Consistent interface for production confirmation

A computer readable medium including program code for providing a message-based interface for exchanging information about production confirmations, 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 a query about an overview of production confirmation inventory change items, the first message including a message package hierarchically organized as:
• a production confirmation inventory change item overview simple by elements message entity;
• a production confirmation inventory change item overview simple selection by elements package including a production confirmation inventory change item overview simple selection by elements entity, wherein the production confirmation inventory change item overview simple selection by elements entity includes at least one of the following:
• at least one selection by inventory location inventory type code, at least one selection by inventory location logistics area universally unique identifier (UUID), at least one selection by inventory location logistics area key ID, at least one selection by inventory location logistics area key site identifier (ID), at least one selection by inventory location inventory managed logistics area UUID, and at least one selection by inventory location permanent establishment UUID;
• and
• a processing conditions package including a processing conditions entity;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.
