Example from Wikipedia:
* First define structured type TYPES: BEGIN OF t_vbrk, VBELN TYPE VBRK-VBELN, ZUONR TYPE VBRK-ZUONR, END OF t_vbrk. * Now define internal table of our defined type t_vbrk DATA : gt_vbrk TYPE STANDARD TABLE OF t_vbrk, gt_vbrk_2 TYPE STANDARD TABLE OF t_vbrk. "easy to define more tables * If needed, define structure (line of internal table) * Definition with type or with reference to internal table: DATA : gs_vbrk TYPE t_vbrk, gs_vbrk2 LIKE LINE OF gt_vbrk2. * You can also define table type if needed TYPES tt_vbrk TYPE STANDARD TABLE OF t_vbrk.
