MANAGING CONSISTENT INTERFACES FOR FOREIGN TRADE PRODUCT CLASSIFICATION, SUPPLIER INVOICE BUSINESS OBJECTS ACROSS HETEROGENEOUS SYSTEMS

1 . A computer readable medium including program code for providing a message-based interface for exchanging information for foreign trade product classifications, the medium comprising:

program code for receiving via a message-based interface exposing at least one service as defined in a service registry and from a heterogeneous application executing in an environment of computer systems providing message-based services, a first message for providing a request to maintain a bundle of foreign trade product classifications that includes a message package hierarchically organized as:

a foreign trade product classification bundle maintain request message entity; and

a foreign trade product classification package comprising at least one foreign trade product classification entity, where each foreign trade product classification entity includes a product key, a validity start date, and a customs commodity classification code; and

program code for sending a second message to the heterogeneous application responsive to the first message.

2 . The computer readable medium of claim 1 , wherein each foreign trade product classification entity further includes at least one of the following: an action code, an object node sender technical identifier (ID), a change state ID, a universally unique identifier (UUID), a product quantity conversion quantity, and a product quantity conversion corresponding quantity.

3 . A distributed system operating in a landscape of computer systems providing message-based services defined in a service registry, the system comprising:

a graphical user interface comprising computer readable instructions, embedded on tangible media, for providing a request to maintain a bundle of foreign trade product classifications using a request;

a first memory storing a user interface controller for processing the request and involving a message including a message package hierarchically organized as:

a foreign trade product classification bundle maintain request message entity; and

a foreign trade product classification package comprising at least one foreign trade product classification entity, where each foreign trade product classification entity includes a product key, a validity start date, and a customs commodity classification code; and

a second memory, remote from the graphical user interface, storing a plurality of service interfaces, where one of the service interfaces is operable to process the message via the service interface.

4 . The distributed system of claim 3 , wherein the first memory is remote from the graphical user interface.

5 . The distributed system of claim 3 , wherein the first memory is remote from the second memory.

6 . A computer readable medium including program code for providing a message-based interface for exchanging information for supplier invoices, the medium comprising:

program code for receiving via a message-based interface exposing at least one service as defined in a service registry and from a heterogeneous application executing in an environment of computer systems providing message-based services, a first message for providing a request to check for issues that may occur during the creation of one or more supplier invoices by simulation their creation that includes a message package hierarchically organized as:

a supplier invoice bundle check maintain request message entity; and

a supplier invoice package comprising at least one supplier invoice maintain bundle entity and a party package, where each supplier invoice maintain bundle entity includes a business transaction document type code and a document item gross amount indicator, and where the party package comprises a buyer party entity; and

program code for sending a second message to the heterogeneous application responsive to the first message.

7 . The computer readable medium of claim 6 , wherein the supplier invoice package further comprises at least one of the following: a business transaction document reference package, a location package, a cash discount terms package, a payment control package, an attachment folder package, a text collection package, and an item package.

8 . The computer readable medium of claim 6 , wherein each supplier invoice maintain bundle entity further includes at least one of the following: an action code, an item list complete transmission indicator, an object node sender technical identifier (ID), a change state ID, a medium name, a date, a receipt date, a transaction date, a gross amount, a tax amount, and a status.

9 . A distributed system operating in a landscape of computer systems providing message-based services defined in a service registry, the system comprising:

a graphical user interface comprising computer readable instructions, embedded on tangible media, for providing a request to check for issues that may occur during the creation of one or more supplier invoices by simulation their creation using a request;

a first memory storing a user interface controller for processing the request and involving a message including a message package hierarchically organized as:

a supplier invoice bundle check maintain request message entity; and

a supplier invoice package comprising at least one supplier invoice maintain bundle entity and a party package, where each supplier invoice maintain bundle entity includes a business transaction document type code and a document item gross amount indicator, and where the party package comprises a buyer party entity; and

a second memory, remote from the graphical user interface, storing a plurality of service interfaces, where one of the service interfaces is operable to process the message via the service interface.

10 . The distributed system of claim 9 , wherein the first memory is remote from the graphical user interface.

11 . The distributed system of claim 9 , wherein the first memory is remote from the second memory.
