ABAP code example for Function Module ICM_READ_TRC_FILE2

The ABAP code below is a full code listing to execute function module ICM_READ_TRC_FILE2 including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

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_icm_filename
 
 TYPE ICM_LINES-LINES ,
it_lines
 
 TYPE STANDARD TABLE OF ICM_LINES ,
wa_lines
 
 LIKE LINE OF it_lines,
ld_icm_last_n_lines
 
 TYPE I ,
ld_icm_first_n_lines
 
 TYPE I .



ld_icm_filename = some text here 

"populate fields of struture and append to itab
