Hi,
Im using GS1 barcodes and its working fine , I got a new product which has 12 digits GTIN numbers and all other AI are perfect. I edited the GS1 nomenclature to read 12-14 digits having AI (01) . 

If i manually type 01 then 12 digit GTIN , it picks up the item and weight i.e 3102 then weight . it works separately , but when i enter combined barcode i.e 01 ,12-digit GTIN ,3102 weight. It doesnt work. Any possibilty i can make it working ? im using odoo 17 on odoo server so dont have accesss to configuration files
