Setup

The menu is divided into two areas: “Application” and “Setup”.

DATEV Setup

The DATEV setup is divided into the tabs General, BRAG Module Licensing, Export & Import.

Using the menu item “Initialize chart of accounts” the BC chart of accounts can be initialized. In this process, those accounts that are marked as “DATEV automatic accounts” in the DATEV standard charts of accounts SKR03 or SKR04 are marked accordingly. As a rule, this process only needs to be carried out once during system setup.

What is a DATEV automatic account?

Automatic accounts have a program function in DATEV which causes DATEV, on the DATEV side, to calculate the VAT from the gross amount of the posting. The DATEV program posts the amount reduced by tax to the automatic account.

	Initial creation of the DATEV posting key table for the charts of accounts 03/04 → assignment of posting groups. After initialization, the entered posting groups must be checked for existence and the posting matrices adjusted accordingly! See also page “DATEV Posting Keys”.
	Using the menu item “Initialize DATEV posting keys” the Tax Types table is initially filled. See also page “Tax Types”.
	Reset of the indicators in the customer/vendor accounts to “initial” so that, at the next transfer, the customer/vendor accounts are transferred as “New”.
	Using the menu item “Reset customer/vendor DATEV No.” the DATEV account number is determined according to the “DATEV account number assignment” setup. Only customer/vendor accounts for which the DATEV No. is blank are taken into account. As a rule, this function is only executed initially during system setup.

General

The individual fields:

Fields	Description
DATEV Consultant No.	The consultant number is assigned by DATEV and refers, e.g., to a tax consultant. The input can be max. 7-digit numeric.
DATEV Company No.	The client number is assigned by the tax consultant himself. This number can be stored numerically with a maximum of 5 digits.
DATEV File Format	The available format is the DATEV format.
Transfer Gross Tax Values	Define here if the export should be done via gross export (tax compression). With the gross export no separate tax line will be exported, per primary posting the gross amounts and the corresponding DATEV posting key will be exported. In the other procedure, a separate posting line for the tax posting is generated for each posting with tax. (Usually, the DATEV system expects the gross export procedure).
Chart of Accounts	Define here which chart of accounts it is in your NAV system. (Depending on the selected chart of accounts the DATEV App can support the initialization of the accounts - see also "Initialize chart of accounts").
G/L Account No. Length	Specify how many digits (4 or 6) your account numbers have.
DATEV account number assignment	Define here if and how the DATEV account number assignment for debtors and creditors should be done. When creating new customers and vendors in NAV, different DATEV account numbers can be generated according to the following logic: No number assignment: No number is assigned automatically. NAV number: The NAV customer/vendor number is taken over. Number range: The DATEV personal account number is determined from a number range.
DATEV Customer No.	Number range, from which the DATEV personal account number is to be determined. Depending on whether DATEV account numbers are to be assigned automatically (see DATEV Account Number Assignment), they can also be maintained manually in the respective customers/vendors. The procedure is the same for customers and vendors. On the "DATEV" tab of the respective account, the "DATEV personal account number" can be assigned manually.
DATEV Vendor No.	(See DATEV accounts receivable no.)
Filter Customer	The first three digits of the collective account for receivables (wildcards possible)
Filter Vendor	The first three digits of the collective account for liabilities (wildcards possible)
DATEV Cost Center Dimension	NAV dimension from which the cost center is derived during export.
DATEV Cost Unit Dimension	NAV dimension from which the cost object is derived during export.
Export Payment Terms	Indicator that controls whether and how the terms of payment of the respective entry are exported. see also Page Payment Terms No export: The payment terms are not exported. NAV codes: The NAV code of the payment term will be exported. DATEV codes: The DATEV code of the payment term will be exported.
