An implementation team is enhancing the Sales Order Agent for a distributor. When a customer's purchase order requests a quantity that exceeds the available stock for a line item, the operations manager wants the agent to create the order using the available quantity and route the shortfall to a supervisor for manual follow-up, rather than rejecting the whole order. Which configuration achieves this?

The correct answer is C. The operations manager explicitly wants partial fulfillment rather than an all-or-nothing outcome, so the agent needs to split the affected line item into what can be shipped now and a flagged remainder that a supervisor follows up on manually. Option A is incorrect because rejecting the whole order discards the portion of stock that is available and forces the customer to resubmit, which is the opposite of the partial-fulfillment behavior requested. Option B is incorrect because substituting a different product code changes what the customer ordered without their input or approval, introducing a fulfillment error rather than solving the shortage transparently. Option D is incorrect because placing the entire order on hold delays the items that could ship immediately, again failing to deliver the available quantity now, which was the specific outcome the manager asked for. Splitting the line item so the available quantity proceeds while the shortfall is escalated is the only option that matches both parts of the requirement: partial fulfillment now, human follow-up on the gap.
