Auto save in webdynpro ABAP

[Former Member]

One of the users is facing a timeout error after entering considerable amount of data in the ALV grid. So, I want to save the contents of the ALV grid in a temporary table after every 30 sec. So that if a timeout occurs I can retrieve the contents from the table and display it in the grid. Is there an auto save feature in webdynpro ABAP? If not then is there a better way to handle this?

No. There is no autosave feature in the WDA framework. This is something you would have to build into your specific application. You could of course use the TimedTrigger UI element to trigger a server event a specified time interval and save the data. Just the act of the TimedTrigger is actually enough to reset the server and ICM session timeout, but you could also save the data into a temp table if you wanted. 30 seconds seems rather extreme, however. You have to remember that the server event will interrupt the user data entry and they will see the waiting icon and the screen will freeze while the server event occurs.
