Binding Nodes problem

[Former Member]

Hi everybody.

I'm new on Web Dynpro development, and I have the follwing problem :

I have two tables element on my view (T1 and T2).

When I select one row of T1, I want to fill the table T2 with new data. (dynamically). So each time I select a new row of T1, the T2 data is updated.

I have two solutions :

- A node N1 for table T1 (cardinality : 0,N) and a node N2 for table T2 (cardinality : 0,N) within N1. In this case, I think the second table will be updated automtically ? If yes, how can I bind the the second node ? I have a DDIC table structure within a table structure too.

- A node N1 (cardinality : 0,N) and a node N2 (cardinality : 0,N) separated. When I select the row on T1 with the event 'onSelect' ,I get the row selected, I fill N2 with the correct data (binding process).

What's the best solution ?

Thank you.

Hi,

You can achieve it in both the ways.

1st approach is using the SUPPLY FUNCTION for better performance. everything is expalined in this link

Check out this link that suits your requirement -

Hi Bernard,

For first option, i think this can be achieved through 'Recursion Node', am not completely sure, but I remember ive done something of this kind of requirement using recursion node.

You always have the second option which you suggested in case no other approach works.

Cheers,
