How to bind table to a subnode

[Former Member]

Hi

In my context i have Node called PARENT_NODE which contains a sub node called CHILD_NODE.

Is there a way to bind a table to the CHILD_NODE ? the sub node is in cardinality 0...n 

i wrote:

data: context_node type ref to if_wd_context_node.

data: lt_table type table of childe_node.

context_node = wd_context-> get_child_node( name = 'PARENT_NODE.CHILDE_NODE').

context_node->bind_table( lt_table ).

when i test my webdynpro i get the error

"SUBNODE.PARENT.CHILD_NODE DOES NOT EXIST".

Is there a way to correct that ???

Thanks Ami

Hi AMI

In order to fill the data into sub-node (CHILD_NODE) you have to use the concept of SUPPLY FUNCTION.

• Goto CONTEXT,
• select subnode
• Give some method name in the beside SUPPLY FUNCTION in properties of the child_node
• Double click on the given name in the supply function field
• Uncomment lines starting from 13 till end of the method
• Implement the required coding before the BIND_TABLE method
• here is the same code, EKKO is the parent node name and EKPO is the child node name
• Based on lead selection in EKKO  automatically EKPO node entries are fetched using SUPPLY FUNCTION concept.

DATA ls_parent_attributes TYPE wd_this->element_ekko.

parent_element->get_static_attributes(
IMPORTING
static_attributes = ls_parent_attributes ).


* data declaration
DATA lt_ekpo TYPE wd_this->Elements_ekpo.
DATA ls_ekpo LIKE LINE OF lt_ekpo.
* @TODO compute values
* e.g. call a data providing FuBa

* Manual coding
SELECT * FROM EKPO
INTO CORRESPONDING FIELDS OF TABLE lt_ekpo
WHERE ebeln = ls_parent_attributes-ebeln.
* Manual coding

* bind all the elements
node->bind_table(
new_items            =  lt_ekpo
set_initial_elements = abap_true ).

• Please refer to the link for further clarification Supply function

Points Please if helpful

Hi Ami,

You should get the path of parent node, then you can bind anything to your child node.

lo_nd_<child_node> = wd_context->path_get_node( path = `<parent node name >.<child node name>` ).

Try this you will able to execute.
