ARS,
I am struggling a bit to get this.
there is a syntax error,
Field "FIELDS_INT-TYPE" is unknown. It is neither in one of thespecified tables nor defined by a "DATA" statement.     
Again you have asked to move to a diffrent table. What is that table and how to build it.
    LOOP AT <f_table_data1> ASSIGNING <f_wa_table_data1>.
      LOOP AT i_fcat INTO l_fcat.
        IF l_fcat-inttype EQ 'P'.
          ASSIGN COMPONENT l_fcat-fieldname
              OF STRUCTURE <f_wa_table_data1> TO <f_field>
              TYPE     fields_int-type
              DECIMALS fields_int-decimals.
        ELSE.
          ASSIGN COMPONENT l_fcat-fieldname
              OF STRUCTURE <f_wa_table_data1> TO <f_field>
              TYPE     fields_int-type.
        ENDIF.
        " Move <f_field> to a new table and use this table for download
      ENDLOOP.
      TRANSFER <f_wa_table_data1> TO p_bkfile.
    ENDLOOP.
