What are field symbols and field groups? Have you used component idx of structure with field groups?
A field symbol does not physically reserve space for a field, but points to a field which is not known until runtime of the program. Field symbols are comparable to the concept of pointers as used in the programming language C.An extract dataset consists of a sequence of records. These records may have different structures. All records with the same structure form a record type. You must define each record type of an extract dataset as a field group, using the FIELD-GROUPS statement.
