Decide the correct ID, normally the payroll number. 2. Edit the wrong side so both match. 3. Delete the stray record only after you have copied what you need. 4. Sync Data, then recalculate. ## Prevent - Use a payroll number as ID. - No leading zeros. - Never reuse an ID for a new person. - Write the ID rule in your HR process. ## A typical scenario A staff member appeared as 15 on the terminal and 015 in the software. Half their punches were in each record. Standardising on 15 and re-syncing combined them. *Illustrative example based on common cases, not a named customer.* ## Common mistakes - Leading zeros. - Reusing IDs. - Different IDs per terminal. - Importing without a check. - No ID rule. ## Quick checklist 1. List both sides 2. Compare 3. Choose the correct ID 4. Edit 5. Sync 6. Recalculate ## Frequently asked questions What happens to old punches under the wrong ID? They stay under that ID. You may need to correct reports manually or merge, depending on the version. Can two terminals have different IDs for one person? They should not. Keep one ID company-wide. Can I change IDs in bulk? Via import/export in Excel carefully, after a backup. Who owns ID rules? HR, with IT enforcing them.
