Operations & Research SupportFictional demonstration. All data is invented.
Prepare 4 of 8 fictional variant rows. Hold 3 unresolved rows and exclude 1 exact duplicate.
Eight invented storage and packaging variant rows with inconsistent SKU/option formatting, one missing size and one conflicting SKU pair.
Before and after
| Record | Before | After |
|---|---|---|
| V001 | bin-10-clr ; capacity 10 l; color clear | BIN-10-CLR; Capacity 10 L; Color Clear |
| V006 | Blank size; SKU contains A4 | Held; size remains blank |
| V007 + V008 | Same normalized SKU; different capacity/price | Both held for a decision |
1. What changed
- Trim outer SKU whitespace and uppercase the supplied SKU. Preserve separators and digits.
- Apply the explicit demo option labels Capacity, Size and Color.
- Use only the supplied demo value map: 10/20/30/45 l to the same value with L; A5 stays A5; clear/blue/natural/gray become Clear/Blue/Natural/Gray.
- Preserve product IDs and prices. No dimensions, inventory, images or missing options are invented.
- Exclude only exact duplicates across all raw business fields, ignoring source row ID and dataset label.
- Hold a missing required option value. Never infer a size from a SKU.
- Hold both rows when a normalized SKU points to conflicting variant details.
2. Calculations and checks
- 8 input rows = 4 ready + 3 held + 1 exact duplicate.
- V005 exactly duplicates V004.
- V006 is held for a missing size. V007 and V008 are held for conflicting details under CRATE-30-GRY.
- Every source row is represented exactly once as ready, held or duplicate.
- Prepared SKUs are unique and every prepared row has both option values.
- Every prepared price and product ID matches its source.
- Blank size stays blank in exceptions; conflicting SKU rows are retained for review.
3. Decisions still needed
- V006: supply the size.
- V007 and V008: confirm the correct SKU or the correct capacity and price for each variant.
- Agree on the destination platform template before testing an import.
Limits of this example
- This is a generic review template. No production import or platform integration has been tested or validated.
- Prepared rows follow only the clearly defined demo option map. Real catalogs may require additional fields or rules.
- dataset_label and source_row_id are audit columns. Map or omit them only after the target template is agreed.
