Data is not displaying using ABAP WebDynPro

[Former Member]

Hi,

Thanks in Advance.

I am trying to get the data of field AUFNR and KTEXT from AUFK table into Layout.

These are the attributes of Change Node

Node Name PROD_ORDER

Interface Node : No

Input Element (Ext.) : No

Dictionary structure AUFK

Cardinality : 0..n

Selection : 0..1

Init. Lead Selection : Yes

Singleton : No

Supply Function

Mapping Path

*************************

Method :

I have written the following code to fetch the data from AUFK table

method WDDOINIT .

Data: it_AUFK type standard table of AUFK,

context_node type ref to if_wd_context_node.

select AUFNR KTEXT from AUFK INTO table it_AUFK.

if sy-subrc eq 0.

context_node = wd_context->get_child_node( name = 'PROD_ORDER').

context_node->bind_table( it_AUFK ).

endif.

endmethod.

There is no syntax error and getting activated. But while testing no data or even column is displaying into browser. It is blank page.

Am not sure where I am wrong. Please assist me.

Thanks

I tried using both the select statement. Data is also there in the table. Still blank page is displaying without any error.

Let me know.

Instead of this :

select AUFNR KTEXT from AUFK INTO table it_AUFK.

Try this :

select AUFNR KTEXT from AUFK INTO corresponding fields of table it_AUFK.

If it doesnt work, try to debug the application and check the value of it_AUFK.

Have you instantiated teh ALV or....have you mapped the DATA node of ALV to the PROD ORDER node or not..usnder the compoent usages check it out..

If you have used the TABLE UI element have you created teh bindign to the table to this PROD_ORDER node or not..

Hi,

Are you getting the data in it_aufk table?? If yes, then there must be something wrong with the mapping. Just check the mapping between DATA node of ALV and Prod_Order node. Try to delete the mapping between DATA node of ALV and Prod_order node and map them again. It might work.

Hi ,

Check this for testing purpose :

Afer you have binded the internal table to the node , check if node has some vlaues in it or not :

Use this code to get the data of node into an internal table and see if the node is getting populating with data or not :

DATA lo_nd_cn_table TYPE REF TO if_wd_context_node.
    DATA lo_el_cn_table TYPE REF TO if_wd_context_element.
    DATA ls_cn_table TYPE wd_this->element_cn_table.
DATA it_table  TYPE wd_this->elements_cn_table.
*   navigate from <CONTEXT> to <CN_TABLE> via lead selection
    lo_nd_cn_table = wd_context->get_child_node( name = wd_this->wdctx_cn_table ).
 
*lo_nd_cn_table->get_static_attributes_table( IMPORTING table = lt_table).*

<CN_table is my node binded to table.>
