Script for handling text input from barcode scanner at "material" selection.

Hi,

Using EB database for spare part equipment. When creating the objects we are using a IR-scanner for text input to the "Material" -field. When using the IR scanner for text input it has ha prefix/suffix as this: "%--3011624329--%". Does anyone have a solution for this? Thinking of somthing like a "text-mask-handling-wizard" opened up at the material field...
