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.
