Trouble importing System module to Numbered List
I'm trying to import a system module containing flat list dimensions (store, product) containing line items that combines store and product code into a combined numbered list that up until now only have stores in it. When running the import I get below failure messages although import was completed:
* Another row has already been processed with this key
* Cannot import record into numbered list as it has a new name
I believe my list doesn't understand that the same product should be able to be sold in different stores. Also, when having a numbered list I cannot uniquely identify data with my code or combination of properties, but only Name (#ID), which I suppose is the Product name, so that is causing problems.
I tried the same import for a dummy non-Numbered list and it then worked. But how can I make this work with a numbered list? Do I have to maybe add some line item calculation row to my system module that I'm importing?
