Mantis Bug Tracker - Forums

example:
issue 1 falls into machine model1,2,3, then we have 3 projects at mantis M1,M2,M3,
so the id will be M1000001,M2000001,M300001

does it sounds good?
or any recommendation?

a) the id would contain redundant information
b) the id would have to be changed, when an issue is moved from one project to another
c) if the id is changed in case b) the links in previous emails for an issue will fail
d) there would be a lot of changes in database model of MantisBT (currently the id is integer not string)
e) ....

So I think, it does not sound good

Maybe using the relationships feature of MantisBT can help you in some way?
