Overview of Migration Process

SAP Simple Finance is based on new General Ledger Accounting (FI-GL (new)). If you were using classic General Ledger Accounting until now, the application data for General Ledger Accounting are migrated with the migration. You cannot perform the migration of Customizing data for Asset Accounting until after you have installed SAP Simple Finance and activated the new general ledger. The latter is prerequisite for the subsequent migration of documents.

Caution Caution

As soon as you have installed SAP Simple Finance, you can no longer post in Asset Accounting. To ensure that migration is successful, it is essential that you make sure that the prerequisites are met and a complete period-end closing was performed before you install SAP Simple Finance. Posting for new Asset Accounting is only possible again after you have completed the migration fully and successfully.

End of the caution.

For Asset Accounting, you have to execute the steps set out in the table for preparation, installation and migration. (More steps are necessary for other applications; however, these are not part of this migration guide for Asset Accounting.)

Step	Additional Information
1. Check Prerequisites for the Migration (Manual)	See the "Prerequisites" section below.
2. Perform period-end closing for Asset Accounting.	See Preparation.
3. In all relevant systems: Start the program for the preliminary check for Asset Accounting (SAP Note 1939592).	See Preparation.
4. Install SAP Simple Finance	See the Administrator's Guide for SAP Simple Finance.
5. Preparatory Steps for Migrating to the Universal Journal Entry	See the corresponding migration guide.
6. Migrate to new Asset Accounting.	See the following sections of the Migration Guide for new Asset Accounting.
7. Migrating Transaction Data (Documents) As a sub-step of the balance migration: Calculate initial depreciation values	See the section Transaction Data (Documents).

Initial Situation

You want to use SAP Accounting powered by SAP HANA with new Asset Accounting. This Migration Guide for new Asset Accounting is relevant for the following starting scenarios:

You have been using classic Asset Accounting up to now.
Until now you have only been using (new or classic) General Ledger Accounting that has to be migrated. However, you have been using neither classic Asset Accounting nor new Asset Accounting, but are planning to implement new Asset Accounting in the future. In this case, you do not have to perform any of the steps mentioned in the Migration Guide for Asset Accounting. After successful completion of the migration, you can define the necessary Customizing settings for new Asset Accounting.

Before you import SAP Simple Finance into your system, you have to ensure that the prerequisites for new Asset Accounting are met.

Prerequisites

Incompatible Components, Business Functions, and Functions

If you want to use new Asset Accounting, you are not allowed to use any of the following components, business functions, or functions:

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).
Real Estate (RE), that is, classic Real Estate Management
You can use Flexible Real Estate Management (RE-FX) instead.
From Funds Management (PSM-FM) or Industry-Specific Component Public Sector (IS-PS): Requests with Reference to Asset
See the instructions in the Administrator’s Guide and the SAP Notes mentioned there when using industry solutions in SAP Accounting powered by SAP HANA.

Prerequisites

General Ledger Accounting:
- You are currently using new General Ledger Accounting with the ledger approach or accounts approach.
- Or you are currently using classic General Ledger Accounting. In this case, your system is converted to new General Ledger Accounting with the migration to SAP Accounting powered by SAP HANA.
You need the new depreciation calculation from the Enterprise Extension Financials Extension (EA-FIN).
To be able to use new Asset Accounting (and, if necessary, also Flexible Real Estate Management (RE-FX)), you must activate - if not yet happened – the Enterprise Extension EA-FIN; this must take place before you install SAP Simple Finance.

You must implement the new depreciation calculation in a separate sub-project.
Check whether you can completely archive documents from non-active 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 to the universal journal entry.

Periodic Asset Postings, Currencies

The following prerequisites must be met with regard to periodic asset postings and currencies:

Make sure that the periodic asset postings (with program RAPERB2000) are completed without errors. After SAP Simple Finance is installed, it is no longer possible to catch up these postings. The program is no longer necessary after the migration and is no longer available.
For the leading valuation of the ledger approach and accounts approach and for parallel valuations of the ledger approach, the following is valid: The parallel currencies in the leading ledger in General Ledger Accounting and in the depreciation areas in Asset Accounting must be the same.
If until now you have 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 implement these areas in a separate project before you install SAP Simple Finance. In such a project, you must first perform the preparatory steps for creating depreciation areas in Customizing; you must then determine the new values for each fixed asset for a newly created depreciation area. Contact your consultant for such a project.
For company codes that are assigned to the same chart of depreciation, the following applies: These company codes are not allowed to differ in number and type from the parallel currencies used in General Ledger Accounting.

More Prerequisites, at the Time of Migration

The following prerequisites also have to be met:

Ensure that there are no update terminations from direct postings in the system.
The following applies for the Call-Up Point of the Migration:
From the viewpoint of Asset Accounting, it is not necessary that you install SAP Simple Finance at the end of the year. You must perform the following activities before installing SAP Simple Finance:
- Perform a complete period-end closing in Asset Accounting for the previous period to be closed. This includes the following activities:
  - Execute the periodic depreciation posting run (RAPOST2000).
  - Reconcile your general ledger with the Asset Accounting subsidiary ledger, both for your leading valuation and for parallel valuations.
  You can get an overview of period-end closing activities - not only of those in Asset Accounting - under Period-End Closing Activities.
- Execute the periodic APC postings (RAPERB2000) completely and without errors; a current time stamp must be set. You should post the periodic APC postings one last time immediately before the installation.
- Run the program for recalculating depreciation (transaction AFAR).
The migration must take place at a time when only one fiscal year is open in Asset Accounting.

You can check which fiscal year is closed in your company code in Customizing for Asset Accounting (New) under Preparations for Going Live Tools Reset Year-End Closing .

Note
After completing the migration, make sure that no fiscal year that is before the migration is reopened in Asset Accounting.

End of the note.
If until now you updated transactions in parallel valuations with different fiscal year variants and want to continue using this update, then you must implement a new representative ledger using the SAP General Ledger Migration Service before you install SAP Simple Finance. For more information about alternative fiscal year variants with parallel valuation, see SAP Note 2220152.
Ensure that no further postings are made in your system.

Recommendation
We recommend that you lock the users.

End of the recommendation.

Program for Preliminary Checks of Prerequisites

To check if the prerequisites outlined are met, you have to check using the newest version of the program for preliminary checks RASFIN_MIGR_PRECHECK. You import this program using SAP Note 1939592before you install SAP Simple Finance in your system. Perform this check in all of your systems - in the Customizing system as well as in the downstream systems (test system and production system).

For more information, see Preparation.

Constraints

The following restriction applies for the migration:

Using the migration program available under Tools, you can automatically migrate your charts of depreciation. If error messages appear stating that an automatic migration is not possible, you have to migrate the charts of depreciation manually.
