ABAP code example for Function Module LIST_MODIFY_LINE_FORMAT

The ABAP code below is a full code listing to execute function module LIST_MODIFY_LINE_FORMAT including all data declarations.

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_list_index
 
 TYPE SY-LISTI ,
it_line_format
 
 TYPE STANDARD TABLE OF LINEFORMAT ,
wa_line_format
 
 LIKE LINE OF it_line_format,
ld_list_line
 
 TYPE SY-LILLI ,
ld_linesize
 
 TYPE SY-LINSZ .


ld_list_index = '123 '. 

"populate fields of struture and append to itab
append wa_line_format to it_line_format.
ld_list_line = '123 '.
ld_linesize = '123 '.
