Account length and chart of accounts
The G/L account length and the chart of accounts are two independent settings of your client in DATEV:
- Chart of accounts
- The chart of accounts (for example, SKR03 or SKR04) defines which account number has which meaning. Revenue with 19 % VAT, for example, is posted to account
8400in SKR03 and to account4400in SKR04. The chart of accounts therefore determines which account numbers you specify in JustOn for G/L Accounts and Collective Accounts. - G/L account length
- The G/L account length defines how many digits an account number has. The standard charts of accounts work with 4-digit G/L accounts. If the G/L account length is extended, DATEV pads the account numbers on the right with zeros, for example,
8400→84000. Personal accounts (debtors and creditors) are always one digit longer than G/L accounts. This is how DATEV distinguishes G/L accounts from personal accounts.
For the configuration, this means:
- The G/L account length does not follow from the chart of accounts. Take the value from the client data in DATEV.
- All account numbers in JustOn must match the configured G/L account length: G/L accounts with the G/L account length, debtor and creditor numbers (for example,
ON_DebtorNo) with one digit more.
Define the chart of accounts before you transfer data to DATEV for the first time. A later change of the chart of accounts requires all account numbers in JustOn to be adjusted. Accounting documents already transferred still contain the accounts of the old chart of accounts. Also note that JustOn Connector for DATEV supports accounting data for deferred income and prepaid expenses only for SKR04.
