Production run of migration.

How to Access House bank Accounts, after Migration.

House Bank Accounts can be accessed either by Fiori Apps or through NWBC.

We can find the fiori apps in the fiori apps library https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/home

During the initial phase of Conversion/Migration cycles - fiori set up may not be ready, possibly!

This is required only to see the house bank after migration or to set up new house bank accounts for testing.
