Abstract

Methods, systems, and apparatus, including computer program products, for implementing a software architecture design for a software application implementing expense reimbursement. The application is structured as multiple process components interacting with each other through service interfaces, and multiple service operations, each being implemented for a respective process component. The process components include an Expense and Reimbursement Management process component, a Due Item Processing process component, a Payment Processing process component, a Payroll Processing process component, and an Accounting process component.

2. The product of claim 1, wherein:

each of the plurality of process components is assigned to exactly one deployment unit among multiple deployment units, and each deployment unit is deployable on a separate computer hardware platform independent of every other deployment unit; and

all interaction between a process component in one deployment unit and any other process component in any other deployment unit takes place through respective service interfaces of the two process components.

3. The product of claim 1, wherein the deployment units comprise:

an expense and reimbursement management deployment unit that includes the expense and reimbursement management process component;

a due item management deployment unit that includes the due item processing process component;

a payment deployment unit that includes the payment processing process component;

a payroll deployment unit that includes the payroll processing process component; and

a financial accounting deployment unit that includes the accounting process component.

4. The product of claim 1, wherein:

each of the process components includes one or more business objects; and

none of the business objects of any one of the process components interacts directly with any of the business objects included in any of the other process components.

5. The product of claim 4, wherein the business objects comprise a business process object.

6. The product of claim 4, wherein none of the business objects included in any one of the process components is included in any of the other process components.

7. The product of claim 1, wherein the inbound process agents comprise a first inbound process agent operable to start the execution of a business process step requested in a first inbound message by creating or updating one or more business object instances.

8. The product of claim 1, wherein the outbound process agents comprise a first asynchronous outbound process agent that is called after a business object that is associated with the first outbound process agent changes.

9. The product of claim 1, wherein the operations comprise synchronous and asynchronous operations.

10. A system, comprising:

a computer system comprising one or more hardware platforms for executing a computer software application;

a plurality of process components, each of the process components being a package of software implementing a respective and distinct business process, the plurality of process components including;

an expense and reimbursement management process component that involves management and monitoring of expenses incurred by employees, and reimbursement of such expenses to employees;

a due item processing process component that involves collection, management, and monitoring of trade receivables or payables and corresponding sales tax or withholding tax;

a payment processing process component that involves processing and management of all payments;

a payroll processing process component that involves execution and monitoring of regular as well as off-cycle payroll processes; and

an accounting process component that records all relevant business transactions for valuation and profitability analysis; and

a plurality of service operations, each service operation being implemented for a respective process component, the operations comprising inbound and outbound operations, the outbound operation for a first process component being operable to send a message to a second process component of the plurality of process components, the second process component having an inbound operation for receiving the message, the passing of messages between an inbound and an outbound operation defining a message-based pair-wise interaction between the respective process components of the respective operations, the pair-wise interactions between pairs of the process components including interactions between;

the expense and reimbursement management process component and the due item processing process component;

a bank statement creation at bank process component and the payment processing process component;

the due item processing process component and the accounting process component;

the payment processing process component and a payment order processing at house bank process component;

the expense and reimbursement management process component and the payroll processing process component;
