creating multiple dynamic internal tables

[Former Member]

hi,

I have requirement where the user is going to enter the table names in the select-option note its not parameter its select option so the user can enter more than one table name. so based on this tables how do i create multiple dynamic internal table names.

Hi,

Check the below program to create dynamic internal table

REPORT zcdf_dynamic_table.

• Dynamic ALV Grid with Cell Coloring.

• Build a field catalog dynamically and provide the ability to color

• the cells.

• To test, copy this code to any program name and create screen 100

• as described in the comments. After the screen is displayed, hit

• enter to exit the screen.

• Tested in 4.6C and 6.20

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_cellcolors TYPE LINE OF lvc_t_scol,

wa_is_layout TYPE lvc_s_layo.

FIELD-SYMBOLS:

<t_dyn_table> TYPE STANDARD TABLE,

<wa_dyn_table> TYPE ANY,

<t_cellcolors> TYPE lvc_t_scol,

<w_field> TYPE ANY.

START-OF-SELECTION.

• Build field catalog based on your criteria.

wa_fieldcat-fieldname = 'FIELD1'.

wa_fieldcat-inttype = 'C'.

wa_fieldcat-outputlen = '10'.

wa_fieldcat-coltext = 'My Field 1'.

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.

hi,

my question is i have to create multiple fieldcatalog names based on the table names as well multiple dynamic internal table names.

select tabname from dd03L into T_DD03L where tabname in S_TABNAME.

delete adjacent duplicates from T_DDO3L.

loop at T_DD03l into W_DDO3L

call function REUSE_ALV_FIELDCATALOG_MERGE

exporting

I_INTERNAL_TABNAME = W_DD03L-TABNAME

changing

CT_FIELDCAT = T_FIELDCAT.

endloop.

*... Create the dynamic internal table

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = T_FIELDCAT

IMPORTING

ep_table = new_table.

now my question is since iam looping through T_DD03L so there will be multiple table names so for every table name there should be different field catalog generated as well as dynamic table generated so how i generate new names for every loop.
