Hi Manu,

You will have to set the attribute which all are bind  to the input fields on the screens, for that you can use the code wizard and set the appropriate value to each of the attribute .

If you need any help regarding code let me know.

Thanks and Regards,

Can you share the code wherein you  have binded the data

Hello Manu,

                 Do following changes

1) Make the cardinality of the table as 0..n.

2) go to wddoinint method. click on wizard + Set + as table operation choose the table node from the context.

3) write the select query before bind_table method .

4) lastly dont forget to include your view in the window.

Hope this thing works.

Hi Manu.

What is the cardinality of the context element? When you bind a table to the context you have to create a UI Element that can show data with cardinality 1:n or 0:n like Table or Multi Pane Elements.

Try to change the cardinality of context to 0:1 or 1:1 and bind only one line of the table to the context node (for example: lo_nd_node->bind_structure( ls_structure_of_node ).

When you want to change multiple lines of table try to implement a function (Btn) to jump to the next and previous line to change the context.

did you actually bind some data after selcet from database with node using eigther supply function or any method in wddoinit

[Former Member]

no i didn't write any code in any method

i want to do it by wizard

do i have to

when i have bound the fields i think i dont need to

it must show it on browser

pls correct me if wrong?

[Former Member]

You have to select the Data and bind it to context in Supply or wddoinit method. When you create the context and add a structure of a table it only helps to create the context attributes.
