Dynamic internal tables using field symbols

[Former Member]

Hello,

Is it possible to create a dynamic table where the no of fields in the internal table can be created dynamically(using field symbols).

Say sometimes internal tables with 10 fields and depending upon the requirement the fields can be dynamically increased or decreased in runtime.

Thanks.

Hi,

Go through the following code....

*Data definitions
*** Tables
data: lt_data type ref to data.
data: lt_fieldcatalog type lvc_t_fcat.

*** Structure
data: ls_fieldcatalog type lvc_s_fcat.

*** Data References
data: new_line type ref to data,
      fs_data type ref to data.

*** Field Symbols
field-symbols: <fs_data> type ref to data,
               <fs_1> type any table,
               <fs_2>,
               <fs_3>.

*Populating the internal table with fieldnames required for our dynamic
*internal table

ls_fieldcatalog-fieldname = 'MANDT'.
append ls_fieldcatalog to lt_fieldcatalog.

ls_fieldcatalog-fieldname = 'CARRID'. "Fieldname
ls_fieldcatalog-inttype = 'C'. "Internal Type C-> Character
append ls_fieldcatalog to lt_fieldcatalog.

ls_fieldcatalog-fieldname = 'CONNID'.
ls_fieldcatalog-inttype = 'N'.
append ls_fieldcatalog to lt_fieldcatalog.

ls_fieldcatalog-fieldname = 'FLDATE'.
ls_fieldcatalog-inttype = 'D'.
append ls_fieldcatalog to lt_fieldcatalog.

ls_fieldcatalog-fieldname = 'PRICE'.
ls_fieldcatalog-inttype = 'P'.
append ls_fieldcatalog to lt_fieldcatalog.

ls_fieldcatalog-fieldname = 'CURRENCY'.
ls_fieldcatalog-inttype = 'C'.
append ls_fieldcatalog to lt_fieldcatalog.

*Calling the method CREATE_DYNAMIC_TABLE
call method cl_alv_table_create=>create_dynamic_table
     exporting
       it_fieldcatalog = lt_fieldcatalog
     importing
       ep_table = fs_data
     exceptions
       generate_subpool_dir_full = 1
       others = 2
		.
if sy-subrc <> 0.
endif.

*Assigning Field-Symbol to our dynamic internal table
assign lt_data to <fs_data>.


*Internal Table is ready, now to put data in that table
*** So <FS_1> now points to our dynamic internal table.

assign fs_data->* to <fs_1>.


*** Next step is to create a work area for our dynamic internal table.

create data new_line like line of <fs_1>.

*** A field-symbol to access that work area
assign new_line->*  to <fs_2>.

*** And to put the data in the internal table
select
      mandt
      carrid
      connid
      fldate
      price
      currency
              from sflight
              into corresponding fields of table <fs_1>.

*** Access contents of internal table
loop at <fs_1> assigning <fs_2>.
do 5 times.
assign component sy-index of structure <fs_2> to <fs_3>.
write:  <fs_3>.
enddo.
skip 1.
endloop.

top-of-page.
write:/5 'FUJITSU CONSULTING COMPANY' inverse color 6,
       50 sy-datum inverse color 6,
       70 sy-pagno inverse color 6.
uline.
