Blocking issue with timeouts

Hi,
We have an application job (power builder) that runs on the app server every 5 minutes to load data into a table. Occassionally the job times out without completing but this can lead to an inactive transaction that will cause blocking. I have been manually issuing the kill command to stop the blocking.

Any ideas on how to clear up the issue from a sql server side? Any code we can put in the powerbuilder app to clear the inactive transaction?



Thanks

Rebecca
