1070629 - FAQs: New General Ledger Migration

Read question 23 for  "Running new GL and traditional GL at the same time"

23. You want to configure a new company code with the new general ledger. The existing company codes use the classic general ledger. Can company codes use different general ledgers (classic and new) in the same client?

The implementation of a new company code and the transition from the classic general ledger to the new general ledger are two different projects which you must schedule at different times.
You perform the migration from the classic general ledger to the new general ledger at client level and it affects all company codes in this client.

Because the new general ledger is activated at client level, the new general ledger would be active for all company codes, not only for the new company code. This would mean that the new general ledger is active in the old company codes, but there was no migration from the classic general ledger to the new general ledger. This is not possible.

Therefore, it is not possible to start with a new company code in the new general ledger while the classic general ledger is still active in other company codes in the same client.

First implement the new company code. Then set up the project for the transition from the classic general ledger to the new general ledger.

Alternatively: First set up the project for the transition from the classic general ledger to the new general ledger and migrate the data to the new general ledger, then implement the new company code.

Benefits of New General Ledger over the Classic General Ledger

The new General Ledger in mySAP ERP has the following advantages over the classic General Ledger in R/3 Enterprise:

a) In the new General Ledger, you can display the parallel accounting using parallel accounts (as in R/3) or using parallel ledgers. The FI standard functions and reports are available for all parallel ledgers.

b) The 'Segment' entity and the relevant reporting that are required for segment reporting according to IAS and U.S. GAAP are available in the new General Ledger.

c) In addition, you can enhance the new General Ledger flexibly, that is, you can enter user-defined fields and update the relevant totals. Many standard reports can evaluate the information from the user-defined fields.

d) When you use the new 'Document Splitting' function (online split), you can create financial statements at company code level and, if required, for entities, such as the segment. For each document, the system then creates a zero balance
for the relevant entity, for example, for the segment.

e) As a result, you no longer have to carry out time-consuming reconciliation tasks between FI and CO for the end of period since cross-entity processes are transferred in real-time to the new General Ledger in Controlling. Furthermore, you can, for example, navigate from the financial statements report results or the profit and loss statement report results to the relevant CO report.

f) The new General Ledger uses the same interfaces as the General Ledger in R/3. As a result, users do not require any additional training.

g) Due to the new 'multi-dimensional' aspect in the General Ledger, all data that is relevant for the General Ledger is stored in one environment. As a result, reconciliation tasks, for example, between the general ledger and Profit Center Accounting or the consolidation staging ledger, and processing steps that have to be carried out repeatedly in the individual applications (for example, balance carryforward are no longer required. When you use the new General Ledger, you may not have to use the special ledger anymore.
