You can create dynamic internal tables using..

field-symbols: <table> type any.

types: fieldref type ref to data.

data: dyn_table type fieldref.

As for the actual code to generate the table:

create data dyn_table type (SAP Table).

assign dyn_table->* to table.

REPORT zselect_dynamic LINE-SIZE 132

LINE-COUNT 65(1)

NO STANDARD PAGE HEADING

MESSAGE-ID z1.

TYPES ztab LIKE dcobjdef-name .

PARAMETERS: tab_name TYPE ztab DEFAULT 'Z?????' ,

tab_nam2 TYPE ztab DEFAULT 'Z?????' ,

pclient AS CHECKBOX .

SELECTION-SCREEN SKIP .

PARAMETERS: where1(80) ,

where2(80) ,

where3(80) ,

where4(80) .

*

DATA : lcode(72),

prog_tab LIKE lcode OCCURS 0 WITH HEADER LINE .

DEFINE append_line.

append &1 to prog_tab.

END-OF-DEFINITION.

DATA: BEGIN OF nametab OCCURS 0.

INCLUDE STRUCTURE dntab.

DATA: END OF nametab.

DATA: BEGIN OF twhere OCCURS 20,

line(80),

END OF twhere.

DATA: zprogram LIKE sy-cprog,

no_line TYPE i,

zmessage(150) ,

count_commit TYPE i .

DATA: d_ref TYPE REF TO data,

d_ref2 TYPE REF TO data ,

lt_alv_cat TYPE TABLE OF lvc_s_fcat,

ls_alv_cat LIKE LINE OF lt_alv_cat.

FIELD-SYMBOLS : TYPE table,

,

,"TYPE ANY ,

Hi,

You can create a simple dynamic table using this piece of code.

Code

data: i_table type ref to data.

field-symbols : <list> type table .

call method cl_alv_table_create=>create_dynamic_table

exporting

it_fieldcatalog = lt_alv_cat

importing

ep_table = i_table .

assign i_table->* to <list> .

Hi

refer this link for simple example

http://www.sap-img.com/ab030.htm

[hymavathi_oruganti]

for creating dynmic int table follow the following steps.

example:

data: begin of itab occurs 0,

sno type i,

sname(10),

marks type i,

end of itab.

Now my requirement is like below, marks should become headings of alv grid.

we donno how many marks will come. so , the requirement is dynamic.

sno| sname| 80 | 90 | 78 | 77...........

build a LVC fieldcat like below.

ls_fieldcat-fieldname = 'SNO'.

ls_fieldcat-col_text = 'SNO'.

append ls_fieldcat to lt_fieldcat.

ls_fieldcat-fieldname = 'SNAME'.

ls_fieldcat-col_text = 'SNAME'.

append ls_fieldcat to lt_fieldcat.

*******for marks*********

loop at itab

ls_fieldcat-fieldname = itab-marks.

ls_fieldcat-col_text = itab-marks.

append ls_fieldcat to lt_fieldcat.

endloop.

**************

2. NOW THE FIELDCAT IS UILT. WE HAVE TO BUILD AN INTERNAL TABLE FROM THE FIELDCAT.

DATA: DREF TYPE REF TO DATA,WA_REF TYPE REF TO DATA.

FIELD-SYMBOLS: <TEMP_TAB> TYPE TABLE, <TEMP_WA> TYPE ANY.

CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE

EXPORTING

IT_FIELDCATALOG = LT_LVCFIELDCAT

IMPORTING

EP_TABLE = DREF.

ASSIGN dref->* TO <TEMP_TAB>.

<temp_tab> is the dynamic internal table built from fieldcat.

3. NOW FILL THE DYNAMIC INTERNAL TABLE.

CREATE DATA WA_REF LIKE LINE OF <TEMP_TAB>.

ASSIGN WA_REF->* TO <TEMP_WA>.

LOOP AT ITAB.

MOVE-CORRESPONDING ITAB TO <TEMP_WA>.

APPEND <TEMP_WA> TO <TEMP_TAB>.

CLEAR IT_ITAB.

ENDLOOP.

ENDFORM. " FILL_DYN_TAB
