Hi,

You can do as following

loop at lt_table into ls_area.

wa_fc-fieldname = ls_area-column1.
wa_fc-datatype = 'STRG'.

append wa_fc to it_fc.
clear wa_fc.

endloop.

* Create dynamic internal table and assign to FS
CALL METHOD cl_alv_table_create=>create_dynamic_table
        EXPORTING
               it_fieldcatalog = it_fc
               i_length_in_byte = 'X'
        IMPORTING
               ep_table         = dy_table.

ASSIGN dy_table->* TO <dyn_table>.

Now that creates an internal table, if you want work area you could do that following

* Create dynamic work area and assign to FS
CREATE DATA dy_line LIKE LINE OF <dyn_table>.
ASSIGN dy_line->* TO <dyn_wa>.

Hi,

If you observe the parameters of mentioned method, it is clear that

It_fc should be of type LVC_T_FCAT,

wa_fc should be of type LVC_S_FCAT

Hi,

FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE.

DATA: dy_table TYPE REF TO data,

* Create dynamic internal table structure

CREATE DATA dy_table TYPE TABLE OF (p_table).

ASSIGN dy_table->* TO <dyn_table>.

* p_table required Table name
