ABAP code example for Function Module RS_TREE_LIST





The ABAP code below is a full code listing to execute function module RS_TREE_LIST 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:
it_list  TYPE STANDARD TABLE OF SNODETEXT,"TABLES PARAM
wa_list  LIKE LINE OF it_list .


DATA(ld_node_id) = Check type of data required
DATA(ld_all) = 'some text here'.
DATA(ld_with_attributes) = 'some text here'.
DATA(ld_hidden_nodes) = 'some text here'.

"populate fields of struture and append to itab
append wa_list to it_list. . CALL FUNCTION 'RS_TREE_LIST' * EXPORTING * node_id = ld_node_id * all = ld_all * with_attributes = ld_with_attributes * hidden_nodes = ld_hidden_nodes TABLES list = it_list EXCEPTIONS CYCLE_DETECTED = 1 NODE_NOT_FOUND = 2 . " RS_TREE_LIST

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_node_id  TYPE SNODE-ID ,
it_list  TYPE STANDARD TABLE OF SNODETEXT ,
wa_list  LIKE LINE OF it_list,
ld_all  TYPE STRING ,
ld_with_attributes  TYPE STRING ,
ld_hidden_nodes  TYPE STRING .


ld_node_id = Check type of data required

"populate fields of struture and append to itab
append wa_list to it_list.
ld_all = 'some text here'.
ld_with_attributes = 'some text here'.
ld_hidden_nodes = 'some text here'.
