Dynamic Progress indicator at web-dyn-pro ABAP

[Former Member]

Hi Expert,

I need to achieve a dynamic Progress indicator at web-dyn-pro ABAP. When I trigger a event, its working . But I need to do it automatically, as the value changes at back-end, the progress bar will also change at display.

Is it possible to achieve ? Any one have any idea ??

Thanks in advance..

Its must to trigger an event to change value of progress indicator.

But if you know after a certain time certain amount of progress will over then you can use timedtrigger UI element.

Suppose You know after 2 sec value will be changed from 10% to 20% then in the onaction of timedtrigger UI element you can increase that amount. then set delay as 2 seconds after every 2 seconds automatically an action will be triggered.

As stated up to NetWeaver 7.01 you have to trigger an event to check and update the progress status. Sometimes people use the TimedTrigger at certain intervals to check the status.

However in NetWeaver 7.02, early next year, we have a new Notification Service in WDA. It allows the long polling of event status via AJAX. It doesn't lock the screen and does a very fast, lightweight call to only the ICM - so no Web Dynpro Phase Model or even dip into the ABAP work process. This makes it possible to basically have the push of the status updates from an Asychronous process.

I've done an eLearning on this new technology and we will show it more at TechEd this year:
