ABAP code example for Function Module LIFNR_CHECK

The ABAP code below is a full code listing to execute function module LIFNR_CHECK 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).

DATA:
it_t_knvp  
 
 TYPE STANDARD TABLE OF KNVP,"TABLES PARAM
wa_t_knvp
 
 LIKE LINE OF it_t_knvp

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_c_knvp
 
 TYPE KNVP ,
ld_i_actual_line
 
 TYPE I ,
it_t_knvp
 
 TYPE STANDARD TABLE OF KNVP ,
wa_t_knvp
 
 LIKE LINE OF it_t_knvp,
ld_c_ktonr
 
 TYPE RF02D-KTONR ,
ld_i_tpar
 
 TYPE TPAR ,
ld_i_msg_handling
 
 TYPE C .


ld_c_knvp = 'Check type of data required'.
ld_i_actual_line = 'Check type of data required'. 

"populate fields of struture and append to itab
append wa_t_knvp to it_t_knvp.

ld_c_ktonr = some text here
ld_i_tpar = 'Check type of data required'.
ld_i_msg_handling = 'Check type of data required'.
