ServiceNow usesImport Setsto bring data from various sources (such as CSV files, Excel spreadsheets, or external databases) into ServiceNow tables. Import Sets provide a flexible way to map incoming data into ServiceNow’s database structure.
A. Import Set
Import Setsare atemporary staging tablewhere external data is first loaded.
ATransform Mapis then used to map and transfer data from the Import Set table into thetarget table(e.g., Incident, Change Request, CMDB, etc.).
Common use cases:
Importinguser recordsfrom an external HR system.
MigratingCI datainto the CMDB.
Loadinghistorical incident recordsinto ServiceNow.
B. Update Set
Update Setsare used formoving customizations(such as UI changes, workflows, or scripts) between instances,not for importing data.
C. Data Pack
No such standard featurein ServiceNow called "Data Pack."
Possibly confused withData Sources, which define external data locations but do not perform imports themselves.
D. Transform Set
Incorrect terminology—ServiceNow usesTransform Maps, not "Transform Sets."
Transform Mapsdefine how data in anImport Setis mapped to target tables, but the import process itself is handled byImport Sets.
