SSCC 18 barcode.

(Reposted Question)

1. What is Business standard length of barcodes (printed labels) for SSCC 18. Is it 20 character barcodes or 18 character??

2. Can the length of a barcode (read by a device) be modified before it is displayed on the SAP/RF screen.

For Ex: If we scan a barcode of 20 characters can the device truncate the initial 2 characters (which are 0's in SSCC18) and display only last 18 characters on the screen.

(I am aware that we can append zeros to the barcode scan before displaying)
