Hi
Dynamic internal table is internal table that we create on the fly with flexible column numbers.
For sample code, please look at this code tutorial. Hopefully it can help you

Yes , you can create a Dynamic Internal table .Just chek out this program .
type-pools : abap.
field-symbols: <dyn_table> type standard table,
<dyn_wa>,
<dyn_field>.
data: dy_table type ref to data,
dy_line type ref to data,
xfc type lvc_s_fcat,
ifc type lvc_t_fcat.
selection-screen begin of block b1 with frame.
parameters: p_table(30) type c default 'T001'.
selection-screen end of block b1.
start-of-selection.
perform get_structure.
perform create_dynamic_itab. *********Creates a dyanamic internal table*********
perform get_data.
perform write_out.
form get_structure.
data : idetails type abap_compdescr_tab,
xdetails type abap_compdescr.
data : ref_table_des type ref to cl_abap_structdescr.
Get the structure of the table.
ref_table_des ?=
cl_abap_typedescr=>describe_by_name( p_table ).
idetails[] = ref_table_des->components[].
loop at idetails into xdetails.
clear xfc.
xfc-fieldname = xdetails-name .
xfc-datatype = xdetails-type_kind.
xfc-inttype = xdetails-type_kind.
xfc-intlen = xdetails-length.
xfc-decimals = xdetails-decimals.
append xfc to ifc.
endloop.
endform.
form create_dynamic_itab.
Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
exporting
it_fieldcatalog = ifc
importing
ep_table = dy_table.
assign dy_table->* to <dyn_table>.
Create dynamic work area and assign to FS
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.
endform.
form get_data.
Select Data from table.
select * into table <dyn_table>
from (p_table).
endform.
Write out data from table.
loop at <dyn_table> into <dyn_wa>.
do.
assign component sy-index
of structure <dyn_wa> to <dyn_field>.
if sy-subrc <> 0.
exit.
endif.
if sy-index = 1.
write:/ <dyn_field>.
else.
write: <dyn_field>.
endif.
enddo.
endloop.
REPORT ZCLUST1 .
Example: how to create a dynamic internal table
The dynamic internal table stucture
DATA: BEGIN OF STRUCT OCCURS 10,
FILDNAME(8) TYPE C,
ABPTYPE TYPE C,
LENGTH TYPE I,
END OF STRUCT.
The dynamic program source table
DATA: BEGIN OF INCTABL OCCURS 10,
LINE(72),
END OF INCTABL.
DATA: LNG TYPE I, TYPESRTING(6).
Sample dynamic internal table stucture
STRUCT-FILDNAME = 'field1'. STRUCT-ABPTYPE = 'c'. STRUCT-LENGTH = '6'.
APPEND STRUCT. CLEAR STRUCT.
STRUCT-FILDNAME = 'field2'. STRUCT-ABPTYPE = 'd'.
APPEND STRUCT. CLEAR STRUCT.
STRUCT-FILDNAME = 'field3'. STRUCT-ABPTYPE = 'i'.
APPEND STRUCT. CLEAR STRUCT.
Create the dynamic internal table definition in the dyn. program
INCTABL-LINE = 'program zdynpro.'. APPEND INCTABL.
INCTABL-LINE = 'data: begin of dyntab occurs 10,'. APPEND INCTABL.
LOOP AT STRUCT.
INCTABL-LINE = STRUCT-FILDNAME.
LNG = STRLEN( STRUCT-FILDNAME ).
IF NOT STRUCT-LENGTH IS INITIAL .
TYPESRTING(1) = '('.
TYPESRTING+1 = STRUCT-LENGTH.
TYPESRTING+5 = ')'.
CONDENSE TYPESRTING NO-GAPS.
INCTABL-LINE+LNG = TYPESRTING.
ENDIF.
INCTABL-LINE+15 = 'type '.
INCTABL-LINE+21 = STRUCT-ABPTYPE.
INCTABL-LINE+22 = ','.
APPEND INCTABL.
ENDLOOP.
INCTABL-LINE = 'end of dyntab. '.
APPEND INCTABL.
Create the code processes the dynamic internal table
INCTABL-LINE = ' '. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = ''aaaaaa''.'. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = ''19970814''.'. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = 1.'. APPEND INCTABL.
INCTABL-LINE = 'append dyntab.'. APPEND INCTABL.
INCTABL-LINE = ' '. APPEND INCTABL.
INCTABL-LINE = 'loop at dyntab.'. APPEND INCTABL.
INCTABL-LINE = 'write: / dyntab.'. APPEND INCTABL.
INCTABL-LINE = 'endloop.'. APPEND INCTABL.
Create and run the dynamic program
INSERT REPORT 'zdynpro'(001) FROM INCTABL.
SUBMIT ZDYNPRO.
DATA: itab TYPE STANDARD TABLE OF spfli,
wa LIKE LINE OF itab.
DATA: line(72) TYPE c,
list LIKE TABLE OF line(72).
START-OF-SELECTION.
*line = ' CITYFROM CITYTO '.
line = ' AIRPTO '.
APPEND line TO list.
SELECT DISTINCT (list)
INTO CORRESPONDING FIELDS OF TABLE itab
FROM spfli.
IF sy-subrc EQ 0.
LOOP AT itab INTO wa.
WRITE: / wa-cityfrom, wa-cityto.
WRITE 😕 wa-airpto.
ENDLOOP.
ENDIF.

Hi,
1.
For this purpose,
in my program,
there is an INDEPENDENT FORM
whose inputs are
TABLE NAME / STRUCTURE NAME
and from those, it consructs dynamic table.
2. Here is the program.
the dynamic table name will be
<DYNTABLE>.
3. U can use this program (FORM in this program)
to generate any kind of internal table
by specifying TABLE NAME .
4.
REPORT abc.
*----
COMPULSORY
FIELD-SYMBOLS: <dyntable> TYPE ANY TABLE.
FIELD-SYMBOLS: <dynline> TYPE ANY.
DATA: lt TYPE lvc_t_fcat.
DATA: ls TYPE lvc_s_fcat.
FIELD-SYMBOLS: <fld> TYPE ANY.
DATA : fldname(50) TYPE c.
*----
parameters : iname LIKE dd02l-tabname.
*----
START-OF-SELECTION.
*----
PERFORM
PERFORM mydyntable USING lt.
BREAK-POINT.
*----
INDEPENDENT FORM
*----
FORM mydyntable USING ptabname.
*----
Create Dyn Table From FC
FIELD-SYMBOLS: <fs_data> TYPE REF TO data.
FIELD-SYMBOLS: <fs_1>.
FIELD-SYMBOLS: <fs_2> TYPE ANY TABLE.
DATA: lt_data TYPE REF TO data.
data : lt TYPE lvc_t_fcat .
DATA : ddfields LIKE ddfield OCCURS 0 WITH HEADER LINE.
*----
CALL FUNCTION 'DD_NAMETAB_TO_DDFIELDS'
EXPORTING
tabname = iname
TABLES
ddfields = ddfields.
.
*----
CONSTRUCT FIELD LIST
LOOP AT ddfields.
ls-fieldname = ddfields-fieldname.
APPEND ls TO lt.
ENDLOOP.
ASSIGN lt_data TO <fs_data>.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = lt
IMPORTING
ep_table = <fs_data>
EXCEPTIONS
generate_subpool_dir_full = 1
OTHERS = 2.
IF sy-subrc <> 0.
ENDIF.
*----
Assign Dyn Table To Field Sumbol
ASSIGN <fs_data>->* TO <fs_1>.
ASSIGN <fs_1> TO <fs_2>.
ASSIGN <fs_1> TO <dyntable>.
ENDFORM. "MYDYNTABLE
