Time outs in Web Dynpro

[Former Member]

Hi,

How does SAP applications handle sessions time outs in Web Dynpro for ABAP when the processing takes a long time. Can we change some configuration settings so that we can have a Web Dynpro application can run for a very long time without getting into time-outs?

Hi Sridhar,

Certain Profile parameters can be changed to increase the 'Time out' time. Default is 60 secs. I am not sure what value it is good to set it to. But please contact your Basis team to have this modified (if required; its not advised though).

Thanks, liz

WDA uses a Dialog Work Process just like a SAPGUI session and is subject to the same timeout limit on continuous processing within this work process.

In addition there is also a separate timeout parameter at the ICM level. This controls how long the HTTP connection is held open while wiating on the Diag Work Process to complete its work. The ICM time out is generally set shorter than the dialog WP timeout - default is set to 60 seconds.
