Bolt set-up is something quite complex.
So, in order to understand where is your problem, you shold post here many images about BTSE, Bolt spec, SBOL, DTAB etc etc...
Why don't you contact your local Aveva Office?
You need to change BLTMETHOD attribute of your piping specs to NEW.
But this could not be enough to have calculation OK.
It involves other steps.
I think you should attend a proper training course as this could be quite a complex subject.
