The system allows for defining structure of account number (number of characters) and attach the defined numeration schemes to particular general accounts.

Account numeration schemes are closely connected with an accounting period and chart of accounts defined in it. In each accounting period it is possible to define different account numeration schemes. Moreover, when transferring/updating the chart of accounts, numeration schemes are copied from previous accounting period.

The list of account numeration schemes is available in menu Configuration → Accounting → Account Numeration.

The list of account numeration schemes is composed of section Account Numeration Schemes, which presents a list of defined numeration schemes and Example of Account Numeration, which presents the preview of the structure of a selected numeration scheme.

To add a new numeration scheme, it is necessary to select [Add] button. A form of a new numeration will appear, where it is possible to determine number of characters on each level of account and select general accounts to which a given scheme will apply.

The form is composed of the following elements:

Name − field used to enter a name of a given numeration

Active − parameter used to uncheck the activity of a numeration scheme. When deactivating a numeration scheme with accounts assigned to it, a user decides whether the associations with book accounts should be deleted as well. An inactive numeration scheme will not be displayed on the list of numeration schemes selected from the level of a book account form.

Levels – table used to enter levels of accounts, composed of the following columns:

• Level − the system automatically enters numbers of levels. For general account it will be digit 1, for subsidiary account – successive numbers.
• Number of Characters – number of characters possible to define on individual levels of an account. The value of the column can be from 1 to 50.
• Limit − available options:
  • Up to this number of characters − after selecting a given value, it will be possible on a given account level to add exactly as many characters as it was selected in the field with number of characters
  • Up to this number of characters − after selecting a given value, it will be possible on a given account level to add exactly as many characters as it was selected in the field with number of characters (neither more nor less).

Accounts − table used to indicate accounts for which a given numeration scheme should be valid.

A numeration scheme can be assigned to an account also from the level of the account form, in tab Additional. Deleting an account from a chart of accounts results in its automatic deletion from the numeration scheme form.

Numeration scheme of a given account can be modified at any moment. A new scheme applies to newly added accounts. Numeration of already existing accounts is not verified, the system only displays an information regarding inconsistency between an account number and newly selected numeration scheme, but it is possible to assign such scheme regardless of setting of account numeration control.

The functionality of numeration schemes allows for defining the form of the control of the correctness of an account number. When adding or modifying an account whose number does not fulfill conditions defined in numeration scheme assigned to it, the system displays an appropriate message depending on selected value of the parameter Account numeration control (System → Configuration → Accounting → section Chart of Accounts).

The control of the correctness of an account number is carried out when:

• adding an account from different levels (e.g. from the level of a journal entry, opening balance, accounting note)
• editing an account
