Import Mapping Review

Self-initiated fictional demonstration generated and reviewed by the authoring AI in a local self-test. Not an independent benchmark, customer project, executed import or measured business result.

Scope And Status

Review complete for the supplied three-row fictional sample. The explicit mapping A1 accounts for five target fields and six source columns. No exception was observed against T1-T2 in R1-R3. This is not full-file validation or approval to import. No file, account or record has been changed, and no import has been executed. The empty non-production destination is a supplied condition in T3, not an independently inspected fact.

Mapping Draft

• Target field: sku

  Source: C1 Item code

  Decision: Explicitly supplied

  Supplied rule: Required exact text; preserve leading zeros

  Sample observation: 0012, 0012 and 0040 remain strings; no rewriting to 12 or 40

  Evidence: A1, T1, R1-R3

• Target field: warehouse

  Source: C2 Depot

  Decision: Explicitly supplied

  Supplied rule: Required; W1 or W2

  Sample observation: All three values belong to the supplied set

  Evidence: A1, T1, R1-R3

• Target field: quantity

  Source: C3 Units

  Decision: Explicitly supplied

  Supplied rule: Required integer of zero or more

  Sample observation: 7, 4 and 0 meet the supplied sample rule; zero is not a missing value

  Evidence: A1, T1, R1-R3

• Target field: received_date

  Source: C4 Received on

  Decision: Explicitly supplied

  Supplied rule: Required ISO YYYY-MM-DD; no timezone conversion

  Sample observation: 2026-10-01, 2026-10-02 and 2026-10-03 are valid calendar dates in the required form

  Evidence: A1, T1, R1-R3

• Target field: state

  Source: C5 State

  Decision: Explicitly supplied

  Supplied rule: Required; available or held

  Sample observation: available, held and available belong to the supplied set

  Evidence: A1, T1, R1-R3

Unmapped source column: C6 Comment is intentionally excluded by A1. Its exclusion does not remove a row. No additional target field is invented for it.

Exceptions And Decisions

No unresolved mapping decision is apparent in the supplied material. No sample value conversion is proposed or performed.

The declared exact key is (sku, warehouse), not sku alone (T2). R1 has (0012, W1), R2 has (0012, W2), and R3 has (0040, W1). These are three different sample keys. R1 and R2 are not duplicate inventory records merely because the SKU repeats; do not combine their quantities or remove either row. There is no evidence about keys elsewhere in the unseen file or destination.

T3 specifies create-only and rejects missing required values. All five required target fields are present in each of the three supplied rows. Production use is not authorized.

Human Validation Plan

1. The authorized operator should confirm the intended target version and A1 mapping, then independently confirm that the selected test table is non-production and empty, as T3 assumes. Do not proceed in a production or nonempty table.
2. Preserve the source and use the platform's native validator on a separate three-row test sample. Configure create-only, the five mappings, C6 exclusion and the exact composite key. Reject missing required values rather than filling them.
3. After that human-operated test, reconcile exactly three source rows against three destination rows and match each pair by (sku, warehouse). Compare each of the five mapped values, including the leading zeros, R3's zero quantity, the dates and enum strings. Confirm both 0012 warehouse rows survive separately. This plan is not a claim that the test has occurred.
4. Stop if row counts differ, a required value changes, keys collapse, leading zeros disappear, or any discrepancy lacks an approved explanation. Investigate before considering further validation. Full-file checks and any production authorization require separate work.

Coverage Check

• Rows reviewed: 3 of 3 pasted sample rows; 0 rows discarded, merged or modified. The full-file row count is unknown.
• Target fields reviewed: 5 of 5 supplied fields, all explicitly mapped by A1.
• Source columns accounted for: 6 of 6; five mapped and one intentionally excluded.
• Sample required/type/enum/date checks: performed only against T1. Sample key comparison: performed only against T2.
• Not performed: full-file parsing or validation, destination inspection, cross-file/destination duplicate checks, platform behavior testing or an actual import.
