To define the work area for the text header, use a structure like THEAD:
DATA name_of_textheader LIKE THEAD.
To define the work area of the lines table, use an internal table with the line structure TLINE:
DATA name_of_linetable LIKE TLINE OCCURS n WITH HEADER LINE.
You can use the above short forms for declaring work areas only, if you use release 3.0 or higher. They have the same effects as
DATA BEGIN OF name_of_textheader.
INCLUDE STRUCTURE THEAD.
DATA END OF name_of_textheader.
or
DATA BEGIN OF name_of_linetable OCCURS n.
INCLUDE STRUCTURE TLINE.
DATA END OF name_of_linetable.
