Hi Peter
You could use the SubString function.
So if I wanted to return in another attribute the first 5 characters in the title of a incident, you could make the new attribute as a before save calculation with the title as a dependency and the following calculation.
import System
static def GetAttributeValue(Incident):
Value = Incident.Title.Substring(0,5)
return Value
for more information on the above function you can see the following.
String.Substring Method (System)
Not sure where this would piece together in your integration but i help it helps.
Thanks
Paul
