## Check an exact lookup

1. **Open the query screen**

   Open the query screen.

   A viewer can run read-only queries. A result selects complete sources, not just the matching row.

2. **Add an exact match**

   Add an exact match.

   Data-row filters must match the same row. Use the exact field name and the appropriate value type.

3. **Choose the customer code field**

   Choose the customer code field.

   Field names, case and spaces matter. This column stores the code printed for the customer.

4. **Enter the exact text code**

   Enter the exact text code.

   The value remains text. Leading zeroes are part of the identifier.

5. **Run the lookup**

   Run the lookup.

   Check the returned revision and receipt time. Receiving applications decide whether the age of external data is acceptable.

6. **Try a different exact code**

   Try a different exact code.

   Lower-case text is a different code. This deliberately shows a valid query with no match.

7. **Check the no-match result**

   Check the no-match result.

   A valid no-match result is different from invalid or duplicate data. Check the source, field name and value rather than assuming a default.
