Capture the ordered and observed identities
The synthetic order requests eight blue sleeves, item SL-B. Eight red sleeves, SL-R, arrive instead. The supplier has agreed a swap, not a substitution. Record observed marks and a photo before placing the red units in the wrong-item area.
| Event | Item / quantity | Evidence | Order effect |
|---|---|---|---|
| Arrival WA-A | SL-R / 8 | Marks R; photo WA-A | SL-B still unreceived |
| Collection RC-A | SL-R / 8 | Supplier handover RC-A | Wrong-item hold closed |
| Correction DN-B | SL-B / 8 | Identity and condition checked | Receive SL-B / 8 |
Link the swap as two physical events
- Compare order with observed marks
- Hold wrong item
- Record supplier collection
- Inspect corrected arrival
- Receive correct item
If the corrected arrival is also wrong, retain a new discrepancy reference; do not close the requested item merely because a second delivery occurred.
Keep WA-A, RC-A and DN-B linked to the same purchase line. Rewriting SL-R as SL-B would hide what physically entered and left the warehouse. A later decision to accept a substitute needs its own item mapping and permission, rather than being implied by the return agreement.
Before DN-B arrives, what is the received quantity of SL-B?
Show the worked answer
Zero. Eight SL-R units were held and then returned; neither event receives SL-B. Only the checked DN-B can complete the eight-unit purchase line.
