How can I intercept a timeout for long-running processes?  

Question

In a BSP application, large collections in the OnInitialization event handler can cause a timeout on the next page. This timeout should be intercepted, and an appropriate error message should be displayed without losing the session context. How can I do this?

Answer

You can solve the problem of long-running processes by starting these processes in a second thread, so that the front-end thread can quickly display the next HTML page in the browser. In ABAP, this corresponds to the call function … in background task call

On this next page, you can use the HTML refresh mechanism. This automatically refreshes the page after a set amount of time has elapsed – 20 seconds, for example. The system displays a progress display and a message informing you that the system is still busy.

Synchronization of the front end task with the process task is performed by the database.
