Consistent Interface for Business Transaction Authorisation Request and Rejected Direct Debits Post Processing Initiation Run

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

• at least one processor operable to execute computer readable instructions embodied on non-transitory media;
• a graphical user interface executable by the at least one processor and comprising computer readable instructions, embedded on non-transitory media, for requesting to trigger a process to obtain legal authorization of a business transaction by legal authorities, the instructions using a request;
• a first memory storing a user interface controller executable by the at least one processor for processing the request and involving a message including a first message package derived from a common business object model, where the common business object model includes business objects having relationships that enable derivation of message-based service interfaces and message packages, the first message package hierarchically organized, the hierarchical organization of the first message package including hierarchically organized as:
• at a first hierarchical level in the first message package, a business transaction authorization internal request message entity;
• and
• at the first hierarchical level in the first message package, a business transaction authorization internal request package including, at a second hierarchical level in the first message package, a business transaction authorization internal request entity, a party package, and an item package, wherein the business transaction authorization internal request entity includes, at a third hierarchical level in the first message package, a base business transaction document identifier and a creation date, wherein the party package includes, at the third hierarchical level in the first message package, a buyer party entity and a seller party entity, and wherein the item package includes, at the third hierarchical level in the first message package, at least one business transaction authorization internal request item entity, and wherein each business transaction authorization internal request item entity includes, at a fourth hierarchical level in the first message package, an identifier and a type code;
• and
• a second memory, remote from the graphical user interface, storing a plurality of service interfaces executable by the at least one processor and derived from the common business object model to provide consistent semantics with messages derived from the common business object model, wherein one of the service interfaces is operable to process the message via the service interface based on the hierarchical organization of the message package, where processing the message includes unpacking the first message package based on the message package's structure and the message package's derivation from the common business object model, wherein the particular structure of the message package is used at least in part to identify the purpose of the message.

A computer readable medium including program code for providing a message-based interface for exchanging information about rejected direct debits post-processing initiation runs, 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 querying information about rejected direct debits post-processing initiation runs, including unrealized direct debit receivables, the first message including a message package hierarchically organized as:
• a rejected direct debits post-processing initiation run query by elements message entity;
• and
• a rejected direct debits post-processing initiation run package including a rejected direct debits post-processing initiation run entity, wherein the rejected direct debits post-processing initiation run entity includes a company universally unique identifier (UUID), an identifier (ID), system administrative data, and a status;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.

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 querying information about rejected direct debits post-processing initiation runs, including unrealized direct debit receivables, the instructions 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 rejected direct debits post-processing initiation run query by elements message entity;
• and
• a rejected direct debits post-processing initiation run package including a rejected direct debits post-processing initiation run entity, wherein the rejected direct debits post-processing initiation run entity includes a company universally unique identifier (UUID), an identifier (ID), system administrative data, and a status;
• and
• a second memory, remote from the graphical user interface, storing a plurality of service interfaces, wherein one of the service interfaces is operable to process the message via the service interface.
