Consistent interface for invoice schedule and invoice schedule processing log

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 notifying of an invoice schedule, including a schedule for processing invoices with specifications concerning invoice dates and amounts to be invoiced, 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 invoice schedule notification message entity;
• and
• an invoice schedule package including an invoice schedule entity, wherein the invoice schedule entity includes a universally unique identifier;
• 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 invoice schedule processing logs, 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 notifying of an invoice schedule processing log, including log information created during automatic processing of invoice schedules, the log information describing error situations to be manually solved by a user responsible for business transaction documents defining the invoice schedules, the first message including a message package hierarchically organized as:
• an invoice schedule processing log notification message entity;
• and
• an invoice schedule processing log package including an invoice schedule processing log entity, wherein the invoice schedule processing log entity includes an invoice schedule processing log universally unique identifier (UUID), system administrative data and a status;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.
