There is one more thing you can do to identify the problem.

Check your component in SE80 on your Quality system hitting (CTRL-F2) .

Hi Ashish,

the "MAIN." within the error message "Subnode MAIN. does not exist " is suspicious.

Normally this should be "MAIN.SOMENODE" which corresponds to <Viewname>.<Nodename of table which you want to display in ALV>.

I think there is a problem with the external mapping to your SALV_WD_ALV-usage.

I would suggest to recreate the external mapping and import it again.

Hi Ashish,

How you are importing the changes to quality system through TR only right,Did you done any enhancemetns for that,check that those properly transported or not.

     This error because of your accessing some node,but that not no exist in your view,compare it from development system.

Thanks,

Hi Lavnya ,

yes i am doing import through TR only i have compared the code only code is same the problem is in ERQ node name is blank so when is it coming to method

data node_info_child_nodes type WDR_CONTEXT_CHILD_INFO_MAP.
     node_info_child_nodes = me->node_info->if_wd_context_node_info~get_child_nodes( ).
     read table node_info_child_nodes with key name = name assigning <info_data>.
     if 0 <> sy-subrc.
       _temp_Buffer = me->node->if_wd_context_node~get_path( ).
       concatenate _temp_Buffer name into _temp_Buffer separated by '.'.
       raise exception type cx_wd_context
         exporting textid = cx_wd_context=>child_not_exists
                   node_name = _temp_Buffer.
     endif.

then on 4th line sy-subrc value is 4 so its raising exception
