When you’ve added fields to create a data schema for a Lookup Table Revision, you can use upsert operations to create or update the data values for those fields:

- Use [Upsert LookupTableRevisionData](https://docs.m3ter.com/api/lookuptablerevisiondata/upsert-lookuptablerevisiondata) to upsert some or all of a Revision’s field data values.
- Use [Upsert LookupTableRevisionData Entry](https://docs.m3ter.com/api/lookuptablerevisiondata/upsert-lookuptablerevisiondata-entry) to upsert an individual Revision field’s data value.

## Notes

- You can only create or update field data values for DRAFT Revisions.
- You cannot change the field data values for PUBLISHED Revisions.
