context mapping for two webservices (retrieve data / change data)

31 Views

Hi,

I have two webservices. WS_1 retrieves the data from the SAP backend and diplays them on view_1. Between ws_1 and view_1 I have a custom controller (cust_1).

Now I like to edit the data on the view_1 and send back the edited data with another webservice (ws_2).

My question is now how I must do the context mapping? Do I need another custom controller(cust_2) for my ws_2? If yes I must map cust_2 to view_1, too. But how can I construct context mapping between the two custom models? The data from cust_1 must be mapped to cust_2. By using a "delta link" I only was able to add the values from cust_2 as additional values to cust_1. But I must map the results from cust_1 to the parameter from cust_2.

Thanks a lot for every tip.

Bye,

Henning
