ABAP code example for Function Module OIU_DN_IS_NEXT_NODE_WC

The ABAP code below is a full code listing to execute function module OIU_DN_IS_NEXT_NODE_WC 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).

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_wl
 
 TYPE OIU_PR_WC-WL_NO ,
ld_i_ref_no
 
 TYPE SY-SUBRC ,
ld_e_wc
 
 TYPE OIU_PR_WC-WC_NO ,
ld_i_mp
 
 TYPE OIU_PR_MP-MP_NO .


ld_i_ref_no = 'some text here'.

SELECT single MP_NO 
  FROM OIU_PR_MP 
  INTO ld_i_mp.
