ITF code prefix with ZERO

Hi All,

Cani use "0" as a prefix for an ITF code? I tried transaction W4ES like nw said, but i can't see what should i configure to allow leading "0" as a prefix for ITF codes.

When ITF code is input with a 14 digit code input with zero, it ignores zero prefix to it and stores it as a 13 digit EAN number.

Regards,

Deepak
