Values not copying in Ship-to-Address Search help

Hi Experts,

I have created a elementary custom search help for delivery address (BBP_ADDR_BUPA_SHIPTO) and successfully getting the selection in the pop-up. But the selection is not copying into the screen.

I have also created a collective search help and added this elementary search help to it.

I have done the Parameter assignment as well.

When I execute the collective search help in SE11, the entries are getting copied.

But when I am executing it in WD component. the selection entries are not getting copied.

I have added the below code on WDINIT post-exit:

1. Data: lo_nd_attrib type ref to if_wd_context_node, 
2.          lo_nd_attrib_info type ref to if_wd_context_node_info. 
3. *  Get the Node and Attribute Information 
4. lo_nd_attrib = wd_context->path_get_node( path = `Node PATH` ). 
5. lo_nd_attrib_info = lo_nd_attrib->get_node_info( ). 
6. * Set the custom search help that need to be executed for the context attribute 
7. lo_nd_attrib_info->set_attribute_value_help( name = 'ATTRIBUTE_NAME' value_help_mode = '121' value_help = 'ZCUSTOM_SEARCHHELP' ). 

Can you please help me in this issue.
