Campaign Import Grain Duplicate Review

Detect repeated cost-row keys without treating every duplicate campaign name as an error. Preparation only, not an account action.

What to provide

Approved import grain, dimensions, daily cost rows, source versions and duplicate treatment policy.

How it works

1. Construct keys from the documented full grain, including date and required dimensions.
2. Separate identical repeated rows from different dimensions and conflicting values under the same key.
3. Show candidate double-count amounts without deleting or merging records.
4. Return a review report; no import, advertiser change or automatic correction is authorized.

The output

full key | row IDs | dimensions | exact repeat/conflict | amount at risk | owner review

Worked fictional example

Fictional same date/campaign/device key appears twice at cost 20: candidate duplicate 20. Mobile 20 and desktop 20 remain separate if device belongs to the grain.

Checks and limits

Keep source versions and original values. Unknowns stay unknown. Use qualified review for regulated, legal or hiring decisions. No live account compatibility test, send, share, schedule, ledger change or payment is authorized.
