How to create internal table dynamically?

[Former Member]

This code might help u

DATA:

gr_structdescr TYPE REF TO cl_abap_structdescr,

gr_tabldesct TYPE REF TO cl_abap_tabledescr,

gr_dref TYPE REF TO data.

FIELD-SYMBOLS:

<gt_table> TYPE STANDARD TABLE.

gr_structdescr ?= cl_abap_structdescr=>describe_by_name( <f_table ).

gr_tabledescr ?= cl_abap_tabledescr=>create( gr_structdest ).

CREATE DATA gr_dref TYPE HANDLE gr_tabledescr.

ASSIGN gr_dref->* TO <gt_table>.

• now field-symbol <GT_TABLE> points to an internal standard

• table with the same structure as the DDIC table specified in

• <F_TABLE>

hi check this example..

report z_dynamic.

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.

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.

&----

---

*& Form write_out

&----

---

• text

----

---

• --> p1 text

• <-- p2 text

----

form write_out .

• 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.

endform. " write_out

Pl. see this sample code...

report z_dynamic.

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.

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.

form write_out .

• 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.
