Manage User Imports

edited August 7 in Modeling

I'm developing a Demand Planning Model for school books.

Every year, it is critical to update the list of SKUs [both delete and add SKUs] as well as the SKU details [School Subject, School Year, Type of Book] - in the systems module

Given that these SKU information are also lists in my ANAPLAN model, I would need to have my users import all of these lists [once a year], but I am concerned that this will lead to errors.

Could you please give some best practices for dealing with this?
Thank you very much.
