Thank you in advance.

In your ADD button event handler code

data: lr_node type ref to if_wd_context_node.

data: count type i.

lr_node = wd_context->get_child_node( '<node name binded to the table>' ).

count = lr_node->GET_ELEMENT_COUNT( ).

if count > 10.

• show a message

exit.

endif.

rest of your code adding

Hi,

I think its a local variable and every time the button is pressed it is initiated again to one. Can you suggest any method to declare a global variable.

count it a local variable, but you are filling it with the current table size using the method GET_ELEMENT_COUNT. it will always return the number of rows in your table node.

if you want another way.

go to the Attribute tab of the View

add a Variable of type Integer

you can access this variable using WD_THIS-><variable_name> in any of the methods of your View
