what is dynamic table?

Hi Vinay,

Dynamic table are those whose fields are decided at RUNTIME based on the requirement.

Check this code where we have created a Dynamic Internal table for uploading DATA from Application server.

*----

• Get the structure of the table.

ref_table_des ?=

cl_abap_typedescr=>describe_by_name( wa_file-file_structure ).

tb_details = ref_table_des->components[].

LOOP AT tb_details INTO wa_details.

CLEAR wa_fieldcat.

wa_fieldcat-fieldname = wa_details-name .

wa_fieldcat-datatype = wa_details-type_kind.

wa_fieldcat-inttype = wa_details-type_kind.

wa_fieldcat-intlen = wa_details-length.

wa_fieldcat-decimals = wa_details-decimals.

APPEND wa_fieldcat TO tb_fieldcat.

ENDLOOP.

• Create the dynamic table and assign to FS

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = tb_fieldcat

IMPORTING

ep_table = tb_dynamic.

ASSIGN tb_dynamic->* TO <dyn_table>.

• Create dynamic work area and assign to FS

CREATE DATA wa_line LIKE LINE OF <dyn_table>.

ASSIGN wa_line->* TO <dyn_wa>.

Hi Vinay,

Dynamic table is a kind of internal table that is populated on runtime.

You decide on runtime, what all fields you want in your internal table.

FIELD-SYMBOLS are used to create such an internal table.

Hi,

In a dynamic table the table "coloums" will be determined during the run time.

Sometime they may be a requirement where based on certain conditionds the table field to be displayed in such case dynamic tables are used.
