How to read or get subnode as table operation

[Former Member]

Hi experts!

I have a question ...

I have a parent node and want to get the values ​​of the child node. This child node has cardinality 0..n. Wanted to know a way to get the value of it for each record in the parent node.

The child node like it to be sort an internal table.

I tried to do so, but the child node is empty ... Since there are records for it ...

[code]

DATA lt_node_export_pdf         TYPE ypcadt_risk_control_pdf.

   DATA ls_node_export_pdf         TYPE ypcads_risk_control_pdf.

   DATA lt_risk_history            TYPE ypcadt_risk_status_history_exp.

   DATA ls_risk_status_history_exp TYPE ypcads_risk_status_history_exp.

   DATA lo_nd_node_export_pdf      TYPE REF TO if_wd_context_node.

   DATA lo_el_node_export_pdf      TYPE REF TO if_wd_context_element.

   DATA lt_collection              TYPE wdr_context_element_set.

   DATA lo_nd_risk_status_exp      TYPE REF TO if_wd_context_node.

   DATA lt_risk_status_exp         TYPE ypcadt_risk_status_history_exp.

   DATA ls_risk_status_exp         TYPE wd_this->element_risk_status_exp.

* navigate from <CONTEXT> to <NODE_EXPORT_PDF> via lead selection

   lo_nd_node_export_pdf = wd_context->get_child_node( name = wd_this->wdctx_node_export_pdf ).

   lt_collection = lo_nd_node_export_pdf->get_elements( ).

   LOOP AT lt_collection INTO lo_el_node_export_pdf.

     lo_el_node_export_pdf->get_static_attributes( IMPORTING static_attributes = ls_node_export_pdf ).

*   navigate from <CONTEXT> to <RISK_STATUS_EXP> via lead selection

     lo_nd_risk_status_exp = wd_context->path_get_node( path = `NODE_EXPORT_PDF.RISK_STATUS_EXP` ).

     lo_nd_risk_status_exp = lo_el_node_export_pdf->get_child_node( 'RISK_STATUS_EXP' ).

     lo_nd_risk_status_exp->get_static_attributes_table( IMPORTING table = lt_risk_status_exp ).

     ls_node_export_pdf-t_risk_history = lt_risk_status_exp.

     APPEND ls_node_export_pdf TO lt_node_export_pdf.

ENDLOOP.

[/code]

In case I want to populate a field of the internal table with the values ​​found in the child node. This field is a subtable.

Thanks for your attention people!

Hi Fabiana,

Try this way:

lo_nd_risk_status_exp = wd_context->path_get_node( path =`NODE_EXPORT_PDF.RISK_STATUS_EXP` ).

*---the line below is New

lo_el_node_export_pdf = lo_el_node_export_pdf->get_element( sy-tabix ). "Use a variable for Loop sy-tabix

*---
lo_nd_risk_status_exp = lo_el_node_export_pdf->get_child_node( 'RISK_STATUS_EXP' ).

Regards,
