In Grain, there are two models of operation: Standard model where Scale Tickets are directly associated to the Assembly and Scale Ticket Level Management where Scale Tickets have an independent relationship to the Assembly. Setup for these two models is inherently different and therefore are not interchangeable within Grain.
The Scale Ticket Level Management model provides extra flexibility of editing individual or bulk tickets even with settled units. Additionally, the ability to group Scale Tickets for settling, editing, and reporting as well as primary natures of Splits on Scale Tickets with Assemblies inheriting their values makes this model a very powerful tool.
