Create new List Item from Module
I have a hierarchical list of Customers where the bottom two levels are Customer and Branch. I've got a separate hierarchy for products which as its bottom level has SKU. Due to space considerations our Anaplan consultant created a level below Branch for SKU, where items are only created where there is data. We've got actions that import transactions into a LOAD list, then a DATA module in terms of that LOAD list with a view that facilitates creating Branch->SKU list items when they exist in the data.
We now have the requirement that some forecast data is loaded in at the Customer and SKU level then broken down into Branches (based on actual data which is by Branch/SKU). Due to size issues I'm planning on creating a level below Customer which has the SKU, so we'd end up with; "P6 SKU", "C8 CustId", "C9 Branch", "C10 SKU" by Branch and now "C9 SKU by CustId". I can create the C9 SKU by CustId items using the same method as C10, however I'm trying get my head around how to handle breaking these figures down by branch, when the C10 items relating to each branch/SKU may not have been created for a given Customer/SKU.
The step I think I'm missing would be a module that enables creation of the missing Branch/SKU C10 list items, however I'm not sure how to construct that. I'm new to Anaplan, and have only seen List item creation from a module that uses a LOAD list.
Am I thinking about this in the right way? How can I get the additional C10 list items created so I can end up with a module that can do the spreading of Customer/SKU to Branch/SKU?
