how to customize barcode data
Not very clear …
Ok. Detailed explanation is mention below.
I want to split barcode value scanned by barcode reader in two parts.
First 6 digits are item code and from 7 to 11 digits are measurement units. remaining digits will be ignored.
I want this customization in 2 different text boxes
You need a custom script for that; you should create one field store the barcode and then, on field value change, split it as you want.
