ABAP code example for Function Module KL_PROT_VARBEL

The ABAP code below is a full code listing to execute function module KL_PROT_VARBEL 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(ld_level) = Check type of data required

DATA(ld_lines) = 'Check type of data required'.
 

SELECT single VARREGID 
  FROM KLREGDEF 
  INTO @DATA(ld_var_id).


DATA(ld_wa_variables) = 'Check type of data required'.
.

CALL FUNCTION 'KL_PROT_VARBEL'
  EXPORTING
*   level =                      ld_level

    var_id =                     ld_var_id

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_level
 
 TYPE SPROT-LEVEL ,
ld_lines
 
 TYPE I ,
ld_var_id
 
 TYPE KLREGDEF-VARREGID ,
ld_wa_variables
 
 TYPE KLBKNZANDCAT .



ld_level = Check type of data required
ld_lines = 'Check type of data required'.

SELECT single VARREGID 
  FROM KLREGDEF 
  INTO ld_var_id.

ld_wa_variables = 'Check type of data required'.
