This field contains a barcode mask for the Barcode No. field in the Barcode table.
You can enter a maximum of 22 characters, both numbers and letters.
A barcode mask is a collection of numbers and alphabetical letters that are replaced with numbers
when the program generates barcodes from the Barcode No. field in the Barcode table.
If numbers are included in the mask, they are not replaced.
The program fills in this field automatically with the Barcode Mask field in the Product group table
when the Product Group Code field is filled in. You can change that mask for the item.
