Final answer:
In a Purchasing Process - Level 0 Diagram, 'cash receipts data' would be the least expected data store as it pertains to sales rather than purchasing. Inventory, purchase order, and vendor master data are directly related to the purchasing activities.
Step-by-step explanation:
In the context of a Purchasing Process - Level 0 Diagram, which is part of a business process model, there are certain data stores you would expect to be included. These data stores typically pertain to records that are directly related to the purchasing activities of an organization.
The correct answer to which data store one would least expect to see in a Purchasing Process - Level 0 Diagram is (A) cash receipts data. Cash receipts relate to the inflow of cash into the business, generally from sales or services rendered, and would typically be recorded in the revenue or accounts receivable process rather than the purchasing process.
In contrast, options (B) inventory master data, (C) purchase order master data, and (D) vendor master data are all critical to the purchasing process. Inventory master data tracks the details of items the company has or needs to acquire, purchase order master data records specific details of orders, and vendor master data maintains information about the suppliers from whom the company purchases goods or services.
