GENERAL LEDGER总账
General Ledger in S/4H is based in the Universal Journal; the line items are stored in the new database table ACDOCA, optimized to SAP HANA.
总账基于统一日记账，所有行项目数据存储于ACDOCA表，统一日记账（Universal Journal）由Header表（BKPF）和行项目表（ACDOCA）组成
You can migrate Ledgers of New General Ledger of the Business Suite or the Classic General Ledger GL to the Universal Journal in S/4H. Please note, that
the number of Ledgers and the configuration of its currency will stay; it is not possible to introduce new ledgers or new currencies during the migration to S/4H. If Classic General Ledger was used, the ledger '00' is migrated to the new leading ledger '0L' of the universal journal.
As Controlling is now part of the Universal Journal as well, now all CO internal actual postings are visible in General Ledger as well. The secondary cost elements are part of the chart of accounts.
成本控制成为统一日记账的组成部分，所有实际成本数据在总账中是可见的，次级成本要素也变成了总账科目。
There is no longer a need for Co realtime integration for transfer of secondary CO postings to NewGL or the Reconciliation Ledger of Classic GL. It is not possible to introduce new currencies in GL during the migration to S/4H.
原 COEP，FAGLFLEXA，ANEP，MLIT 等数据存储在ACDOCA中
-ACDOCA表包含了GL、CO、AA、ML、PA的所有字段
The order (resp. technical fieldnames in table ACDOCA) of the currencies
might change during the migration from Classic or New GL, as the the currency type of the controlling are will determine the second currency (fieldname KSL), but the compatibility view for classic or New GL garantuee that the reporting based on these structures shows the same result as
before.
DOCLN扩充为6位，支持一张财务凭证的行项目数从999增加到999999。
Required and Recommended Action(s)
Mandatory application configuration steps related to General Ledger.
IMG -> Preparation and Migration of Customizing for the General Ledger
The step "Migrate General Customizing" migrates all important customizing around ledgers, currencies and CO integration. It is important to carry out this step before manual changes are done in the img activities below this activity.
Therefore we recommend to go though all activites of "Preparation and Migration of Customizing for the General Ledger" in its sequence in the UI.
Please use the consistency check (Execute Consistency Check of General Ledger Settings, txFINS_CUST_CONS_CHK) and clean up all inconsistencies prior to the migration of tranactional data. If the consistency check raises messages for company codes, which are not used productively, you can
exclude these by activating the flag "Template" in view V_001_TEMPLATE.
