ABAP code example for Function Module GET_WEEKDAY_NAME

The ABAP code below is a full code listing to execute function module GET_WEEKDAY_NAME 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_langu_back  
 
 TYPE SY-LANGU
,
ld_longtext  
 
 TYPE T246-LANGT
,
ld_shorttext

.


DATA(ld_date) = '20210129'.

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

SELECT single WOTNR 
  FROM T246 
  INTO @DATA(ld_weekday_number).

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_langu_back
 
 TYPE SY-LANGU ,
ld_date
 
 TYPE SY-DATUM ,
ld_longtext
 
 TYPE T246-LANGT ,
ld_language
 
 TYPE SY-LANGU ,
ld_shorttext
 
 TYPE T246-KURZT ,
ld_weekday_number
 
 TYPE T246-WOTNR .


ld_date = '20210129'.
ld_language = 'Check type of data required'.

SELECT single WOTNR 
  FROM T246 
  INTO ld_weekday_number.
