Hi Prabhu,

Here it is..

step1.Build an field catelog which should consist of all the fields which u want in internal table.

step2.Call the method

step3.Create work area..

Sample Code:

data: t_fieldcat TYPE lvc_t_fcat,

wa_fieldcat TYPE lvc_s_fcat.

wa_fieldcat-tabname = 'EKKO'.

wa_fieldcat-fieldname = 'EBELN'.

wa_fieldcat-datatype = 'CHAR'.

wa_fieldcat-intlen = '10'.

APPEND wa_fieldcat TO t_fieldcat.

CLEAR : wa_fieldcat.

wa_fieldcat-tabname = 'EKPO'.

wa_fieldcat-fieldname = 'MATNR'.

wa_fieldcat-datatype = 'CHAR'.

wa_fieldcat-intlen = '18'.

APPEND wa_fieldcat TO t_fieldcat.

CLEAR : wa_fieldcat.

*-----Building Dynamic internal table.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = t_fieldcat

IMPORTING

ep_table = dy_table.

ASSIGN dy_table->* TO <t_paymord>.

*-----Creating work area for dynamic internal table

CREATE DATA: dy_line LIKE LINE OF <t_paymord>.

ASSIGN: dy_line->* TO <w_paymord> .

LOOP AT <t_paymord> INTO <w_paymord>.

Endloop.
