The Lansweeper integration is deliberately read-only for asset data, which surprises people who expect to edit in the app. Worth knowing where the line sits.
From SweepTag you can: browse and search assets across sites, view the detail (30+ fields), generate barcodes for them, create a custom field, and write barcode values back into that custom field.
You cannot: create or delete assets, edit standard fields, reassign ownership, or run bulk operations.
That is not an oversight — writing back into a system of record deserves more care than a barcode app should take on its own.
