Dynamic internal table..urgent!!

[Former Member]

Hello all,

I've gone through previous posts but i think what i want is different.

What i want is to create a dynamic internal table.

for example,

if on selection screen I enter 3, I should get and internal table with 3 columns and so on.

Input:-

p_input = 3.

Ouput:-

col1 col2 col3

Is this dynamic nature possible? If yes, how do I fill these 3 columns with data from some other internal table.

Thanks and Regards,

Anup

Hi,

Check this example..

PARAMETERS: p_input TYPE i OBLIGATORY.

START-OF-SELECTION.

DATA: v_fieldname TYPE char30.

DATA: v_char TYPE numc4.

DATA: it_fldcat TYPE lvc_t_fcat.

DATA: wa_it_fldcat LIKE LINE OF it_fldcat.

DATA: gp_table TYPE REF TO data.

FIELD-SYMBOLS: <gt_table> TYPE table.

DO p_input TIMES.

v_fieldname = 'COL'.

v_char = sy-index.

CONCATENATE v_fieldname v_char INTO v_fieldname.

CONDENSE v_fieldname.

CLEAR wa_it_fldcat.

wa_it_fldcat-fieldname = v_fieldname.

wa_it_fldcat-datatype = 'CHAR'.

wa_it_fldcat-outputlen = 5.

wa_it_fldcat-intlen = 5.

APPEND wa_it_fldcat TO it_fldcat .

ENDDO.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING it_fieldcatalog = it_fldcat

IMPORTING ep_table = gp_table.

ASSIGN gp_table->* TO <gt_table>.

CHECK sy-subrc = 0.

To follow up on Naren's solution, you will need to create a separate working area as the table created has no header. This can be done with:

DATA: re_head TYPE REF TO DATA.
FIELD-SYMBOLS: <gt_head>.

CREATE DATA re_head LIKE LINE OF <gt_table>.
ASSIGN re_head->* TO <gt_head>.

You can then move data to <gt_head> and append <gt_head> to <gt_table>.

Hello,

Thanks a lot for your replies. I am struggling with the next part. Now suppose i've one internal table (which is also generated according to input parameter). So when input = 3, internal table will be like this

sy-tabix item value

(=p_input)

1 10 10.00

2 20 20.00

3 30 30.00

an I've a dynamic internal table <gt_table> (as created by the code). I want to move value corresponding to sy-tabix 1 into col1 of <gt_table> and so on.

so output with write statement will be something like this.

col1 col2 col3

10 20 30

I am not able to play around with <gt_table> properly.

Hi,

DATA: re_head TYPE REF TO DATA.

FIELD-SYMBOLS: <gt_head>.

CREATE DATA re_head LIKE LINE OF <gt_table>.

ASSIGN re_head->* TO <gt_head>.

FIELD-SYMBOLS: <FS>.

LOOP AT ITAB.

ASSIGN COMPONENT SY-TABIX OF STRUCTURE <gt_head>

to <FS>.

<FS> = itab-item.

ENDLOOP.

APPEND <gt_head> to <gt_table>.
