Create table data

[Former Member]

Hi,

i use Create data statement for table but in zhr_lt i out structure that i build in se11 is there onother why exept build strcture in se 11?

Regards

CREATE DATA dytable TYPE TABLE OF zhr_lt

ASSIGN dytable->* TO <d>.

Try this code..it creates int. table dynamically based on the database table name given in the selection screen.

Hi Joyjit Ghosh,

Thanks but i cant declare str in my program like

types: begin of itab

....

and use it like :

CREATE DATA dya_table TYPE TABLE OF itab

ASSIGN dya_table->* TO <at_a>.

Try this code..this is another variant for creating dynamic table

REPORT zcdf_dynamic_table.

DATA:

r_dyn_table TYPE REF TO data,

r_wa_dyn_table TYPE REF TO data,

r_dock_ctnr TYPE REF TO cl_gui_docking_container,

r_alv_grid TYPE REF TO cl_gui_alv_grid,

t_fieldcat1 TYPE lvc_t_fcat, "with cell color

t_fieldcat2 TYPE lvc_t_fcat, "without cell color

wa_fieldcat LIKE LINE OF t_fieldcat1,

<wa_dyn_table> TYPE ANY,

• Build field catalog based on your criteria.

wa_fieldcat-fieldname = 'FIELD1'.

wa_fieldcat-inttype = 'C'.

wa_fieldcat-seltext = wa_fieldcat-coltext.

APPEND wa_fieldcat TO t_fieldcat1.

wa_fieldcat-fieldname = 'FIELD2'.

wa_fieldcat-inttype = 'C'.

wa_fieldcat-outputlen = '10'.

wa_fieldcat-coltext = 'My Field 2'.

wa_fieldcat-seltext = wa_fieldcat-coltext.

APPEND wa_fieldcat TO t_fieldcat1.

• Before adding cell color table, save fieldcatalog to pass

• to ALV call. The ALV call needs a fieldcatalog without

• the internal table for cell coloring.

t_fieldcat2[] = t_fieldcat1[].

• Add cell color table.

• CALENDAR_TYPE is a structure in the dictionary with a

• field called COLTAB of type LVC_T_SCOL. You can use

• any structure and field that has the type LVC_T_SCOL.

wa_fieldcat-fieldname = 'T_CELLCOLORS'.

wa_fieldcat-ref_field = 'COLTAB'.

wa_fieldcat-ref_table = 'CALENDAR_TYPE'.

APPEND wa_fieldcat TO t_fieldcat1.

• Create dynamic table including the internal table

• for cell coloring.
