Consistent interface for accounting entry and project processing view of customer transaction document

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 requesting to replicate a bundle of accounting entries associated with one or more accounting transactions, 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:
• an accounting entry bundle replicate request message entity;
• and
• an accounting entry package including at least one an accounting entry entity, wherein each accounting entry entity includes an external identifier, a company identifier, an accounting document type code, a posting date and a business transaction type code, wherein each accounting entry entity further includes at least one item entity;
• and wherein each item entity includes a debit credit code and a chart of accounts item code;
• 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.

A computer readable medium including program code for providing a message-based interface for exchanging information about project processing views of customer transaction documents, 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 notification of a view of a customer transaction document, the view restricted to items that represent service products that are handled as project-based services or expenses, the first message including a message package hierarchically organized as:
• a project processing view of customer transaction document notification message entity;
• and
• a project processing view of customer transaction document package including at least one project processing view of customer transaction document entity, wherein each project processing view of customer transaction document entity includes a universally unique identifier (UUID), a customer transaction document key, system administrative data, a customer transaction document identifier and a type code;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.
