ABAP code example for Function Module UNICODE_RFC8B

The ABAP code below is a full code listing to execute function module UNICODE_RFC8B 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_username) = 'some text here'.

DATA(ld_exercise) = 'some text here'.

DATA(ld_source) = 'some text here'.

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

SELECT single TEXTID 
  FROM TECHED03_UTEXT 
  INTO @DATA(ld_textid).

 

SELECT single TEXT 
  FROM TECHED03_UTEXT 
  INTO @DATA(ld_text).

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_username
 
 TYPE SYUNAME ,
ld_exercise
 
 TYPE TED_A_EXERCISE ,
ld_source
 
 TYPE SYSYSID ,
ld_logon_langu
 
 TYPE SYLANGU ,
ld_textid
 
 TYPE TECHED03_UTEXT-TEXTID ,
ld_text
 
 TYPE TECHED03_UTEXT-TEXT .


ld_username = 'some text here'.
ld_exercise = 'some text here'.
ld_source = 'some text here'.
ld_logon_langu = 'Check type of data required'.

SELECT single TEXTID 
  FROM TECHED03_UTEXT 
  INTO ld_textid.


SELECT single TEXT 
  FROM TECHED03_UTEXT 
  INTO ld_text.
