Migration from Classic to New Asset Accounting

 

Prepare New Asset Accounting

​

The following activities are relevant for you if you have been using classic Asset Accounting up to now and you now want to migrate to new Asset Accounting.

These and the following activities support you in migrating Customizing data; once you have completed these activities, you can activate new Asset Accounting. Migrating transaction data is not possible until after that; however, the migration of transaction data is not a part of these IMG activities. The documents from Asset Accounting are migrated as part of the migration of documents from the general ledger. You must then build the depreciation values of your fixed assets as initial.

 

Overview of Steps

​

To be able to use new Asset Accounting, you have to follow the steps below (among others).

The steps differ depending on whether you are in the Customizing system or in Test system/Production system.

 

Steps in the Customizing system:

1. Create prerequisites for the use of new Asset Accounting
2. Install SAP S/4HANA with new Asset Accounting
3. Follow the relevant steps for migrating to new General Ledger Accounting
4. Migrate the charts of depreciation for new Asset Accounting. Current activity and following activity; see the "Activities" section below.
5. Make additional manual settings in Customizing for new Asset Accounting (Customizing activity Perform Additional Manual Activities)
6. Check the prerequisites for activating new Asset Accounting (Customizing activity Check Prerequisites for Activating Asset Accounting New)
7. Activate the Customizing switch Customizing activity Activate New Asset Accounting 

 

Steps in the Test system and Production system (Downstream system):

   

8. Create prerequisites for the use of new Asset Accounting
9. Lock the test system and production system to posting
10. Install SAP S/4HANA with new Asset Accounting
11. Follow the relevant steps for migrating to new General Ledger Accounting
12. Create necessary master data (See step 5 for the Customizing system)
13. Import the new Customizing settings into your production system
14. Check in the production system whether the transport successfully imported the activated Customizing switch
15. Unlock the production system for postings

​

Warning:

• When you install SAP S/4HANA, the system shows the new IMG structure Asset Accounting in the SAP Reference IMG, which also contains this activity. At the same time, the system hides the IMG structure for classic Asset Accounting

• Immediately after you have installed SAP S/4HANA (step 2 in the Customizing system or step 10 in the test and production system), posting is no longer possible in Asset Accounting - neither using the old logic nor the new logic. You cannot post using the new logic until after the migration of your Customizing data and transaction data (documents)

• After you have performed the migration and activated new Asset Accounting, it is not possible to return to using classic Asset Accounting. Classic Asset Accounting does not exist in SAP S/4HANA

 

Requirements

   Steps 1 and 8: Create prerequisites for the use of new Asset Accounting

   (Number sequence for the steps: See above.)

   Before you install SAP S/4HANA, you have to ensure that the
   prerequisites are met. You can do so using the program for preliminary
   checks RASFIN_MIGR_PRECHECK. You import this program to your system by
   means of SAP Note 1939592 before you install SAP S/4HANA. Perform this
   check in all of your systems - in the Customizing system as well as in
   the test system and production system.

   Prerequisites for the use of new Asset Accounting

   Non-Compatible Components

   If you migrate to SAP S/4HANA and want to use new Asset Accounting, you
   are not allowed to use any of the following components:

   o   From the Financials Extension (EA-FIN):
       Lease Accounting Engine (LAE)
       The LAE controls postings for the lessor scenario; this scenario
       consists of the components CRM Leasing (CRM-LAM) and Leasing
       Accounting (FI-LA).

   o   Real Estate (RE), that is, classic Real Estate Management

   o   From Funds Management (PSM-FM) or Industry-Specific Component Public
       Sector (IS-PS):
       Requests with Reference to Asset

   Detailed Prerequisites

   o   You have activated the Financials Extension (EA-FIN) business
       function, since you need the new depreciation calculation with the
       Depreciation Calculation Program (DCP) from EA-FIN. Either you
       Depreciation Calculation Program (DCP) from EA-FIN. Either you
       already activated EA-FIN in any case at an earlier point in time, or
       you activate EA-FIN manually in your systems as part of a project,
       before you install SAP S/4HANA.

   o   To map parallel accounting, you use either the ledger approach in
       new General Ledger Accounting or the accounts approach in classic
       General Ledger Accounting.

   o   The following applies for Asset Accounting:

       -   You have configured the classic Asset Accounting (FI-AA)
           application component.

       -   Or: If you have not previously used classic Asset Accounting,
           you need to make all of the necessary Customizing settings for
           new Asset Accounting.

   o   Check whether you can completely archive documents from deactivated
       company codes (this means company codes that only allow subsequent
       reporting).
       If you do not archive the documents of the company code, you must do
       the following:

       -   You must migrate the assigned chart of depreciation; and

       -   You must migrate the documents with the document migration.

   o   The parallel currencies in the leading ledger in General Ledger
       Accounting and in the depreciation areas of the leading valuation in
       Asset Accounting must be the same.
       For the ledger approach, you also have to take the following into
       account: Company codes that are assigned to the same chart of
       depreciation are not allowed to be different in number and type to
       the parallel currencies used in General Ledger Accounting. This
       means, the parallel valuations of the non-leading ledger and the
       depreciation areas of the parallel valuation in Asset Accounting
       have to be congruent.
       If you have previously been using parallel currencies in General
       Ledger Accounting, but you have not implemented the corresponding
       parallel currency areas in Asset Accounting for all depreciation
        areas, you must first implement these depreciation areas before you
        install SAP S/4HANA. Contact your consultant.

    o   Note that company codes that are assigned to the same chart of
        depreciation are not allowed to be different in number and type to
        the parallel currencies used in General Ledger Accounting.

    Preparation

    If, up to now, you were using classic Asset Accounting with classic
    General Ledger Accounting or classic Asset Accounting with new General
    Ledger Accounting, you have to make the following preparations:

    o   Make sure that period-end closing was performed (the following
        programs (among others): RAPOST2000, RAPERB2000, reconciliation of
        the asset subsidiary ledger with the general ledger (account balance
        list and asset list, RAABST01, RAABST02).
        If you install SAP S/4HANA at the close of the fiscal year, you
        should also perform year-end closing. The year-end closing must be
        executed across components (so, for Asset Accounting and General
        Ledger Accounting), whereby the year-end closing in the components
        must be synchronized (so affecting the same fiscal year).
        The migration must definitely take place at a time when only one
        fiscal year is open in Asset Accounting.
        Note: If you have already performed a balance carryforward to future
        years for Asset Accounting, a migration is not possible. If this is
        the case, contact SAP.

    o   Lock the users to ensure that no additional postings are made.

    o   Make sure that the periodic asset postings (with program RAPERB2000)
        are completed.

    o   Also ensure that there are no update terminations from direct
        postings in the system.

 

    Caution:
    You can no longer post once you have installed SAP S/4HANA. Posting is
   only possible again after you have completed the migration fully and
   successfully. For the installation and the migration to be successful,
   it is mandatory that you ensure the completeness of the postings for the
   period-end closing before the installation.

   When to install SAP S/4HANA with new Asset Accounting.

   From the point of view of Asset Accounting, you can install SAP S/4HANA
   at any time; however, it is a requirement that a period-end closing must
   have been completed.

   You need to have fully completed all periodic and current posting
   processes that involve Asset Accounting. You must not make any postings
   during the changeover.

   Caution:
   You are only allowed to perform the next steps once you have made sure
   that your system meets the prerequisites for installing SAP S/4HANA by
   using the program mentioned above for preliminary checks,
   RASFIN_MIGR_PRECHECK.

 

   Activities

   Steps 2 and 10: Install SAP S/4HANA with new Asset Accounting.

   You start the installation of SAP S/4HANA. Starting from this point in
   time, it is no longer possible to post in Asset Accounting.

   If you were already using classic Asset Accounting, then you only have
   to migrate your charts of depreciation, and check and possibly add to
   delta Customizing.

   If you were not already using Asset Accounting and now want to use it in
   the future, you have to completely configure your system for Asset
   Accounting. The following does not explain the individual steps
   necessary for this configuration. In the case of a complete
   configuration, you have to perform step 7 after the configuration is
   complete, and activate the Customizing switch (Activate New Asset
Accounting activity).

 Steps 3 and 11: Follow the relevant steps for migrating to new General
Ledger Accounting

 SAP S/4HANA is based on new General Ledger Accounting (FI-GL). If you
want to use SAP S/4HANA, but were still using classic General Ledger
Accounting until now, the data for General Ledger Accounting is migrated
during the migration.

 Step 4: Migrate the charts of depreciation for new Asset Accounting.

 This step is necessary if you have been using classic Asset Accounting.

 You can either migrate the charts of depreciation automatically using
the migration program, or manually.

 I. Check/create accounting principles

 Check if there are accounting principles in the system for your leading
and parallel valuations. If not, then create them.

 You check and change Customizing for accounting principles in

 Customizing under Financial Accounting -> Financial Accounting Global
Settings -> Ledgers -> Parallel Accounting -> Define Accounting
Principles.

 II. Check ledgers and ledger groups

 The following applies to the ledger approach: One ledger with a ledger
group has to exist in the system for each valuation, so for the leading
valuation and the parallel valuation. This is normally ledger 0L for the
leading ledger with ledger group 0L.

 The following applies for the accounts approach: The leading ledger with
the ledger group has to have been created in the system. This represents
your leading valuation. For each parallel valuation, you have to create
a (new) ledger group that also contains the leading ledger as a
representative ledger.
The leading ledger 0L with ledger group 0L is usually created by default
in the system.

 Check if the necessary ledgers and ledger groups have been created in
the system.

 You change Customizing for ledgers in Customizing under Financial
Accounting -> Financial Accounting Global Settings -> Ledgers -> Define
Ledgers for General Ledger Accounting.

 You change Customizing for ledger groups in Customizing under Financial
Accounting -> Financial Accounting Global Settings -> Ledgers -> Define
Ledger Group.

 For the accounts approach, you can also have the option of having the
system generate the ledger group for parallel valuation. Start the
migration program (see below). The migration cannot completely take
place due to the missing ledger group for parallel valuation and the
missing assignment of this ledger group to an accounting principle.
However, the system generates a ledger group for each valuation. Its
name is made up of <& number of the leading depreciation area of the
parallel valuation &>.

 Adjust the name of the generated ledger group, if necessary. Run the
migration program again later. (See the "Migrate Charts of Accounts"
section below.)

 III. Assign accounting principles to ledger groups

 You change the assignment in Customizing under Financial Accounting ->
Financial Accounting Global Settings -> Ledgers -> ->Parallel Accounting
-> Assign Accounting Principle to Ledger Groups.

 Assign the accounting principle to the ledger group for each valuation
that is represented by a depreciation area in your chart of
depreciation.

 IV. Check assignment of accounting principle for ledger/company code.

 Check the assignment of the accounting principle for the combination of   
   ledger and company code in Customizing under Define Settings for Ledger
   and Currency Types.

   V. Migrate Charts of Accounts

   You migrate your active charts of depreciation in Customizing for Asset
   Accounting under Migrate Charts of Depreciation.

   Other Activities

   Before you can actually use new Asset Accounting, you have to perform
   the following steps from the sequence of steps listed above.

   In your Customizing system, these are the following steps:

   o   Step 5: Make additional manual settings in Customizing for new Asset Accounting. See Perform Additional Manual Activities.

   o   Step 6: Check the prerequisites for activating new Asset Accounting and

   o   Step 7: Activate new Asset Accounting
