## Refuse a quantity-like duplicate list

1. **Start a manifest check**

   Start a manifest check.

   Check distinct IDs against a reviewed local list. This synthetic lesson never confirms physical contents or despatch.

2. **Choose a repeated-ID file**

   Choose a repeated-ID file.

   This synthetic file repeats SKU-1. It must be refused rather than converted into a quantity.

3. **Map the exact ID column**

   Map the exact ID column.

   Choose Label for the carton IDs. Leading zeroes remain significant.

4. **Map the descriptions**

   Map the descriptions.

   Choose Text for the description. The Ignore column stays outside the retained snapshot.

5. **Name the manifest snapshot**

   Name the manifest snapshot.

   Give this reviewed snapshot a recognisable name. A name and date are local context, not verified authority.

6. **Confirm distinct physical IDs**

   Confirm distinct physical IDs.

   Confirm that every row is a distinct carton, pallet or serial ID, never a repeated SKU representing a quantity.

7. **Refuse duplicate manifest IDs**

   Refuse duplicate manifest IDs.

   The real manifest validator rejects duplicate IDs atomically. Choose the valid practice list to continue.

8. **Choose the prepared manifest**

   Choose the prepared manifest.

   The prepared CSV enters the real file input. Each listed carton has its own exact ID; this is not a quantity list.

9. **Map the exact ID column**

   Map the exact ID column.

   Choose Label for the carton IDs. Leading zeroes remain significant.

10. **Map the descriptions**

   Map the descriptions.

   Choose Text for the description. The Ignore column stays outside the retained snapshot.

11. **Name the manifest snapshot**

   Name the manifest snapshot.

   Give this reviewed snapshot a recognisable name. A name and date are local context, not verified authority.

12. **Declare the list date**

   Declare the list date.

   This declared source date does not prove that a manifest is current.

13. **Confirm distinct physical IDs**

   Confirm distinct physical IDs.

   Confirm that every row is a distinct carton, pallet or serial ID, never a repeated SKU representing a quantity.

14. **Load the reviewed manifest**

   Load the reviewed manifest.

   The real reader validates three unique IDs and keeps only the mapped columns. A pallet ID never implies its child cartons were checked.

15. **Keep 17 separate from 000017**

   Keep 17 separate from 000017.

   The value 17 is not the listed 000017. Unexpected IDs satisfy no listed carton and remain separate from missing IDs.

16. **Review coverage and exceptions**

   Review coverage and exceptions.

   Review missing, unexpected and repeated observations independently before finishing or exporting.
