ABAP code example for Function Module CHECK_NODE_ENQUEUE

The ABAP code below is a full code listing to execute function module CHECK_NODE_ENQUEUE 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_node_locked  
 
 TYPE MATGRP_STRUC-NODE
.


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


DATA(ld_uname) = some text here
 

SELECT single NODE 
  FROM MATGRP_STRUC 
  INTO @DATA(ld_node_to_check).

 

SELECT single HIER_ID 
  FROM MATGRP_HIER 
  INTO @DATA(ld_hierid).

CALL FUNCTION 'CHECK_NODE_ENQUEUE'
  EXPORTING

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_matgrp_lock
 
 TYPE CHAR1 ,
ld_node_locked
 
 TYPE MATGRP_STRUC-NODE ,
ld_node_to_check
 
 TYPE MATGRP_STRUC-NODE ,
ld_uname
 
 TYPE SEQG3-GUNAME ,
ld_hierid
 
 TYPE MATGRP_HIER-HIER_ID .


ld_matgrp_lock = 'Check type of data required'.

SELECT single NODE 
  FROM MATGRP_STRUC 
  INTO ld_node_to_check.


ld_uname = some text here

SELECT single HIER_ID 
  FROM MATGRP_HIER 
  INTO ld_hierid.
