Customer invoicing requires the presence of customers and a remit-to-address. Customers are necessary to identify who the invoice is being issued to, and a remit-to-address is crucial for indicating where payments should be sent.

In reference data assignment, two key determinant types are Business Unit and Project Unit. A Business Unit represents the departments or organizations within an enterprise, providing a structural division for the assignment context. Similarly, a Project Unit serves as a logical organization ensuring consistent project management practices within the enterprise. Both are essential for assigning reference data effectively depending on the organizational structure and project dynamics.

If an adjustment for an invoice exceeds a user's approval limit, the adjustment is set to the status 'Pending Approval' until someone with the appropriate approval authority reviews and either approves or rejects it. Hence, the correct status of the adjustment would be 'Pending Approval'.

When the Create Automatic Billing Adjustments program is run, if any amounts exceed the Billing Specialist's approval limits, the program creates the adjustments with a status of Pending Approval. This allows for further review and approval by an individual with the appropriate approval limits.

When a customer opts to make a payment by a credit card, the receipt is identified as an automatic receipt. This is because the process involves automatically processing the payment through the credit card system, without manual intervention, fitting the description of an 'automatic receipt.'
