Read custodian and location separately
Synthetic device DEV1 is at desk N4. Issue record I1 names S6, but custodian field mistakenly names S7. Both confirm DEV1 stayed at N4. Local correction C1 changes custodian to S6 only, with I1 evidence; no delivery, return or physical transfer occurred.
| Field | Before | After |
|---|---|---|
| Custodian | S7 | S6 under C1 |
| Location | N4 | N4 |
| Movement count | 0 | 0 |
Correct the mistaken association
- Verify DEV1 issue identity
- Record C1 old/new custodian
- Correct S7 to S6
- Check location/movements unchanged
If physical possession differs from I1, investigate it rather than using this clerical correction rule.
How many custody associations and movements change?
Show the worked answer
One association changes; zero movements are added. DEV1 remains at N4.
Keep the movement ledger intact
| Case | Action or result | Evidence boundary |
|---|---|---|
| Change custodian only | Accept with I1/C1 | Clerical error evidenced |
| Add transfer N4→N4 | Reject invented event | No physical transfer |
Retain the mistaken value in the correction trail. Do not edit the original issue actor or insert a handover merely to explain the field change.
