Duplicate fields

Imported from previous forum

Is possible to have duplicate fields in a fix 4.2 message please?

What I mean is

I know the following is valid (repeating group and it has 2 entries)

…146=2;55=ABC;56=2;55=CBA;56=3;…

but is this valid?

…146=1;55=ABC;55=ABC;

Thanks

Duplicate tags (not part of a repeating group ) should not be used in a FIX message since based on the counter party system implementation you may end up with a replaced, corrupted or a concatenated result value.
