How to fill internal table dynamically

[Former Member]

Hi All,

how to fill internal table dynamically.

for example:

begin of itab occurs 0,

empid like pa0000-pernr,

empname like pa0001-ename,

grade(5),

end of itab.

now i want to append dynamically field itab-grade along with rest fields.

is this possible?? if yes kindly let me know how to do that.

Regards,

Kiran I

Hi kiran,

To fill and create and internal table dynamically you can use this code.

TYPE-POOLS: slis.

DATA: it_fcat TYPE slis_t_fieldcat_alv,

is_fcat LIKE LINE OF it_fcat.

DATA: it_fieldcat TYPE lvc_t_fcat,

is_fieldcat LIKE LINE OF it_fieldcat.

DATA: new_table TYPE REF TO data.

DATA: new_line TYPE REF TO data.

FIELD-SYMBOLS: <l_table> TYPE ANY TABLE,

<l_line> TYPE ANY,

<l_field> TYPE ANY.

is_fieldcat-fieldname = 'FIELD1'.

is_fieldcat-ref_field = 'MATNR'.

is_fieldcat-ref_table = 'MARA'.

APPEND is_fieldcat TO it_fieldcat.

is_fieldcat-fieldname = 'FIELD2'.

is_fieldcat-ref_field = 'SPRPS'.

is_fieldcat-ref_table = 'PA0001'.

APPEND is_fieldcat TO it_fieldcat.

is_fieldcat-fieldname = 'FIELD3'.

is_fieldcat-ref_field = 'BEGDA'.

is_fieldcat-ref_table = 'PA0002'.

APPEND is_fieldcat TO it_fieldcat.

• Create a new Table

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = it_fieldcat

IMPORTING

ep_table = new_table.

• Create a new Line with the same structure of the table.

ASSIGN new_table->* TO <l_table>.

CREATE DATA new_line LIKE LINE OF <l_table>.

ASSIGN new_line->* TO <l_line>.

• Test it...

DO 40 times.

ASSIGN COMPONENT 'FIELD1' OF STRUCTURE <l_line> TO <l_field>.

<l_field> = '12345'.

ASSIGN COMPONENT 'FIELD2' OF STRUCTURE <l_line> TO <l_field>.

<l_field> = 'X'.

ASSIGN COMPONENT 'FIELD3' OF STRUCTURE <l_line> TO <l_field>.

<l_field> = '20030101'.

INSERT <l_line> INTO TABLE <l_table>.

ENDDO.

LOOP AT <l_table> ASSIGNING <l_line>.

• ASSIGN COMPONENT 'field1' OF STRUCTURE <l_line> TO <l_field>.

WRITE / <l_line>.

ENDLOOP.

Hii

data index type i.

loop at it_ztable into wl_ztable.

index = sy-tabix + 9.

read line index field value wl_ztable-ch into w_ch.

modify it_ztable from wl_ztable.

endloop.

instead of sy-tabix u can also sy-index .

also look inot this link..this will answer your question.
