A transform map is a set of field maps that determine the relationships between fields in an import set and fields in an existing ServiceNow table, such as Incident [incident] or User [sys_user].

After creating a transform map, you can reuse it to map data from another import set to the same table.
The Transform Maps module enables an administrator to define destinations for imported data on any tables. Transform mapping can be as simple as a drag and drop operation to specify linking between source fields on an import set table and destination fields on any table. Use transform mapping to map source and destination fields dynamically.
Transform considerations
- Auto-mapping
- Double-check that fields the system maps automatically are actually required. For example, encrypted passwords probably should not be mapped.
- Mapping reference fields
- If you are mapping reference field data and the sys_id does not exist, the sys_id could potentially appear in the target record as the DisplayValue, and this may be undesirable.
Using multiple transform maps
Multiple transform maps can be applied to a single data source.
Run multiple transforms off a single import set
Users can select multiple transform maps during data import.
The selected transform maps will be executed on the same import set in the order specified.

Transform map scripts
Transform Map scripts allow you to customize import operations using a robust programming interface to introduce advanced logic.
- Explicit Transform Map scripts, which explicitly define mapping relationships
- Transformation Event scripts, which modify the processing of events at different stages of a transformation
