Cardinality Voilates

[Former Member]

hi all,

i am getting the errror

• Number of Elements of the Collection of Node FORMVIEW.1.EMPLOYEEDATA Violates the Cardinality.
• in my app i have created a structure from an internal custom ztable in which two other attributes are also used

don't know why it is showing this error although each parameter set by me is right

Cardinality for view and component controller is 1.1

pls see screenshot and help in this

Hi Manu,

If you are using table UI element on your layout screen then create the binding node with 0:N cardinality.

If you are using form or multiple input elements then use 0:1 cardinality.

Please let us know what type of UI element you are using.

Hi Manu,

I am not sure if still you are facing the error or not as the question was posted almost 2 months back.

Looking into the screenshots given by you and the code you have written it seems that you are trying to display employee details in a form fetching from a table.

Please try to set the cardinality of your context node as 1.1 as you are displaying one employee record at a time and not displaying multiple records in a table and keep the Initialization lead selection property as checked.

Then in you WDDOINIT after selecting one record from the table read in a work area(structure) and set it in the context node using set_static_attributes method of the lead selected element.

Hope this helps.

Thanks,

Hi Manu,

Have you tried 0:1 cardinality?

hi Mahinder,

on cardinality=0.1 & selection=0.1 for view,controller&window

the following error is displayed

• Adapter error in &VIEW_ELEMENT_TYPE& "EMPNO" of view "ZWA_MYPROJECT1.FORMVIEW": Context binding of property ? cannot be resolved: Node FORMVIEW.1.EMPLOYEEDATA does not contain any elements

on cardinality 1.1

yes

everytime i change the cardinality a new error message is being displayed

[Former Member]

Then you should change the cardinality to 0:N and selection is 0:1.  You please try this.

thanks and Regards,

can you add screen shots of your node property and code you have written in wddoinit.

[Former Member]

method WDDOINIT .

*   *data declaration

  data: Node_emp   type REF TO IF_WD_CONTEXT_NODE,

        Itab_emp   type standard table of ZZZ_EMP,

      lo_el_context TYPE REF TO if_wd_context_element,

      ls_context TYPE wd_this->element_context,

      lv_lv_user LIKE ls_context-lv_user.

*    get element via lead selection

      lo_el_context = wd_context->get_element(  ).

*    get single attribute

      lo_el_context->get_attribute(

        EXPORTING

          name =  `LV_USER`

        IMPORTING

          value = lv_lv_user ).

* get data from table SFLIGHT

   select * from ZZZ_EMP into table Itab_emp WHERE Empno = lv_lv_user.

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

   Node_emp = wd_Context->get_Child_Node( Name = `EMPLOYEEDATA` ).

* bind internal table to context node <SFLIGHT>

   Node_emp->Bind_Table( Itab_emp ).

endmethod.

pls see method and attached screenshots

[Former Member]

you are binding a table in context node with cardinality 1:1.

if your cardinality is 1:1 means there can only be one instance can be bind.

solution: use select

select single * from ZZZ_EMP into table Itab_emp WHERE Empno = lv_lv_user.

or you can change caridnality to 0:n.
