HI,
if it is the char please convert to formula using the replacement path using the formula variable.
if it is the direct KF use the NODIM function at formula window.
create the new formula -> create the new formula variable -> choose the replacement path -> select info object with attr values - it will pick the only attr value fo KF.
or
use the RIGHT function at trasformation if it is the char.
Thanks,
Phani.
