Understanding Data Imports in ServiceNow:

When importing data into ServiceNow, you need to determine how incoming datamatches existing recordsto avoid duplication.

Coalescing fieldsare used to identify whether anincoming record already existsin the target table.

Why " Coalesce Fields " is the Correct Answer:

Coalescing means using specific fields as unique identifiersto determine if a record should beupdatedorinserted as a new record.

If a match is found based on the coalesce field, ServiceNowupdatesthe existing record.

If no match is found, anew record is inserted.

Why Other Answers Are Incorrect:

A. Match Fields→ Not an official ServiceNow term related to import sets. Matching is done through coalescing, but " Match Fields " is not the correct terminology.

C. Key Fields→ This is a general database term, but in ServiceNow, " Coalesce Fields " is the term used for identifying unique keys during imports.

D. Sys IDs→ TheSys IDis a unique identifier for each record in ServiceNow, but it is not used for coalescing unless explicitly set as the coalesce field.

Best Practice Solution:

Set asingleormultiplefields ascoalesce fieldsin theTransform Mapto ensure proper data deduplication.

Navigate toSystem Import Sets → Transform Maps, select the relevant transform map, and mark the coalescing fields.
