Hello Kiran,

What I am doing is the following:

1 - Within the WDA component

2 - The user clicks a button

3 - This button calls a Z transaction in a pop-up

4 - The user clicks save

5 - The WDA closes the pop-up get the parameters and back to the home screen.

My problem is in step 5. I thought in trigger an event the WDA through the ABAP code, but not know if I can and not find any source to show me the path.

Thanks,

Hi,

I am afraid that your step-5 is not realizable as you wish. You do not have a facility to subscribe to a event other than WDA components.

Your best option is to go for a Server side cookie. When you leave the transaction, write the intended data to the server cookie and read it back from WebDynpro on close of the window.

Ok, But what idea can you give me to know that the user clicked to save and what should I close the pop-up?

Thank you.

Just before opening the popup , you can save the popup instance in a attribute of type if_wd_window and use the method SET_ON_CLOSE_ACTION to subscribe to close event.

In the event handler you can call the function module/Server cookie to see if you have data. In the data string save a attribute to conclude save/cancel actions.
