Set up external codes for AIF

To use Application Integration Framework (AIF) to exchange documents electronically with an external system, you must configure each document to use internal codes or external codes for its field values.

For example, if a sales order document refers to an item number, you must choose whether to use the item number from the standard tables in Microsoft Dynamics AX (an internal code) or an item number not in Microsoft Dynamics AX (an external code). External codes are used when the values from the standard tables will not be used.

External codes are set up in the External codes form and are associated with internal codes in Microsoft Dynamics AX. You create and maintain external codes in the specific forms that process the internal codes in Microsoft Dynamics AX. For example, both internal codes and external codes for item numbers are set up and maintained in the Item details form.

To create external codes, you must specify a code, a description for the code, and the value of the external code. You must also specify whether the code is an officially recognized standard code, such as EAN, ISBN, or ISSN.

You can create several external codes for the same item, account number, warehouse, unit, dimension, or currency. For example, the item number BR-12 might have one external code value that corresponds to a customer's item number and another external code value for its EAN number. If there are several standards for the same country code, you can enter the values according to those standards.

The following table lists the fields for which you can create external codes and the location of their corresponding forms.

Вкратце, внешние коды используются в AIF. Их назначение - в случае, когда код объекта в AX отличается от кода во внешней системе, просто подменить один код на другой в момент выгрузки/загрузки электронных документов.

А чего Вы ожидаете от функциональности внешних кодов? В какой момент они должны использоваться по Вашему дизайну?
