This was deprecated years ago now, there were other PS projects in the works but not sure if they materialized - if you need something similar try zone approvals, not the suite approvals buindle, that is way off functionality-wise. Main reason it was pulled was that it allowed e.g. vendor bill approval for people without access, and the scripts inherently had some issues with lack of control structures, so it would also post said bills into closed periods etc. It is nice though and a lot of customers still use it I believe (lack of alternative)
