SDP on prem deluge custom function doubts

Hi, Team,

is there a way to know previous field values on Deluge, for instance, when you have a custom function triggered by a business rule and want to know the previous technician's value when you have the condition "Technician is modified"? The requestObj gives you the new value... what about the previous one?
In a custom function triggered by a business rule, is it possible to "Abort process execution" with a deluge code line?

thanks.
