ABAP code example for Function Module SMLG_GET_DEFINED_SERVERS

The ABAP code below is a full code listing to execute function module SMLG_GET_DEFINED_SERVERS 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:

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_grouptype
 
 TYPE RZLLITAB-GROUPTYPE ,
it_instances
 
 TYPE STANDARD TABLE OF RZLLIAPSRV ,
wa_instances
 
 LIKE LINE OF it_instances,
ld_groupname
 
 TYPE RZLLITAB-CLASSNAME .



SELECT single GROUPTYPE 
  FROM RZLLITAB 
  INTO ld_grouptype.
 

"populate fields of struture and append to itab
append wa_instances to it_instances.

SELECT single CLASSNAME 
  FROM RZLLITAB 
  INTO ld_groupname.
