Which BMC product are you using?
Thanks for responding, i am using BMC incident management tool
Depending on the version of something called AR System Server, which is running the Incident Management application.
>9 then you can use REST (I would use python, but up to you)
<9 use Web Services
A guy called Carl Wilson created a great document on using it
The form, equivalent of a database table, is called HPD:IncidentInterface
And use the query of 'Assigned Group*' = "Your Group"
