ABAP code example for Function Module VIEW_WRITE_CHANGELOG_HEADER

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

 

SELECT single TABNAME 
  FROM TVDIR 
  INTO @DATA(ld_viewname).

 

SELECT single FLAG 
  FROM TVDIR 
  INTO @DATA(ld_bastab).

 

SELECT single FLAG 
  FROM TVDIR 
  INTO @DATA(ld_begin).


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

CALL FUNCTION 'VIEW_WRITE_CHANGELOG_HEADER'
  EXPORTING
    viewname =                   ld_viewname
    bastab =                     ld_bastab
    begin =                      ld_begin
    clidep =                     ld_clidep
    .  "  VIEW_WRITE_CHANGELOG_HEADER

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_viewname
 
 TYPE TVDIR-TABNAME ,
ld_bastab
 
 TYPE TVDIR-FLAG ,
ld_begin
 
 TYPE TVDIR-FLAG ,
ld_clidep
 
 TYPE CLIDEP .



SELECT single TABNAME 
  FROM TVDIR 
  INTO ld_viewname.


SELECT single FLAG 
  FROM TVDIR 
  INTO ld_bastab.


SELECT single FLAG 
  FROM TVDIR 
  INTO ld_begin.

ld_clidep = 'Check type of data required'.
