When using the inventory tool while checking the box "on export as csv", barcode not found are exported in the csv. However, when using the inventory tool and exporting as a csv the results, barcodes are not exported. This is normal because they are displayed as notification and not in the array. It is a bit weird to have 2 different behaviours. A solution would be to append the errors in the array of results. Should we maybe have a syspref to decide if we append or not ? Can we consider that the not exported array should always have contained the barcode error ?
