A common mistake made by junior consultants is assuming that if inventory is physically present in the warehouse, allocation should always succeed. In reality, physical availability is only the first of many checks.
The system must also check location status (is it locked or on hold?), inventory status (is it allocated to another order or reserved for quality control?), and allocation rules (does the item match the order's specific criteria?).
Explain how you troubleshoot allocation failures by checking allocation logs and verifying search paths. This level of technical debugging is what distinguishes senior consultants from basic users.
