Resolve asset import errors

Validation checks every selected row and labels its proposed action as create, match, skip or error. Review the counts and row-level messages. Correct the source or mapping and validate again when errors remain.

Imports are create-only in this milestone. Existing equipment is not overwritten, and duplicate identities cannot be used to disguise a correction. The approved snapshot is fixed; changing the mapping invalidates the previous preview.

When the error count is zero, confirm that you approve the displayed snapshot and select Confirm and run import. Metra applies the import atomically: either the complete approved set and its audit evidence are committed, or no organisation records are changed. A safe failure code can be shared with support without sharing source values.
