When using barcodes to identify your products, it is important to ensure that these codes are unique. Cin7 will run a validation check when you are saving a new or updated product, or running a bulk import/update of products.
To check if there are existing duplicates already in the system there is a report available from the reports library called "Duplicate Barcodes", to add this report to your library, click Manage Reports and Permissions, find the Duplicate Barcode report and click Install (You will need Admin Access) and will list all current products that currently have a barcode which is duplicated in the system.
If a duplicate barcode has been found either via the report or during the validation steps the codes will need to be made unique in order to continue using the products involved.
To change barcodes manually click into the product details page and update the "Barcode" or Size Barcode fields manually. If you are wanting to reassign all barcodes in a full size range then click into each size barcode field and remove the barcode before clicking "Create UPC Barcodes"
We really appreciate your feedback.
