https://community.appian.com/discussions/f/process/2241/hi-i-was-going-through-exception-handling-described-inHi, I was going through Exception Handling described in forum.appian.com/.../Handling_Process_Exceptions . Is there a way we can catch an expression in a process similar to try..catch? Say, an error occurs in &#39;Write To Datastore&#39; smart service call.

On user input task, you can easy show message base on value of your set variable (ri!blErrorOccured). &nbsp;</p> <p><a href="/cfs-file/__key/communityserver-discussions-components-files/14/pastedimage1540534234218v1.png"><img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/14/pastedimage1540534234218v1.png" alt=" " /></a></p> <p>2. You can add AND gate after start event and wait till some time, like 2 or 3 hour (more than usual time your process takes to complete), if your process don&#39;t complete in that time frame, it means some error has occurred, you can display an interface with proper message.&nbsp;</p> <p>&nbsp;</p> <p><a href="/cfs-file/__key/communityserver-discussions-components-files/14/pastedimage1540534520516v2.png"><img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/14/pastedimage1540534520516v2.png" alt=" " /></a></p> <p>Regards,</p> <p>Simple Shah</p><div style="clear:both;"></div>https://community.appian.com/thread/61940?ContentTypeID=1Thu, 25 Oct 2018 16:03:02 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:47392bde-12d6-4fe5-a536-42c1d8089a27Robert ShankinInternal (&quot;hidden&quot;) functions should not be used to design applications.<br /> They could be deprecated at any time.
