ABAP code example for Function Module MECH_SAVE_UNIT

The ABAP code below is a full code listing to execute function module MECH_SAVE_UNIT 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 UNINM 
  FROM RODUNI 
  INTO @DATA(ld_i_uninm).

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_e_subrc
 
 TYPE STRING ,
ld_i_dtelnm
 
 TYPE DCOBJDEF-NAME ,
ld_i_uninm
 
 TYPE RODUNI-UNINM ,
ld_i_applnm
 
 TYPE ROAPPL-APPLNM .



ld_i_dtelnm = some text here

SELECT single UNINM 
  FROM RODUNI 
  INTO ld_i_uninm.


SELECT single APPLNM 
  FROM ROAPPL 
  INTO ld_i_applnm.
