FCC, Adapter not converting all data to xml

Dear Experts,

     FCC, Adapter converting only 56 fields out-of 86 fields.

So in XML i could see only 56 field and remaining, 30 fields were missing.

in those 56 field, if i remove few data, adapter will pick more than 56 fields.

File adapter should pick all 86 fields.

Please help me how to do it.
