In order to be able to add custom barcodes to Objects, an Instance Admin needs to add the $BARCODE property to the object type for which barcodes are needed.
The barcode functionality is disabled by default in the ELN UI. This can be enabled by a lab manager or a group admin with admin right to edit the Settings, as shown below.
After enabling the option, please refresh your browser. The Barcodes Generator will be shown in the main menu under Utilities.
Information on how to use the Barcode functionality in openBIS can be found here: Barcodes
