Migration with Document Splitting 

Use

Migration to an environment with document splitting is more complex than the scenario without document splitting. In the case of migration with document splitting, line items must be enriched with account assignment information in order to guarantee that the processing and results of subsequent processes are correct.

You can use document splitting to divide the line items according to selected characteristics (such as by segment). During document splitting, information (account assignments) is generated in line items that do not initially contain this information. In addition, a zero balance setting can be generated for selected characteristics so that it is possible to create at any time complete financial statements for these characteristics.

Prerequisites

Customizing must be set up for document splitting. This applies to the posting of documents in New General Ledger Accounting as well as for the migration.

If you want to manage in the New General Ledger Accounting independent accounting units in addition to the company code (for example, the characteristics Segment, Profit Center, or Fund), you need to ensure that the opening balance sheet amounts to zero for each value of these entities. (In cases involving more than one independent accounting unit, combinations of their values must also be taken into account.)

Activities

You need to perform the following activities for the migration to New General Ledger Accounting:

●      Customize the migration

○       In the New GL Migration Cockpit, create the migration plan and assign company codes to them.

Select the migration type With Document Splitting.

Ensure that document splitting is used in all company codes that are assigned to the migration plan. If you do not want to use document splitting for specific individual company codes, you have to migrate these company codes in a separate migration plan. In this scenario, it is not possible to have cross-company-code documents between company codes with and without document splitting.

○       Define the validation date for testing document splitting.

By validating document splitting, you can simulate business processes modeled in New General Ledger Accounting under live system conditions (in the production system). For more information, see Validation of Document Splitting). The prerequisites for this that you have set up New General Ledger Accounting, document splitting in particular has been defined and is active, and the leading ledger has also been set up. During validation, no data is updated to the tables in General Ledger Accounting or to the tables for document splitting. In this way, you can check whether the posting rules defined are adhered to and avoid an accumulation of documents containing errors that need to be posted subsequently.

Before you can activate document splitting, you need to briefly activate New General Ledger Accounting in the migration test environment and then deactivate it again before executing the migration. It is not yet possible to deactivate New General Ledger Accounting at this point because no transaction data yet exists.

Under no circumstances should you transport the activation to the productive environment.

○       Define any alternative settings, where necessary.

The Customizing settings for document splitting should show how the business transactions are generally modeled from the activation event. For the migration, it may be necessary to make special Customizing settings for document splitting that only have the purpose of preparing legacy documents to be subsequently posted.

You can make the following alternative settings:

■       Alternative document splitting method for migration

■       Alternative assignment of business transactions

■       Alternative assignment of item category

■       Alternative clearing relationship (currently delivered in the background)

■       Intervention options using a Business Add-In (BAdI)

●      Create worklists

○       For items still open on the key date that document the balance on the last day of the previous period

○       For documents that are posted on or after the migration date and thereby fall in the current fiscal year.

●      Enrich the open items with account assignment information

A special feature of this migration scenario is that the open items need to be supplemented with account assignment information for document splitting in subsequent processes as described above.

●      Transfer open items from previously created worklist.

In this activity, you have to build the general ledger line items in the new tables and create the balance carryforward (period 0) of the current fiscal year. In this step, you process all G/L accounts managed on an OI basis as well as the reconciliation accounts for customers and vendors.

●      Build document splitting informationon the basis of the general Customizing settings as well as on the basis of migration-specific Customizing settings (optional).

●      Subsequently post documents for current fiscal year from worklist

Using a function for performing subsequent postings, you can update debit/credit totals of G/L accounts by period. This affects all documents in tables BKPF and BSEG that were posted with a posting date >= migration date.

●      Create balance carryforward for all G/L accounts not managed on an OI basis, from the balance carryforward of these accounts in an appropriate source ledger.

This only concerns balance sheet accounts because all P&L accounts were carried forward to the retained earnings accounts at the end of the previous fiscal year.

●      Evaluate the migration status to establish whether the migration was successful.

●      End the migration by setting the migration status to Completed.
