Topic

ABAP Repository Objects for Bank Communication Types

To enable different types of direct communication with your bank's communication client, your must create the necessary ABAP repository objects and map the XML data in the request and response messages to structures in your SAP ERP system. Since there is no common format for messages used in direct bank communication in China,You Must implement the ABAP repository objects and mapping specific to each bank and each service. This allows the framework of the EPIC program to create the necessary request messages and to process the responses.

The implement a bank-specific service, you create the following as needed:

Implementing classes with their common interface and methodsStructures for entering dialog parameters to be used in the request message( dialog type ); displaying data from the response message as an ALV list table ( output table type ); or for transferring from a response message to other programs( other result type )XML mapping for example, using XSLT transformations Data elements for, for example, dialog parameters.Message classes and messages

为了能够银行通信客户端进行不同类型的直接通信，必须在ERP系统创建必要的ABAP 存储库对象，并将请求和响应消息中的XML数据映射到SAP的结构。由于中国没有银行直接通信的通用消息格式，所以必须实现特定银行的每个服务的ABAP存储对象和映射。这允许EPIC程序的框架可以创建必要的响应消息并处理请求。

为了实施一个特定银行的服务，需要创建以下内容：

用他们的公共接口和方法实施类用于将请求消息( 会话类型 )中输入对话框结构，将响应消息的数据展示为ALV报表，或将响应消息传输到其他程序使用XSLT 转换的XML映射对话框参数的数据元素消息类和消息

In addition you create the following to be able to send payment files to your house banks, that is, request message that contain payment orders:

A Data Medium Exchange Engine( DMEE) format tree for each payment file type for each house bank. You create DMEE format trees using the DMEE transaction.The corresponding Payment Medium Workbench ( PMW ) formats. You create PMW formats in the Customizing for IMG. Financial Accounting under Accounts Receivable and Accounts payable -> Business Transactions -> Outgoing Payments -> Automatic Outgoing Payments -> Payment Media -> Make Setting for payment Medium Formats from Payment Medium Workbench -> Create Payment Medium Formats.

除此之外，为了可以发送付款文件到你的银行，你需要创建以下内容：即：请求消息，包含付款命令。

一个数据媒体交换引擎( DMEE )格式树，用于每个银行的支付文件类型，你可以根据DMEE事务创建DMEE格式树

响应的付款媒介工作台格式，你可以在IMG定制中创建PMW格式，应收账款和应付账款 -> 业务交易 -> 传出支付 -> 自动传出支付 -> 付款媒介 -> 在支付媒体工作台设置支付媒体格式 -> 创建支付媒体格式

The ID-FI-EPIC-CN-EXAMPLE package delivered with Electronic Payment Integration includes sample implementations with sample ABAP repository objects and sample XSLT transformations for Chinese banks and some of their bank services. Sample DMEE format trees and sample PMW formats are also available. You can view the sample DMEE format trees and PMW formats using the DMEE and OBPM1 transactions, respectively. The names of the sample DMEE format trees and PMW formats begin with EPIC_EXAMPLE_CN*.

与电子支付集成一起支付的ID-FI-EPIC-CN-EXAMPLE 包中的实例，包含中国银行以及其他银行服务的ABAP存储库对象和样例XSLT转换实例。样例DMEE格式树和样例PMW格式同样有效，你可以分别通过事务DMEE和OBPM1事务查看查看DMEE格式树样例和PMW格式样例。示例DMEE格式树和PMW格式的名称以EPIC_EXAMPLE_CN* 开头。

You can use these example as the basis for your own development. You can copy these example into your own namespace and redefine the implementations to fit your bank-specific message structures. For more information about the availability of these example, see SAP note 1722840, For more information about what each of the sample implementation classes does, read the class documentation in the system using the SE24 transaction.

Your classes are then called by the EPIC framework if your register the classes and corresponding structures in Customizing. For more information, see information, see the system documentation for the Customizing activities in Customizing for Financial Accounts under Accounts Receivable and Accounts Payable -> Business Transactions -> Country Specifics -> China -> Electronic Payment Integration
您可以使用这些示例作为自己开发的基础。您可以将这些示例复制到您自己的名称空间中，并重新定义实现以适应特定于银行的消息结构。有关这些示例可用性的更多信息，请参见SAP注释1722840。有关每个示例实现类所做的更多信息，请阅读使用SE24事务的系统中的类文档。

如果你在自定义中注册了类和相应的结构，那么你的类就会被EPIC框架调用。有关更多信息，请参见“应收账款和应付账款定制->业务交易->国家具体情况->中国->电子支付集成”项下的“为金融账户定制”活动的系统文档

Customizing for Electronic Payment Integration

The Customizing activities specfic to EPI are located in the SAP Customizing implementation Guide( SPRO transaction ) as follows: Financial Accounts( NEW) -> Accounts Receivable and Accounts Payable -> Business Transactions -> Country Specifics -> China -> Electronic Payment Integration. You can also access this Customizing from the Electronic Payment Integration( China ) screen by choosing Environment -> Change Customizing -> Electr. Pay. Int.

To be able to use the Electronic Payment Integration functions, you make the settings described in the following documentation:
