Q&A questions answered by Paul Ovigele.

Q: Is CO-PA part of New G/L in S/4 HANA?

A: No, CO-PA is not part of Suite on HANA. Only when you are on S/4 HANA, will Account-Based CO-PA be part of the Universal Journal (which New GL is also a part of).

Q: Do you get any New G/L functionalities automatically with Suite on HANA?

A: If you are on classic G/L with Suite on HANA you will not get any New G/L functionalities.

Q: Do you need to migrate to New G/L at year end if you need Document Splitting?

A: Yes, you need to migrate to New G/L at year end if you need document splitting. Note, as mentioned in the Webcast, the actual migration does not take place at year-end but a few months after. However, the year-end is a cutoff date which determines which postings will be migrated with document splitting and which will be migrated as a balance only.

Q: How long does a typical New G/L implementation take?

A: It depends on the number of company codes and the functionality being implemented. Between six to nine months is probably realistic in most cases.

Q: Can you implement both an extension ledger and a parallel ledger?

A: Yes, you can. They serve different purposes. Parallel ledger is normally used for Legal reporting purposes, while the extension ledger is normally used for management reporting purposes.

Q: Can you explain if future BSEG BKPF table will be replaced by ACDOCA?

A: BSEG and BKPF are not replaced by ACDOCA. They still exist in S/4 HANA, and contain some of the same limitations. However, ACDOCA replaces GLT0, GLPCA, COEP, etc.

Q: Are extension ledgers used for local reporting for local Statutory purposes?

A: Extension ledger can be used for Local reporting, but is more suited for management reporting.

Q: We have been on the classic ledger for nearly 20 years and need to determine if we nee to go to the New G/L prior to the S/4  HANA implementation to reduce risk.

A: This really depends on the situation in your company. The webcast presentation discusses the pros and cons of implementing New G/L functionality before or after S/4 HANA. Remember that New G/L is automatically active when you migrate to S/4. It is the functionality such as Document Splitting and Parallel Ledger that require a separate migration.

Q: If we have New GL and we have to move to S4 HANA.  How the migration steps should be carry out?

A:

Q: If you choose option 1 and turn on document splitting later, does that have to coincide with a FY migration date?

A: The migration will be a typical S/4 HANA migration, with the New G/L tables (e.g. FAGLFLEXT) being replaced with the Universal Journal table (ACDOCA). If you are already on New G/L before moving to S/4 there will be greater compatibility because the New G/L tables already combine a few Classic tables such as GLPCA, GLFUNCT. etc.

Q: For a Company with Jan-Dec Fiscal Year, hwat is the average month of data they usually have to migrate after document splitting has been configured?

A: The rule is that, any accounts that are open-item managed will have ALL the data migrated to document splitting, while non-open item managed accounts will have only balances brought over. This means that if an open managed account has data from 10 years ago, all this data will be migrated. This is why it is recommended to clear as many open items as possible before the migration so that the runtime is not impacted. For the current year (e.g. For Jan to Dec 2018, you actual Migration will probably be in April 2019) all documents will be migrated.

Q: The Migration cockpit service in Phase 2, does it takes data from Classic GL after the migration date until the activation date and moves the data to either FAGL or ACDOCA form GLT0?

A: Note, no migration is done on phase 2 (unless you are subsequently implementing document splitting). The migration is done in phase 1 during the migration weekend. During this time, all the data before and after the migration date are transferred to FAGL or ACDOCA. Think of the migration date as a cutoff point that determines how the documents will be migrated. 

Q: For option 1  - new GL migration, will it be the same approach if without SoH Migration (Run with Classic).

A: It will typically be the same in terms of functionality. However, since you will not be on a HANA database the migration runtime will be slower.

Q: We are using new GL and document splitting is activated, but we are planning to create more ledgers, is it good for after S4 upgrade or before S4 upgrade.

A: If your S/4 HANA upgrade is imminent, I would suggest waiting until after you migrate as you will have more flexibility with the ledgers.

Q: Three options were provided for going to NEW GL and S4HAHA.  Is one option recommended or strongly preferred over the others?

A: It depends on the organization's situation, budget, other conflicting projects in the pipeline, and so on. It is easier to migrate to S/4 HANA if you are already on New G/L, but there could also be downsides of migrating to New G/L first if the organization is not prepared for the change.
