prevent dispalying zero in field catalog

Hello,

There is  a length field of type char and length 15 in my internal table. While creating Fielda Catalog1, I have set NO_ZERO to 'X' and passing NETWR as reference field to field named LENGTH.

I am using dynamic table and field symbol concept to create an internal table from that field catalog. Because of the reference field NETWR, it is showing zero (0.00) when there is no value to display. Please help to resolve this issue.

Thanks,
