# Keep missing, repeated and unexpected separate

A repeat does not count twice, and 17 never satisfies 000017.

## Keep missing, repeated and unexpected separate

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 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.

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. **Declare the list date**

   Declare the list date.

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

7. **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.

8. **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.

9. **Record the first listed ID**

   Record the first listed ID.

   The exact listed ID counts once. This keyboard submission is a local observation, not proof that goods were loaded.

10. **Keep a repeated scan visible**

   Keep a repeated scan visible.

   A repeated ID does not satisfy another listed carton. The observation stays in history as Already seen.

11. **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.

12. **Review coverage and exceptions**

   Review coverage and exceptions.

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

13. **Inspect each missing ID**

   Inspect each missing ID.

   The remaining expected IDs are listed explicitly. An unexpected scan cannot satisfy them.

14. **Freeze the local summary**

   Freeze the local summary.

   Finishing freezes the current coverage and exceptions. It does not approve a load, confirm carton contents or book despatch.
